COMMISSION IMPLEMENTING REGULATION (EU) 2023/1695

of 10 August 2023

on the technical specification for interoperability relating to the control-command and signalling subsystems of the rail system in the European Union and repealing Regulation (EU) 2016/919

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Directive (EU) 2016/797 of the European Parliament and of the Council of 11 May 2016 on the interoperability of the rail system within the European Union [(1)](#ntr1-L_2023222EN.01038001-E0001), and in particular Article 5(11) thereof,

Whereas:

|  |  |
| --- | --- |
| (1) | Commission Regulation (EU) 2016/919 [(2)](#ntr2-L_2023222EN.01038001-E0002) lays down the technical specification for interoperability (TSI) relating to the ‘control-command and signalling’ (CCS) subsystems. |

|  |  |
| --- | --- |
| (2) | Pursuant to Article 3(5), points (b) and (f) of Commission Delegated Decision (EU) 2017/1474 [(3)](#ntr3-L_2023222EN.01038001-E0003), TSIs are to be reviewed in order to take into account the developments of the Union railway system and related research and innovation activities, and update references to standards. |

|  |  |
| --- | --- |
| (3) | On 24 January 2020, in accordance with Article 19(1) of Regulation (EU) 2016/796 of the European Parliament and of the Council [(4)](#ntr4-L_2023222EN.01038001-E0004), the Commission asked the European Union Agency for Railways (the ‘Agency’) to prepare recommendations implementing a selection of the specific objectives set out in Articles 3 and 7 of Delegated Decision (EU) 2017/1474. |

|  |  |
| --- | --- |
| (4) | On 30 June 2022, the Agency issued a recommendation relating to the CCS subsystems (ERA-REC-1175-1218-2022/REC). This Regulation is based on that recommendation. |

|  |  |
| --- | --- |
| (5) | The existing regulatory framework should be modernised in order to enable new functionalities associated with the digitalisation of railway networks. The efficiency and sustainability of rail freight should be improved through further harmonisation of the European Rail Traffic Management System (ERTMS) and a broader and more systematic deployment of the ERTMS across the Union, notably on trans-European transport network. |

|  |  |
| --- | --- |
| (6) | The new functionalities associated with digitalisation of railway networks and identified in the ERTMS Longer Term Perspective Report of the Agency required the update of the TSI on CCS subsystems. These new technologies requested by the railway sector, as well, were the Future Railway Mobile Communication System (FRMCS), automated train operations, advanced train positioning, and digital automatic couplers. |

|  |  |
| --- | --- |
| (7) | Therefore, this revision delivers both full specifications for automated train operations (Grade of Automation 2) and the interface to FRMCS, which were available. Full FRMCS, advanced train positioning, and digital automatic coupler specifications were not yet available due to the need for further development. |

|  |  |
| --- | --- |
| (8) | In order to keep pace with technological progress, innovative solutions may be required, which do not comply with the specifications set out in the Annex I or for which the assessment methods set out in the Annex I cannot be applied. Such innovative solutions, especially those coming from the Europe’s Rail Joint Undertaking (ERJU), should be promoted and their voluntary implementation should, under certain conditions, be allowed. For this purpose it is appropriate to provide a process harmonised for all Member States to validate such innovative solutions for voluntary implementation. |

|  |  |
| --- | --- |
| (9) | Commission Implementing Decision (EU) 2021/1730 [(5)](#ntr5-L_2023222EN.01038001-E0005) establishes the harmonised conditions for the availability and efficient use of radio spectrum for the Railway Mobile Radio (RMR). Member States are required to use these frequencies in order to plan the deployment of FRMCS. |

|  |  |
| --- | --- |
| (10) | The European Train Control System (ETCS) is the main signalling and control-command system used as part of the ERTMS. To adapt it to the updated needs of the rail sector, two new system versions of the ETCS (system version 2.2 and system version 3.0) are introduced in the latest update of ETCS, i.e. Baseline 4 and included in this revision. System version 2.2 is fully backwards compatible. System version 3.0 is not compatible because it includes functionalities, which are required on-board when implemented track-side. |

|  |  |
| --- | --- |
| (11) | In order to achieve further harmonisation of the ERTMS, this revision provides a new coherent transition and migration regime, ensures a robust procedure for correcting errors in specifications, reduces the scope for partial fulfilment, and phases out the need for compatibility checks. |

|  |  |
| --- | --- |
| (12) | The new transition and migration regime has been developed to provide a consistent framework for the deployment of new functionalities in relation to the CCS TSI on the rail network. The aim of this regime is to ensure a balance between the interests of railway stakeholders, in particular infrastructure managers and railway undertakings. |

|  |  |
| --- | --- |
| (13) | Considering the fact that the ERTMS is a complex software-based system requiring active specification maintenance, the Agency in its capacity of system authority for the ERTMS should support the correction of errors in ERTMS specifications. To ensure safety and interoperability, the procedure to implement these error corrections into the interoperability constituents and CCS subsystems should be specified. |

|  |  |
| --- | --- |
| (14) | Full TSI compliance ensures the achievement of the Single European Rail Area from a technical point of view. It ensures interoperable vehicles and increases their potential reuse value. Partial fulfilment was initially perceived as necessary to take into account some national constraints, but should be reduced significantly in scope in this regulation to reach the goal above. |

|  |  |
| --- | --- |
| (15) | Even a successful certification process cannot always prevent one of the subsystems repeatedly failing to function or perform as intended under certain conditions when an on-board CCS subsystem interacts with a trackside CCS subsystem. Therefore, checks should be carried out to demonstrate the technical compatibility of the CCS subsystems in the area of use for a vehicle. |

|  |  |
| --- | --- |
| (16) | These checks should be considered a temporary measure to increase confidence in the technical compatibility between the subsystems. The principles applicable to those checks should be transparent and prepare the ground for further harmonisation. The possibility of conducting those checks in a laboratory representing the trackside configuration to be made available by the infrastructure manager should be prioritised. To reduce the checks to a minimum, each Member State should promote harmonisation within its infrastructure. |

|  |  |
| --- | --- |
| (17) | Consideration should be given to the steps required to increase, in the shortest possible time, confidence in the technical compatibility of on-board units with different trackside implementations of ERTMS and to reduce and eliminate the tests or checks needed to prove the technical compatibility of on-board units with different trackside implementations of ERTMS. Therefore, the Agency should assess the underlying technical divergences and decide on the necessary steps to eliminate the need for tests or checks to prove the technical compatibility of on-board units with different trackside implementations. |

|  |  |
| --- | --- |
| (18) | Analysing train detection systems aims at improving the interoperability and harmonisation of the European railway system, where economically feasible. Part of this analysis is the transparent identification of non TSI compliant train detection systems. |

|  |  |
| --- | --- |
| (19) | Regulation (EU) 2016/919 should therefore be repealed. |

|  |  |
| --- | --- |
| (20) | The measures provided for in this Regulation are in accordance with the opinion of the Committee established in accordance with Article 51(1) of Directive (EU) 2016/797, |

4.1.2.   Overview of the requirements

All requirements in point 4.2 (Functional and technical specifications of the Subsystems) related to these basic parameters shall be applied to the Class A system.

Requirements for Class B systems and for STMs (which enable the Class A On-board system to operate on Class B infrastructure) are the responsibility of the relevant Member State.

This TSI is based on the principles of enabling the Control-Command and Signalling Trackside Subsystem to be compatible with TSI-compliant Control-Command and Signalling On-board Subsystems. To achieve this goal:

|  |  |
| --- | --- |
| (1) | functions, interfaces and performance of the Control-Command and Signalling On-board Subsystem are standardised, ensuring that every train will react in a predictable way to data received from trackside; |

|  |  |
| --- | --- |
| (2) | for the Control-Command and Signalling Trackside Subsystem, track-to-train and train-to-track communication are fully standardised in this TSI. The specifications referenced in the points below allow Control-Command and Signalling trackside functionality to be applied in a flexible way, so that it can be optimally integrated into the railway system. This flexibility shall be exploited without limiting the movement of vehicles with TSI-compliant on-board subsystems. |

The Control-Command and Signalling functions are classified in categories indicating whether they are optional or mandatory. The categories are defined in point 7.2.9 of this TSI and in specifications referred to in Appendix A and these texts also state how the functions are classified.

Appendix A, Table A.1, 4.1 c provides the Glossary of ETCS and ATO terms and definitions, which are used in the specifications referred to in Appendix A.

4.1.3.   Parts of Control-command and Signalling Subsystems

4.2.1.   Control-Command and Signalling reliability, availability and safety characteristics relevant to interoperability

This basic parameter describes the requirements for the Control-Command and Signalling On-board Subsystem and Trackside subsystem with reference to point 3.2.1 (Safety) and point 3.2.2 (Reliability and Availability).

In order to achieve interoperability, when implementing Control-Command and Signalling On-board and Trackside subsystems the following provisions shall be respected:

|  |  |  |  |  |  |
| --- | --- | --- | --- | --- | --- |
| (1) | The design, implementation and use of a Control-Command and Signalling On-board or Trackside subsystem shall not export any requirements:   |  |  | | --- | --- | | (a) | across the interface between Control-Command and Signalling On-board and Trackside subsystems in addition to the requirements specified in this TSI; |  |  |  | | --- | --- | | (b) | to any other subsystem in addition to the requirements specified in the corresponding TSIs. | |

|  |  |
| --- | --- |
| (2) | The requirements set out in points 4.2.1.1 and 4.2.1.2 below shall be respected. |

4.2.1.1.   Safety

The Control-Command and Signalling On-board and Trackside subsystems shall respect the requirements for ETCS equipment and installations stated in this TSI.

For the hazard ‘exceeding speed and/or distance limits advised to ETCS’ the tolerable hazard rate (THR) shall be 10-9 h-1 for random failures of the on-board ETCS and 10-9 h-1 for random failures of the trackside ETCS. See Appendix A, Table A 1, 4.2.1 a.

To achieve interoperability, the on-board ETCS shall fully respect all requirements specified in Appendix A, Table A 1, 4.2.1. Nevertheless, less stringent safety requirements are acceptable for trackside ETCS provided that, in combination with TSI-compliant Control-Command and Signalling On-board subsystems, the safety level for the service is met.

For the ETCS Class A system:

|  |  |
| --- | --- |
| (1) | the changes made by railway undertakings and infrastructure managers to implement preventive or corrective maintenance actions shall be managed in compliance with the processes and procedures of their safety management system according to Article 9 of Directive (EU) 2016/798 of the European Parliament and of the Council (Safety Directive) [(7)](#ntr7-L_2023222EN.01038701-E0007); |

|  |  |
| --- | --- |
| (2) | other types of changes made by railway undertaking and infrastructure managers (e.g. changes of the design or implementation of ETCS), as well as the changes made by other actors (e.g. manufacturers or other suppliers) shall be managed according to the risk management process set out in Annex I to the Implementing Regulation (EU) No 402/2013, as referred to in Article 6(1)(a) of Directive (EU) 2016/798. |

Additionally, the correct application of the risk management process as set out in Annex I to Implementing Regulation (EU) No 402/2013, as well as the appropriateness of the results from this application, shall be independently assessed by a CSM assessment body according to Article 6 of that Regulation. There shall not be restrictions with respect to the type A, B or C of independence of the CSM assessment body permitted by Implementing Regulation (EU) No 402/2013. The appointed CSM assessment body shall be accredited or recognised according to the requirements in Annex II to Implementing Regulation (EU) No 402/2013 in the field of ‘Control-Command and Signalling’ sub-system, as listed in item 5 ‘classification’ of ERADIS database entry for Assessment Bodies.

The accreditation, or recognition, in the field of ‘Control-Command and Signalling’ sub-system, covers the CSM assessment body competence to independently assess the ‘safe integration’ at the level of an ETCS subsystem, or an ETCS Interoperability Constituent. This includes the competence for:

|  |  |
| --- | --- |
| (1) | the assessment of safe integration of all internal components and interfaces that form the architecture of the ETCS subsystem or ETCS Interoperability Constituent; |

|  |  |
| --- | --- |
| (2) | the assessment of safe integration of all external interfaces of the ETCS subsystem, or ETCS Interoperability Constituent, within its direct physical, functional, environmental, operational and maintenance context. |

The application of the standards as referred to in Appendix A, Table A 3 is an appropriate means to fully comply to the risk management process as set out in Annex I to the Implementing Regulation (EU) No 402/2013 for design, implementation, production, installation and validation (incl. Safety acceptance) of interoperability constituents and subsystems. When different standards from the ones referred to in Appendix A, Table A 3 are applied, at least equivalence shall be proven.

Whenever for an ETCS subsystem or an ETCS Interoperability Constituent the specifications as referred to in Appendix A, Table A 3 are used as an appropriate means to fully comply to the risk management process as set out in Annex I to the Implementing Regulation (EU) No 402/2013, in order to avoid unnecessary duplication of independent assessment work, the independent safety assessment activities that are required by the specifications referred to in Appendix A, Table A 3 shall be carried out by a CSM assessment body accredited or recognized as specified in the point above instead of a CENELEC independent safety assessor.

4.2.1.2.   Availability/Reliability

This point refers to the occurrence of failure modes not causing safety hazards but creating degraded situations, the management of which could decrease the overall safety of the system.

In the context of this parameter, ‘failure’ means the termination of the ability of an item to perform a required function with the required performance and ‘failure mode’ means the effect by which the failure is observed.

To ensure that the relevant infrastructure managers and railway undertaking are given all the information they need to define appropriate procedures for managing degraded situations, the technical file accompanying the EC declaration of verification for an on-board or trackside CCS subsystem shall contain the calculated availability/reliability values related to failure modes having an impact on the capability of the CCS subsystem to supervise the safe movement of one or more vehicles or to establish radio voice communication between traffic control and the train drivers.

Compliance with the following calculated values shall be ensured:

|  |  |
| --- | --- |
| (1) | Mean time of hours of operation between failures of a CCS on-board subsystem requiring the isolation of the train protection functions: (open point); |

|  |  |
| --- | --- |
| (2) | Mean time of hours of operation between failures of a CCS on-board subsystem preventing radio voice communication between traffic control and the train driver: (open point). |

To allow the infrastructure managers and railway undertakings to monitor, during the life of the subsystems, the level of risk and the respect of the reliability/availability values used for the definition of procedures to manage degraded situations, the requirements for maintenance stated in point 4.2.20 (Technical documentation for Maintenance) shall be respected.

It is expected that these checks will be reduced until the principle stated in 6.1.2.1 is achieved.

4.2.17.1.   ETCS System Compatibility

ETCS System Compatibility (ESC) is the recording of technical compatibility between ETCS on-board and the trackside parts ETCS of the CCS subsystems within an area of use.

Each ESC Type identifies the set of ESC checks (e.g. document check, lab or track test, …) applicable for a section or group of sections within an area of use. It is possible to use the same ESC type for cross border infrastructure and for different national infrastructures.

The results of the ESC checks for an on-board unit on the Interoperability Constituent level or subsystem level, including findings and conditions arising, are recorded in the ESC Check Report.

‘Representative configuration’ means a configuration on the basis of which test results can be achieved, which are valid for various configurations of the same certified ETCS on-board interoperability constituent or of a certified on-board subsystem. These results shall also be equivalent for various configurations of a certified ETCS trackside subsystem.

For ESC checks at ETCS on-board Interoperability Constituent level the following is to be observed:

|  |  |
| --- | --- |
| (1) | The ESC Interoperability Constituent Statement records the ESC results of the ETCS On-board Interoperability Constituent to the ESC Type(s) that is valid regardless of the specific configuration of the ETCS on-board Interoperability Constituent. This document shall be produced by the on-board supplier. The template provided in Appendix C.2 or C.6 shall be used. |

|  |  |
| --- | --- |
| (2) | The ESC Interoperability Constituent Statement shall include the summary of the findings and conditions of the ESC Check Report(s) on the results of the ESC checks passed (defined in one or more ESC Type), which are valid independently from the specific configuration parameters of the on-board Interoperability Constituent and can therefore be used in every applicable specific on-board CCS subsystem level. |

|  |  |
| --- | --- |
| (3) | The ESC Interoperability Constituent Statement shall include the list of ESC checks performed for the ESC Type(s). |

|  |  |
| --- | --- |
| (4) | The ESC Interoperability Constituent Statement shall include the reference to the NoBo assessment Report according to 6.2.4.3 (ETCS and radio system compatibility checks for Interoperability Constituent). |

The ESC of the specific on-board CCS subsystem with respect to one or more ESC Type(s) is laid down in the ESC Statement. The template provided in Appendix C.1 or C.5 shall be used.

At subsystem level, the ESC Statement shall also include the summary of the ESC Check Report and shall demonstrate the fulfilment of the required ESC checks (for each ESC Type included in the Statement) published in the Agency ESC/RSC technical document in addition to already provided ESC interoperability constituent statements.

The ESC Statement shall also include the full list of ESC Interoperability Constituent statements taken into account in the assessment (if any), the conditions (if any) with respect to the different ESC Types and the NoBo Assessment Report according to 6.3.3.1 (ETCS and radio system compatibility checks).

4.2.17.2.   Requirements for ETCS System Compatibility

The Infrastructure Manager is responsible for defining the ESC type(s). All sections of the Union network which require the same set of checks for the demonstration of ESC shall have the same ESC type.

The list of ESC Types is published and maintained by the European Union Agency for Railways in the technical document ‘ESC/RSC technical document, TD/011REC1028’. See Appendix A, Table A 1, 4.2.17 a. The Agency shall assess the checks unless they have been assessed by a NoBo as required in Table 6.3 row 10. The assessment by the Agency shall be done within 2 months of receipt thereof, unless a longer period is agreed between the Agency and the Infrastructure Manager but not exceeding 4 months in total. The technical document will be updated within 10 working days after positive assessment.

The ESC Types shall only be used when published with status ‘Valid’ in the Agency Technical document referred above.

Infrastructure Managers, with the support of the ETCS suppliers for their network, shall submit to the Agency the definition of the necessary checks for each ESC type on their network. The minimum information that shall be included:

|  |  |
| --- | --- |
| (1) | Definition of each check to be performed. |

|  |  |
| --- | --- |
| (2) | Criteria to pass each check. |

|  |  |
| --- | --- |
| (3) | If a check is only required for trains compatible with a specific M\_VERSION functionality and a given TSI release. |

|  |  |
| --- | --- |
| (4) | If checks are to be performed in laboratories or on the track. In case of track, it shall be indicated if a specific location is required. |

|  |  |
| --- | --- |
| (5) | Contact details in order to request the performance of each check. |

|  |  |
| --- | --- |
| (6) | Description of the representative configuration of a check whenever defined by the relevant IM to be performed in a laboratory. |

|  |  |
| --- | --- |
| (7) | Proposal of the transition period between the new version of ESC Types definition and prior version, or the national procedure. It shall also be indicated the validity of the previous ESC Types. The final transition period shall be agreed with the Agency. In the absence of agreement it will be 6 months. |

Infrastructure Managers shall classify the ETCS lines according to ESC Types and register the ESC Types in RINF. If no ESC definition is published in the ESC/RSC Technical Document or received by the Agency for existing lines equipped with ETCS, it shall be considered that no ESC checks are required for the concerned lines.

Infrastructure Manager shall provide the necessary means, laboratory or access to the infrastructure, to perform the checks, as required by Article 6 of Implementing Regulation (EU) 2018/545.

Infrastructure Managers shall submit to the Agency any changes on the referred checks for their network.

The ESC types are valid indefinitely unless modified or withdrawn by the Infrastructure Manager. In case of changes, the provisions on 7.2.3.4 (Impact on the technical compatibility between on-board and trackside parts of the CCS subsystems) shall be respected. If an on-board needs to be rechecked, only the new/updated ESC checks need to be done, applying the principle that already passed checks remain valid, if the vehicle is not modified.

When ESC checks are published or updated by the Agency in the technical document ‘ESC/RSC technical document, TD/011REC1028’, the corresponding existing National Rules for ETCS compatibility testing shall be withdrawn and only ESC checks shall be performed to demonstrate technical compatibility between subsystems. The IM shall indicate the equivalence (none, partial or complete) of the ESC with the previous national procedure, if existing. In such a case, Interoperability Constituent or subsystems which have demonstrated technical compatibility with the previous national procedure, may reuse that as evidence for the demonstration of compliance with the equivalent part of the new ESC without the need to execute the checks again. If not fully equivalent, the IM shall indicate a transition period as mentioned in point (7) above.

The Entity in charge of ESC demonstration shall define a representative configuration of the ETCS on-board subsystem.

The ESC Statement shall be produced by the Entity applying for ESC Demonstration.

The Entity applying for ESC Demonstration shall have the ESC check report for the Interoperability Constituent or Subsystem assessed by a Notified Body according with points 6.2.4.3 (ETCS and radio system compatibility checks for Interoperability Constituent) or 6.3.3.1 (ETCS and radio system compatibility checks).

If a Check Report or an ESC Interoperability Constituent Statement referred to in the ESC Statement contains Conditions, all Conditions shall be recorded, reflecting the status and if agreed how they are managed by the affected party (e.g. RU willing to demonstrate the compatibility with a route), and this responsibility shall be recorded in the ESC Statement.

4.2.17.3.   Radio System Compatibility

Radio System Compatibility (RSC) is the recording of technical compatibility between voice or data radio on-board and the trackside parts of RMR of the CCS subsystems within an area of use.

Each RSC Type identifies the set of RSC checks (e.g. document check, lab or track test) applicable for a section or group of sections within an area of use. It is possible to use the same RSC type for cross border infrastructure and for different national infrastructures.

The results of the RSC checks for an on-board voice or data radio part on the Interoperability Constituent level or subsystem level, including findings and conditions arising, are recorded in the RSC Check Report.

Representative Configuration means a configuration on the basis of which test results can be achieved, which are valid for various configurations of the same certified Interoperability Constituent or of a certified on-board subsystem. These results shall also be equivalent for various configurations of a certified RMR trackside subsystem.

For RSC checks at Interoperability Constituent level the following is to be observed:

|  |  |
| --- | --- |
| (1) | The RSC Interoperability Constituent Statement records the RSC results of the Interoperability Constituent (e.g. Cab Radio or EDOR) to the RSC Type(s) that is valid regardless of the specific configuration of the Interoperability Constituents. This document shall be produced by the supplier. The template provided in Appendix C.4 or C.6 shall be used. |

|  |  |
| --- | --- |
| (2) | The RSC Interoperability Constituent Statement shall include the summary of the findings and conditions of RSC Check Report(s) on the results of the RSC checks passed (defined in one or more RSC Type), which are valid independently from the specific configuration parameters of the on-board Interoperability Constituent and can therefore be used in every applicable on-board CCS subsystem level. |

|  |  |
| --- | --- |
| (3) | The RSC Interoperability Constituent Statement shall include the list of RSC checks performed for the RSC Type(s). |

|  |  |
| --- | --- |
| (4) | The RSC Interoperability Constituent Statement shall include the reference to the NoBo assessment Report according to 6.2.4.3 (ETCS and radio system compatibility checks for Interoperability Constituent). |

The RSC of the specific on-board CCS subsystem with respect to one or more RSC Type(s) is laid down in the RSC Statement. The template provided in Appendix C.3 or C.5 shall be used.

At subsystem level, the RSC Statement shall also include the summary of the Check Report and shall demonstrate the fulfilment of the required RSC checks (for each RSC Type included in the Statement) published in the Agency ESC/RSC technical document in addition to already provided RSC interoperability constituent statements.

The RSC Statement shall also include the full list of RSC Interoperability Constituent statements taken into account in the assessment (if any), the conditions (if any) with respect to the different RSC Types and the NoBo Assessment Report according to 6.3.3.1 (ETCS and radio system compatibility checks).

In case of changes, the provisions on 7.2.3.4 (Impact on the technical compatibility between on-board and trackside parts of the CCS subsystems)shall be respected. If an on-board needs to be rechecked, only the new/updated RSC checks need to be done, applying the principle that already passed checks remain valid, if the vehicle is not modified.

When RSC checks are published or updated by the Agency in the technical document ‘ESC/RSC technical document, TD/011REC1028’, the corresponding existing National Rules for Radio compatibility testing shall be withdrawn and only RSC checks shall be performed to demonstrate technical compatibility between subsystems. The IM shall indicate the equivalence (none, partial or complete) of the RSC with the previous national procedure, if existing. In such a case, Interoperability Constituent or subsystems which have demonstrated technical compatibility with the previous national procedure, may reuse that as evidence for the RSC without the need to execute the checks again.

The ‘Realisation identifier’ is part of the system identifier and means a figure or a number of figures defined by the individual configuration management of a supplier, which represents a specific configuration (e.g. HW and SW) of a CCS subsystem or Interoperability Constituent. The ‘system identifier’, ‘functional identifier’ and ‘realisation identifier’ shall be defined by each supplier.

4.4.   Operating rules

The rules for operating a railway service with ETCS, ATO and RMR are specified in the Operation and Traffic Management TSI.

The harmonised text indications and messages displayed on the ETCS Driver Machine Interface are listed under Appendix E.

4.5.   Maintenance rules

The maintenance rules of the subsystems covered by this TSI shall ensure that the values quoted in the basic parameters indicated in Chapter 4 are maintained within the required limits throughout the lifetime of the subsystems. However, during preventative or corrective maintenance, the subsystem may not be able to respect the values quoted in the basic parameters; the maintenance rules shall ensure that safety is not prejudiced during these activities.

The entity in charge of the Control-Command and Signalling Subsystems shall set up maintenance rules to achieve the above objectives. The preparation of these rules shall be done with the assistance of the requirements in 4.2.20 (Technical documentation for Maintenance).

4.6.   Professional competences

The manufacturers of the equipment and of the subsystem shall provide information sufficient to define the professional competences required for the installation, final inspection and maintenance of the Control-Command and Signalling Subsystems. See point 4.5 (Maintenance rules).

4.7.   Health and safety conditions

Care shall be taken to ensure health and safety for maintenance and operations staff, in accordance with Union legislation and the national legislation that is compatible with the Union legislation.

Manufacturers shall indicate the risks for health and safety that arise from using and maintaining their equipment and subsystems. See point 4.4 (Operating rules) and point 4.5 (Maintenance rules).

4.8.   Registers

The data to be provided for the registers provided for in Articles 48 and 49 of Directive (EU) 2016/797 are those indicated in Commission Implementing Decision 2011/665/EU [(14)](#ntr14-L_2023222EN.01038701-E0014) and Commission Implementing Regulation (EU) 2019/777 [(15)](#ntr15-L_2023222EN.01038701-E0015).

4.9.   Route compatibility checks before the use of authorised vehicles

The parameters of the on-board CCS subsystem to be used by the railway undertaking, for the purpose of route compatibility check, are described in Appendix D1 of Implementing Regulation (EU) 2019/773.

5.   INTEROPERABILITY CONSTITUENTS

5.1.   Definition

In accordance with Article 2(7) of Directive (EU) 2016/797, interoperability constituents means any elementary component, group of components, subassembly or complete assembly of equipment incorporated or intended to be incorporated into a subsystem, upon which the interoperability of the rail system depends directly or indirectly, including both tangible objects and intangible objects.

5.2.   List of interoperability constituents

5.2.1.   Basic interoperability constituents

The basic interoperability constituents in the Control-Command and Signalling Subsystems are defined in:

|  |  |
| --- | --- |
| (1) | Table 5.1. for the Control-Command and Signalling On-board Subsystem; |

|  |  |
| --- | --- |
| (2) | Table 5.2. for the Control-Command and Signalling Trackside Subsystem. |

5.2.2.   Grouping of interoperability constituents

|  |  |  |
| --- | --- | --- |
|  | 5.2.2.1. | The functions of basic interoperability constituents may be combined to form a group. This group is then defined by those functions and by its remaining external interfaces. If a group is formed in this way, it shall be considered as an interoperability constituent. Compliance of interfaces internal to the group of Interoperability Constituents to basic parameters of Chapter 4 does not have to be verified. Compliance of interfaces external to the group of Interoperability Constituents has to be verified to demonstrate conformity with the basic parameters related to the requirements of these external interfaces. |

|  |  |  |  |  |  |  |  |  |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
|  | 5.2.2.2. | When interoperability constituents are grouped, the grouped functions and their addressing must be configurable in such a way that the grouped functions of the ATO, ETCS and the radio ICs can be replaced during the life cycle of the CCS subsystem by an external ATO, ETCS or Radio ICs. Therefore, the following interfaces in a grouped Interoperability Constituent shall be made externally accessible on the CCS Consist network communication layers as specified in Appendix A, Table A 1, 4.2.6 i:  |  |  | | --- | --- | | (1) | Interface between ATO On-Board and ETCS On-Board as specified in Appendix A, Table A 1, 4.2.6 h; |  |  |  | | --- | --- | | (2) | Interface between ATO On-Board and GSM-R data radio On-Board as specified in Appendix A, Table A 1, 4.2.6 j; |  |  |  | | --- | --- | | (3) | Interface between On-board FRMCS and the CCS applications (ETCS in Appendix A, Table A 1, 4.2.6 g and ATO in Appendix A, Table A 1, 4.2.6 k); | |

5.3.   Constituents’ performance and specifications

For each basic interoperability constituent or group of interoperability constituents, the tables in Chapter 5 describe:

6.   ASSESSING THE CONFORMITY AND/OR SUITABILITY FOR USE OF THE CONSTITUENTS AND VERIFYING THE SUBSYSTEMS

6.1.   Introduction

6.1.1.   General principles

6.1.1.1.   Compliance with basic parameters

Fulfilment of the essential requirements set out in Chapter 3 of this TSI shall be ensured through compliance with the basic parameters specified in Chapter 4.

This compliance shall be demonstrated by:

|  |  |
| --- | --- |
| (1) | assessing the conformity of the interoperability constituents specified in Chapter 5 (see points 6.2.1, 6.2.2, 6.2.3, 6.2.4); |

|  |  |
| --- | --- |
| (2) | verifying the subsystems (see point 6.3 and point 6.4). |

In case of changes to existing subsystems, the requirements in 7.2.2 for on-board subsystems and 7.2.3 for trackside subsystems shall be considered in the assessment.

6.1.1.2.   Partial fulfilment of TSI requirements

An on-board subsystem may, if fulfilling both conditions below, not implement all mandatory functionalities specified in this TSI:

|  |  |
| --- | --- |
| (1) | the functionalities are listed in Appendix G; |

|  |  |
| --- | --- |
| (2) | the Infrastructure Manager (with the support of the Member State) has indicated in RINF that the partial fulfilment of the listed requirement does not prevent an optimal and safe operation on its network. |

Where a control-command and signalling interoperability constituent or subsystem does not implement all functionalities specified in this TSI, the relevant conditions for use shall reflect it in accordance with provisions of points 6.5.1 and 6.5.2.

6.1.2.   Principles for testing ETCS, ATO and RMR

6.1.2.1.   Principle

The principle is that a Control-Command and Signalling On-board Subsystem covered by an ‘EC’ declaration of verification is able to run on every Control-Command and Signalling Trackside Subsystem covered by an ‘EC’ Declaration of verification, under the conditions specified in this TSI, with no additional verifications.

Achievement of this principle is facilitated by:

|  |  |
| --- | --- |
| (1) | rules for the design and installation of the Control-Command and Signalling On-board and the Trackside subsystems; |

|  |  |
| --- | --- |
| (2) | test specifications to prove that the Control-Command and Signalling On-board and Trackside Subsystems comply with the requirements of this TSI and are mutually compatible. |

6.1.2.2.   Operational test scenarios

For the purpose of this TSI, an ‘operational test scenario’ means a sequence of trackside and on-board events related to or influencing the Control-command and Signalling subsystems (e.g. sending/receiving messages, exceeding a speed limit, actions of operators ) and the specified timing between them in order to test the intended railway system operation in situations relevant for ETCS, ATO and RMR (e.g. entry of a train into an equipped area, awakening of a train, overriding a signal at stop).

The operational tests scenarios are based on the engineering rules adopted for the project.

Check of compliance of a real implementation with an operational test scenario shall be possible gathering information through easily accessible interfaces (preferably the standard interfaces specified in this TSI).

6.1.2.3.   Requirements for Operational test scenarios

The set of engineering rules for the trackside parts of ETCS, ATO and RMR and related operational test scenarios for the Trackside Control-command and Signalling Subsystem shall be sufficient to describe all intended system operations relevant for the Trackside Control-command and Signalling Subsystem in normal and identified degraded situations, and:

|  |  |
| --- | --- |
| (1) | shall be consistent with the specifications referenced in this TSI; |

|  |  |
| --- | --- |
| (2) | shall assume that functions, interfaces and performance of the Control-command and Signalling On-board Subsystems interacting with the Trackside Subsystem are compliant with the requirements of this TSI; |

|  |  |
| --- | --- |
| (3) | shall be the ones used in the EC Verification of the Trackside Control-command and Signalling Subsystem, to check that the implemented functions, interfaces and performance are able to ensure that the intended system operation in combination with the relevant modes and transitions between levels and modes of the Control-command and Signalling On-board Subsystems are respected. |

6.2.   Interoperability constituents

6.2.1.   Assessment procedures for Control-Command and Signalling Interoperability Constituents

Before placing on the market an interoperability constituent and/or groups of interoperability constituents the manufacturer or his authorised representative established within the European Union shall draw up an ‘EC’ declaration of conformity in accordance with Article 9(2) and Article 10(1) of Directive (EU) 2016/797.

The assessment procedure shall be carried out using one of the modules specified in point 6.2.2 (Modules for Control-Command and Signalling Interoperability Constituents).

An ‘EC’ declaration of suitability for use is not required for Control-Command and Signalling interoperability constituents. Compliance with relevant basic parameters, as demonstrated by the ‘EC’ Declaration of conformity, is sufficient for placing the interoperability constituents on the market [(16)](#ntr16-L_2023222EN.01038701-E0016).

6.2.2.   Modules for Control-Command and Signalling Interoperability Constituents

For assessing interoperability constituents within the Control-Command and Signalling Subsystems, the manufacturer or his authorised representative established within the European Union, may choose:

|  |  |
| --- | --- |
| (1) | either the type-examination procedure (Module CB) for the design and development phase in combination with the production quality management system procedure (Module CD) for the production phase; or |

|  |  |
| --- | --- |
| (2) | the type-examination procedure (Module CB) for the design and development phase in combination with the product verification procedure (Module CF); or |

|  |  |
| --- | --- |
| (3) | the full quality management system with design examination procedure (Module CH1). |

In addition, for checking the SIM card and Marker Board Interoperability Constituent, the manufacturer or his representative may choose Module CA.

The modules are described in detail in the Commission Decision 2010/713/EU [(17)](#ntr17-L_2023222EN.01038701-E0017).

The following clarifications apply to the use of some of the modules:

|  |  |
| --- | --- |
| (1) | with reference to Chapter 2 of the ‘Module CB’, ‘EC’-type examination shall be carried out through a combination of production type and design type; |

|  |  |
| --- | --- |
| (2) | with reference to Chapter 3 of the ‘Module CF’ (product verification) statistical verification is not allowed, i.e. all interoperability constituents shall be individually examined. |

6.2.3.   Assessment requirements

Independently of the selected module:

|  |  |
| --- | --- |
| (1) | the requirements stated in point 6.2.4.1 of this TSI shall be respected for the ‘On-board ETCS’ interoperability constituent; |

|  |  |
| --- | --- |
| (2) | the activities shown in Table 6.1.1 shall be carried out when assessing the conformity of an interoperability constituent or a group of interoperability constituents as defined in Chapter 5 of this TSI. All verifications shall be carried out by reference to the applicable table in Chapter 5 and the basic parameters indicated there. |

|  |  |
| --- | --- |
| (3) | The manufacturer of the equipment shall inform a Notified Body about all changes affecting the conformity of the Interoperability Constituent due to the requirements of the applicable TSI release. The manufacturer shall also demonstrate if these specifications of error corrections require new checks, in accordance with Table 6.1.1 and by application of modules for the EC Conformity according to 6.2.2. This information shall be provided by the manufacturer with corresponding references to the technical documentation relating to the existing EC certificate. The manufacturer shall justify and document that applicable requirements are met at interoperability constituent level, which shall be assessed by a Notified Body. |

The manufacturer shall inform the impacted entities about changes, e.g. regarding operation and maintenance, if they affect existing and already implemented products/components.

6.2.4.   Special issues

6.2.4.1.   Mandatory tests for the on-board ETCS

Particular attention shall be given to assessing the conformity of the on-board ETCS interoperability constituent, since it is complex and plays a key role in achieving interoperability.

Regardless of whether module CB or CH1 is chosen, the Notified Body shall check that:

|  |  |
| --- | --- |
| (1) | a representative specimen of the interoperability constituent has been submitted to a full set of test sequences including all test cases necessary to check the functions referenced in point 4.2.2 (On-Board ETCS functionality). The applicant is responsible to define the test cases and their organisation in sequences, if this is not included in specifications referenced in this TSI; |

|  |  |  |  |  |  |
| --- | --- | --- | --- | --- | --- |
| (2) | these tests were carried out in a laboratory accredited in accordance with Regulation (EC) No 765/2008 of the European Parliament and of the Council [(18)](#ntr18-L_2023222EN.01038701-E0018) and the standards referred to in Appendix A, Table A 4 to carry out tests with the use of the test architecture and the procedures specified in Appendix A, Table A 1:   |  |  | | --- | --- | | (a) | For on-board ETCS supporting up to system version 2.1: 4.2.2 c. |  |  |  | | --- | --- | | (b) | For on-board ETCS supporting up to system version 2.2 and 3.0: not included, see previous point (1). | |

The laboratory shall provide a full report clearly indicating the results of the tests cases and sequences used. The Notified Body is responsible to assess the suitability of test cases and sequences to check compliance with all relevant requirements and to evaluate the results of tests in view of the certification of the Interoperability Constituent.

6.2.4.2.   Class B interfaces

Each Member State shall be responsible for verifying that Class B systems and their interfaces to the ETCS on-board Interoperability Constituent conform to its national requirements.

The verification of the standardised STM interface to the on-board ETCS requires a conformity assessment carried out by a Notified Body.

6.2.4.3.   ETCS and radio system compatibility checks for Interoperability Constituent

Since the ESC/RSC checks are not required in Table 6.1.1, they are not required for issuing an interoperability constituent certificate.

If ESC/RSC checks are executed at Interoperability Constituent level, the task of the NoBo with regards to the ESC/RSC Interoperability Constituent statement(s) and associated report is to verify the correctness and completeness of the ESC/RSC check report for the Interoperability Constituent, according to the requirements in this point.

In line with the Directive (EU) 2016/797 the Notified Body performing this assessment may be a different one from the Notified Body performing the EC conformity or suitability procedure for the interoperability constituent.

6.3.3.1.   ETCS and radio system compatibility checks

The task of the NoBo with regards to the ESC/RSC check report is to verify the correctness and completeness of the ESC/RSC check report for the subsystem, according to the requirements in this point.

Since the ESC/RSC checks are not required in Table 6.2.1, they are not needed for issuing an on-board subsystem certificate. Such an on-board subsystem therefore will only be considered compatible with Class A infrastructures where no specific ESC/RSC check is required to demonstrate technical compatibility (i.e. identified by the IM as ESC-EU-0 or RSC-EU-0 in RINF).

The Notified Body shall not check again any aspect covered during the already performed EC Verification procedure for the on-board subsystem or already covered in the ESC/RSC Interoperability Constituent Statement.

In line with the Directive (EU) 2016/797, the Notified Body performing this assessment may be a different one from the Notified Body performing the EC Verification procedure for the on-board subsystem or from the Notified Body performing the assessment on the ESC/RSC Interoperability Constituents check report.

6.3.4.   Assessment requirements for a Trackside Subsystem

The purpose of assessments carried out within the scope of this TSI is to verify that the equipment complies with the requirements stated in Chapter 4.

However, for the design of the ETCS part of the Control-Command and Signalling Trackside Subsystem, application-specific information is needed. This shall include:

|  |  |
| --- | --- |
| (1) | line characteristics such as gradients, distances, positions of route elements and Eurobalises/Euroloops, locations to be protected, etc.; |

|  |  |
| --- | --- |
| (2) | the signalling data and rules to be handled by the ETCS system. |

This TSI does not cover checks to assess whether the application-specific information is correct.

Regardless of the module chosen:

6.4.   Provisions in case of the partial assessment of TSI requirements

6.4.1.   Assessment of parts of control-command and signalling subsystems

Pursuant to Article 15(7) of Directive (EU) 2016/797, the Notified Body may issue EC certificates of verification for certain parts of a subsystem, if allowed to do so under the relevant TSI.

As pointed out in point 2.2 (Scope) of this TSI, the trackside and on-board control-command and signalling subsystems contain parts, as specified in point 4.1 (Introduction), and this section only relates to those defined parts.

An EC certificate of verification may be issued for each part or for a combination of parts specified in this TSI.

Regardless of which module is chosen, the Notified Body shall check that the requirements (all relevant requirements as specified in Table 6.2.1) are fulfilled for:

|  |  |
| --- | --- |
| (1) | the part in question; and |

|  |  |
| --- | --- |
| (2) | its interfaces to the unchanged parts of the subsystem; and |

|  |  |
| --- | --- |
| (3) | the integration with the unchanged parts of the subsystem. |

For the CCS on-board subsystem: In any case of assessment of parts the EC certificate(s) of verification issued by the Notified Body(ies) shall consider one of the following options:

|  |  |
| --- | --- |
| (1) | An EC certificate of verification of the CCS on-board subsystem covering all parts; or |

|  |  |  |  |  |  |
| --- | --- | --- | --- | --- | --- |
| (2) | An EC certificate of verification for each of the following groups of parts:   |  |  | | --- | --- | | (a) | Train protection, data radio communication and automated train operation parts; and |  |  |  | | --- | --- | | (b) | Voice radio communication part. | |

The EC certificate of verification shall state and provide evidence on the fulfilment of all requirements in Table 6.2.1, and on possible interfaces between parts or absence thereof, in one of the following ways:

|  |  |
| --- | --- |
| (1) | the absence of interfaces with the other part/group of parts; or |

|  |  |
| --- | --- |
| (2) | in case of interfaces with the other part/group of parts, the absence of the conditions and limits of use of the other part/group of parts.  In case of interfaces that require conditions and limits of use in line with the requirements specified in the Table 6.2.1 of this TSI and that export constraints to the other part/group of parts, there shall be an EC subsystem certificate; or |

|  |  |
| --- | --- |
| (3) | in case the subsystem consists of only one part/group of parts, no additional assessment on subsystem level is necessary if the assessment of the part/group of parts covers all TSI requirements for that part/group of parts. In this case the EC certificate of verification for the part replaces the subsystem EC certificate of verification. |

6.4.2.   Intermediate Statement of Verification

If conformity is assessed for subsystems specified by the applicant and different from the parts allowed in Table 4.1, and the assessment process is different from the process described in point 6.4.1 (Assessment of parts of control-command and signalling subsystems) of this TSI, or if only certain stages of the verification procedure have been performed, only an intermediate statement of verification may be issued.

6.5.   Management of errors

Where deviations from intended functions and/or performance are detected during the tests or during the operational life of a subsystem, the applicants and/or operators shall inform without delay the Agency and the authorising entity that issued the authorisations for the concerned trackside subsystems or vehicles, to initiate the procedures set out in Article 16 of Directive (EU) 2016/797. As a result of the application of Article 16(3) of that Directive:

|  |  |
| --- | --- |
| (1) | if the deviation is due to incorrect application of this TSI or to errors in design or installation of equipment, the applicant for the relevant certificates shall take the necessary corrective actions and the certificates affected and/or the corresponding technical files (for interoperability constituents and/or subsystems), together with the corresponding EC Declarations, shall be updated; |

|  |  |
| --- | --- |
| (2) | if the deviation is due to errors in this TSI or in specifications referenced therein, the procedure set out in Article 6 of the Directive (EU) 2016/797 shall be initiated. |

The applicants and/or suppliers may be applying their own solution to the identified error once the error related change request has been validated by the Change Control Management (CCM) procedure according to Article 28(2) of Regulation (EU) 2016/796. This validation shall be done within 3 months after the complete information has been submitted.

Any such temporary solution to the identified error, that does not export constraints to the other subsystem, may be applied until the agreed error correction is adopted in a new version of CCS TSI. Once a solution to the identified error is adopted in a new TSI version the applicants and/or suppliers shall apply the adopted solution to the existing vehicles according to the earlier of the following conditions:

|  |  |
| --- | --- |
| (a) | if implementation of error correction does not require authorization: at the next occasion when error correction is mandatory by virtue of table B1.1 row 1 and in any case not before 1.1.2026; |

|  |  |
| --- | --- |
| (b) | if implementation of error correction requires authorization: at the next reauthorisation resulting from another change to the vehicle train protection (ETCS) system; |

|  |  |
| --- | --- |
| (c) | at the next upgrade to a higher system version of the vehicle train protection part. |

|  |  |
| --- | --- |
| Note: | For Interoperability constituents for which the result of the information to be provided as described in point 7.2.10.1 indicates that there is no impact regarding safety, operation and interoperability, an update is not required. |

Error corrections might impact the CCS trackside and CCS on-board subsystems. The Agency shall organise an efficient processing of all the information received in order to facilitate the Change Control Management process for improvement and further development of the specifications, including the test specifications.

6.5.1.   Content of EC certificates

As per Commission Implementing Regulation (EU) 2019/250 [(22)](#ntr22-L_2023222EN.01038701-E0022) the notified bodies shall describe the restrictions and conditions for use of interoperability constituents and subsystems in the relevant EC certificates.

Notified bodies shall coordinate with the Agency the way in which errors, restrictions and conditions for use of interoperability constituents and subsystems are managed in the relevant EC certificates for verification and their accompanying technical files in the working group set up under Article 29 of Regulation (EU) 2016/796.

In the accompanying technical file issued by the NoBo the template of Appendix D shall be used.

6.5.2.   Content of EC declarations

As per Implementing Regulation (EU) 2019/250 the interoperability constituent’s manufacturer or the subsystem applicant shall describe in the EC declaration of conformity or verification the restrictions and conditions for use.

In the accompanying technical files the template of Appendix D shall be used.

7.   IMPLEMENTING THE TSI CONTROL-COMMAND AND SIGNALLING

7.1.   Introduction

This Chapter outlines the technical measures for implementing the TSI, and in particular the conditions for migrating to Class A systems.

Account must be taken of the fact that the implementation of a TSI occasionally has to be coordinated with the implementation of other TSIs.

7.2.   Generally applicable rules

7.2.1.   Upgrading or renewing the Control-Command Subsystems or parts of them

Upgrading or renewing the Control-Command and Signalling Subsystems may concern any or all of the parts constituting them, as specified in point 2.2 (Scope).

The different parts of the Control-Command and Signalling Subsystems may therefore be upgraded or renewed separately, if interoperability is not jeopardised.

See point 4.1 (Introduction) for the definition of the basic parameters for each part.

7.2.2.   Changes to an existing On-Board subsystem

This point defines the principles to be applied by the entities managing the change and authorising entities in line with the EC verification procedure described in Articles 15(9) and 21(12) and Annex IV of Directive (EU) 2016/797. This procedure is further developed in Articles 13, 15 and 16 of Implementing Regulation (EU) 2018/545 and in Decision 2010/713/EU.

This point applies in case of any change(s) to an existing on-board subsystem or on-board subsystem type, including renewal or upgrade. It does not apply in case of changes covered by Article 15(1), point (a) of Implementing Regulation (EU) 2018/545.

7.2.2.1.   Rules to manage changes in on-board CCS subsystems

|  |  |  |
| --- | --- | --- |
|  | (1) | Parts, as defined in Table 4.1 of this TSI, and basic parameters of the on-board subsystem that are not affected by the change(s) are exempt from conformity assessment against the provisions in this TSI. The list of parts and basic parameters affected by the change is to be provided by the entity managing the change. |

|  |  |  |
| --- | --- | --- |
|  | (2) | The entity managing the change shall inform a Notified Body of all changes affecting the conformity of the subsystem with the requirements of the relevant TSI(s) requiring new checks, in accordance with Articles 15 and 16 of Implementing Regulation (EU) 2018/545 and Decision 2010/713/EU and by application of modules SB, SD/SF or SH1 for the EC verification, and if relevant Article 15(5) of Directive (EU) 2016/797. This information shall be provided by the entity managing the change with corresponding references to the technical documentation relating to the existing EC certificate. |

|  |  |  |
| --- | --- | --- |
|  | (3) | The entity managing the change has to justify and document that applicable requirements remain consistent at subsystem level, and this has to be assessed by a Notified Body. |

|  |  |  |
| --- | --- | --- |
|  | (4) | The changes impacting the Basic Design Characteristics of the on-board subsystem are defined in Table 7.1 (Basic Design Characteristics) and shall be classified as Article 15(1), points (c) or (d) of Implementing Regulation (EU) 2018/545, and in accordance with Table 7.1 (Basic Design Characteristics) changes not impacting but related to the Basic Design Characteristics shall be classified by the entity managing the change as Article 15(1), point (b) of Implementing Regulation (EU) 2018/545. |

|  |  |  |  |  |
| --- | --- | --- | --- | --- |
|  | (5) | Changes not covered by point 7.2.2.1(4) above are deemed not to have any impact on the basic design characteristics.

EC design or type certificates of interoperability constituents already placed on the market based on a previous version of this TSI remain valid even if a revision of this TSI comes into force, unless a requirement is applicable at CCS subsystem level which impacts the interoperability constituent (as specified in Table B1.1 or Table B2 of Appendix B) or unless explicitly otherwise specified in the revision of this TSI within Table B3 of Appendix B.

During this time, these interoperability constituents are permitted to be placed on the market without a new design or type examination.

7.2.5.   Legacy systems

Member States shall ensure that the functionality of the legacy systems and their interfaces remains unchanged, except where modifications are needed to mitigate safety-related flaws in these systems [(36)](#ntr36-L_2023222EN.01038701-E0036).

7.2.6.   Availability of Specific Transmission Modules and interfaces to Class B on-board

If trackside that fall within the scope of this TSI are not equipped with the Class A train protection system, the Member State shall ensure the availability of a Specific Transmission Module (STM) or products and/or specifications that would allow the integration of its legacy Class B train protection system with the Class A on-board system. For lines equipped with more than one Class B system, the requirement applies to at least one of these Class B systems.

The Member State shall notify within one year of the entry into force of the TSI, the Class B system (s) for which the requirement is met.

The Class B on-board and its interface, for existing products that have already demonstrated integration with Class A TSI compliant products, shall correspond to any of the technical possibilities defined in point 4.2.6.1. In the case where there is no system available that has already demonstrated integration with Class A TSI compliant on-board system, the solution made available shall be with standardised interface (STM).

The Member State shall notify the specifications of the interfaces between class A and class B on-board train protection systems within 1 year after entry into force of the TSI.

If for a particular class B system, the only solution available in the market is Class B and Class A integrated within the same equipment, the holders of the Class B specifications (e.g. supplier, railway undertaking, infrastructure manager) shall provide the specifications, for the parts they hold, necessary for integration of this Class B system with a compliant ETCS on-board. Any relevant intellectual property they hold shall be made available on a FRAND (fair, reasonable and non-discriminatory) terms basis. The holders of the specifications shall ensure the information provided is sufficient to allow other manufacturers to integrate class B with any ETCS on-board in existing rolling stock.

In this context, due regard is to be given to ensuring an open market for Class B and STM under fair commercial conditions. If, for technical or economic reasons, including applicable intellectual property rights, the availability of an STM or a Class B with its complete interface specifications to a class A system cannot be ensured, the Member States concerned shall inform the Committee referred to in Article 51(1) of Directive (EU) 2016/797 of the underlying reasons for the problem and of the mitigation measures that it intends to put into place in order to allow operators – and in particular foreign operators – access to its infrastructure.

7.2.7.   Additional Class B equipment on a line equipped with Class A

On a line equipped with ETCS and/or RMR, additional Class B trackside equipment may be installed in order to allow the operation of rolling stock not compatible yet with Class A during the on-board Class A deployment phase.

Each Infrastructure Manager shall be responsible for verifying that the trackside design supports transitions between Class A and Class B and does not impose any additional requirements to the CCS Class A on-board, thus the Control-Command and Signalling Trackside Subsystem shall be designed as if Control-Command and Signalling Class A on-board is using standardised interface (STM) between Class A and Class B systems.

7.2.8.   Vehicle with Class A and Class B equipment

Vehicle may be equipped with both Class A and Class B systems to enable operation on several lines.

The Member State concerned may restrict the use of an on-board Class B system on lines where the Class B system is not installed trackside.

A vehicle equipped with both class A and class B shall demonstrate technical compatibility with trackside Class A on lines double equipped with Class A in parallel with Class B. Being equipped with a Class B system in addition to Class A shall not be a requirement for the compatibility of a vehicle with lines where Class B is installed in parallel with Class A.

For vehicle equipped with class A, class B train protection systems may be implemented according to requirements defined in point 4.2.6.1 and following the requirements in point 7.2.6.

7.2.9.   Conditions for mandatory and optional functions

The applicant for EC verification of a Control-command and Signalling Trackside subsystem shall check whether Control-command and Signalling Trackside functions, which are defined ‘optional’ in this TSI, are required by other TSIs, national rules or by the application of risk evaluation and assessment to ensure safe integration of subsystems.

The trackside implementation of national or optional functions shall be technically compatible and not prevent the use of that infrastructure by a train that complies only with the mandatory requirements of the On-board Class A system except as required for the following on-board optional functions in point 7.2.9.1 and 7.2.9.3. The trackside implementation of one of these optional functions which leads to a new mandatory on-board requirement on specific lines shall be notified minimum 5 years before the function can become a mandatory on-board requirement. The notification of a new mandatory on-board requirement shall be done within the RINF and these changes in RINF shall be listed in the Network Statement according to Article 27 of the Directive 2012/34/EU of the European Parliament and of the Council [(37)](#ntr37-L_2023222EN.01038701-E0037). A notification period shorter than 5 years is only allowed if this is agreed between the IM and RU’s who run services or intent to run services (at the time of establishing the agreement) on these lines. This agreement on shortening the notification period shall be notified to the European Commission.

An on-board subsystem which incorporates a KER STM, may make it necessary to implement the K-interface.

7.2.9.1.   ETCS

|  |  |  |
| --- | --- | --- |
|  | (1) | An ETCS Level 2 Trackside application with no or reduced train detection (formerly ETCS level 3) relies on on-board information to determine track occupation and requires that the on-board is able to fulfil the requirements for confirmed train length information as specified in Appendix A, Table A 2, index 27. |

|  |  |  |
| --- | --- | --- |
|  | (2) | An ETCS Level 1 Trackside application with infill requires that the on-board is equipped with the corresponding in-fill data transmission (Euroloop or radio) if the release speed is set to zero for safety reasons (e.g. protection of danger points). |

|  |  |  |
| --- | --- | --- |
|  | (3) | When ETCS needs data transmission by radio, the data radio communication part as specified in this TSI is required. |

|  |  |  |
| --- | --- | --- |
|  | (4) | When ETCS trackside needs a specific ETCS system version, the on-board shall be equipped according to the implementation requirements listed in 7.4.2.4.2. |

7.2.9.2.   ATO

|  |  |  |  |  |
| --- | --- | --- | --- | --- |

Where ATO GoA1/2 functionality is implemented over ETCS trackside, the specifications of ATO in Appendix A of this TSI shall be applied.  |  |  | | --- | --- | | Note: | Where ATO GoA1/2 functionality is implemented over Class B trackside, the specifications of ATO trackside in Appendix A of this TSI should be applied in order to facilitate the future migration to ATO on lines to be equipped with ETCS. | |

|  |  |  |  |  |
| --- | --- | --- | --- | --- |
|  | (2) | ATO on-board: the fitting of ATO in a CCS on-board Subsystem is mandatory [(38)](#ntr38-L_2023222EN.01038701-E0038) when implementing ETCS for the first time into the vehicle and the vehicle is also intended for use on a line including at least one section equipped with ATO where the IM has notified in RINF the services requiring mandatory ATO on-board implementation.  |  |  | | --- | --- | | Note: | Where ATO GoA1/2 functionality is implemented over Class B trackside, the ATO on-board implementation is based on contractual agreements between the IM and RUs and as such there are no mandatory ATO GoA1/2 implementation requirements until ATO trackside and Class B trackside lines are migrated to a fully compliant ETCS including ATO trackside specifications in Appendix A of this TSI. | |

7.2.9.3.   RMR

GSM-R and/or FRMCS shall be implemented according to the implementation requirements listed in point 7.3.2.

7.2.10.   Specifications maintenance (error corrections)

7.2.10.1.   Responsibilities during the Change Control Management process

During the Change Control Management (CCM) process of the ERTMS specifications and before the entry into force of the next legal release of this TSI, errors are classified as preventing normal service or as not preventing normal service.

For the errors preventing normal service, on-board manufacturers, operators, e.g. providing input on the occurrence of the error during normal service, and infrastructure managers with the necessary input from the trackside manufacturers shall describe their products and system implementations with respect to the situation identified by answering to the ERA questionnaires (which include the resolutions of the errors and the mitigation measures).

The answers on these ERA questionnaires shall be provided within 3 months after publication of the questionnaires, in particular the Infrastructure Manager shall evaluate within the ERA questionnaire if:

|  |  |
| --- | --- |
| (1) | the impact of the error is acceptable, as regards safety and network operation; |

|  |  |  |  |  |  |
| --- | --- | --- | --- | --- | --- |
| (2) | the impact of the error is acceptable for interoperability, this either means that:   |  |  | | --- | --- | | (a) | the non-implementation of the trackside error correction would allow any ERTMS vehicle complying with the latest TSI release to provide normal service in the network;  or |  |  |  | | --- | --- | | (b) | the non-implementation of the on-board error correction would allow that ERTMS vehicle to provide normal service in the TSI compliant network. | |

The Agency shall publish the results of the ERA questionnaires in a transparent manner.

7.2.10.2.   On-board and Trackside Manufacturer responsibilities

After the publication of the error corrections in a legal release, manufacturers shall update their Interoperability Constituents accordingly and are responsible for maintaining the Interoperability Constituents as requested in point 4.2.20.1 (including maintaining the associated EC Certificates) and according to the transition requirements in Appendix B (Table B3). These updated Interoperability Constituents (including the associated EC Certificates) shall be made available for integration in the concerned subsystems according to Appendix B (Table B3).

|  |  |
| --- | --- |
| Note: | For Interoperability constituents for which the information previously provided as described in point 7.2.10.1 indicates that there is no impact regarding safety, operation and interoperability, an update is not required. |

7.2.10.3.   Infrastructure Manager and Railway Undertaking responsibilities

7.2.10.3.1.   
Infrastructure Manager responsibilities

In case the impact of one of the errors as described in point 7.2.10.1 is identified as unacceptable on the Infrastructure Manager’s network, the Infrastructure Manager, based on the information previously provided by on-board manufacturers within the ERA questionnaires, shall identify the ERTMS vehicles authorised to run on its network or being authorised to run on its network that have not implemented a solution which mitigates the interoperability or safety problem caused by the specification error. In case of significant impact on existing vehicles running on its network reported by on-board manufacturers (with the support of operators), the Infrastructure Manager can voluntarily decide to evaluate the implementation of temporary trackside mitigation measures in order to facilitate existing vehicles to continue their services until on-board error corrections are implemented.

The Infrastructure Manager shall register in the related RINF [(39)](#ntr39-L_2023222EN.01038701-E0039) parameter which error corrections are applicable (i.e. the errors preventing normal service in the network) for the on-board. This shall be registered at the latest 12 months after the entry into force of the TSI or shall be registered in case of new or upgrade trackside implementation within its network.

For impacted ERTMS trackside subsystems, Infrastructure Managers shall implement the relevant trackside error corrections enabling a TSI compliant CCS on-board (including on-board error correction implementation) to provide a normal service, in accordance with appendix B (Table B2) of this CCS TSI.

This Infrastructure Manager shall update -if applicable- the existing ETCS and radio system compatibility checks type (ESC/RSC) (i.e. this shall not lead to the creation of a new ESC/RSC type).

7.2.10.3.2.   
Railway Undertakings responsibilities

The Railway Undertakings shall compare the error corrections registered in RINF for the area of use of the vehicle with the information previously provided as described in point 7.2.10.1 to identify the necessary error corrections to be implemented in the vehicles.

For impacted ERTMS on-board subsystems, Railway Undertakings with support of the on-board manufacturers shall implement the necessary error corrections in the CCS on-board subsystems in accordance with appendix B (Table B1.1) of this CCS TSI.

7.5.   ETCS and radio system compatibility checks implementation rules

Existing vehicles, and their corresponding vehicle type, equipped with ETCS and RMR shall be deemed compatible with the ETCS and radio system compatibility types of the networks on which they are operating with ETCS and RMR by 16 January 2020 without any further checks, maintaining the existing restrictions or conditions for use.

Any subsequent modification of the vehicle, their corresponding vehicle type or the infrastructure regarding the technical or route compatibility shall be managed according to the requirements specified for ETCS and Radio system compatibility in this TSI.

7.6.   Train detection systems specific implementation rules

In the context of this TSI, train detection system means the equipment installed trackside, which detects the presence or absence of vehicles either on an entire line of route or on a local section of it.

Trackside systems (e.g. interlocking or level crossing control systems) which use information from detection equipment are not considered parts of the train detection system.

This TSI specifies the requirements for the interface with rolling stock only to the extent necessary to ensure compatibility between TSI-compliant rolling stock and the Control-command and Signalling Trackside.

Implementing a train detection system that is compliant with the requirements of this TSI can be done independently of the installation of ETCS or GSM-R.

The requirements of this TSI relating to train detection systems shall be respected when:

|  |  |
| --- | --- |
| (1) | upgrading the train detection system; |

|  |  |
| --- | --- |
| (2) | renewing the train detection system, provided that respecting the requirements of this TSI does not imply unwanted modifications or upgrades of other trackside or on-board systems; |

|  |  |
| --- | --- |
| (3) | renewing the train detection system, where this is required by the upgrade or renewal of trackside systems that use information from the train detection system; |

|  |  |
| --- | --- |
| (4) | removing Class B train protection systems where the train detection and train protection systems are integrated. |

In the migration phase care shall be taken to ensure that installing a TSI-compliant train detection system has a minimal negative impact on the existing non-TSI-compliant rolling stock.

To achieve this, it is recommended that the Infrastructure Manager selects a TSI-compliant train detection system that, at the same time, is compatible with the non-TSI-compliant rolling stock already operating on that infrastructure.

7.7.   Specific cases

7.7.1.   Introduction

The following special provisions are permitted in the specific cases below.

These specific cases belong to two categories: the provisions apply either permanently (case ‘P’) or temporarily, to be removed before 2040 (case ‘T’) or a date to be specified after the re-examination process defined in Article 13(5) of this Regulation (case ‘T2’).

The specific cases set out in points below shall be read in conjunction with the relevant points of Chapter 4 and/or specifications referenced there.

The specific cases replace the corresponding requirements set out in Chapter 4.

Where the requirements set out in the relevant point of Chapter 4 are not subject to a specific case, those requirements have not been duplicated in points below and continue to apply unmodified.

The assessment of the specific cases related to basic parameters 4.2.10 and 4.2.11 where indicated in the Notes column as ‘applicable to vehicles’ shall be assessed by Rolling Stock subsystem Notified Body.

All specific cases and their relevant dates shall be re-examined in the course of future revisions of the TSI with a view to limiting their technical and geographical scope based on an assessment of their impact on safety, interoperability, cross border services, TEN-T corridors, and the practical and economic impacts of retaining or eliminating them. Special account shall be given to availability of EU funding. The train detection systems and corresponding end dates shall be re-examined following Article 13(5) of this Regulation.

Specific cases shall be limited to the route or network where they are strictly necessary and taken account of through route compatibility procedures.

Partial Fulfilment

Notwithstanding the options allowed in this TSI, e.g. under point 7.3.2 or in subset 34, it is possible to deviate from this TSI provided that compliance with provisions of point 6.1.1.2 and the deviation fulfils one of the categories below and limited to the defined cases in the table underneath:

|  |  |
| --- | --- |
| (1) | Functions requiring upgrades of existing installations which would compromise the economic viability of a project regarding upgrades of already authorized hardware installed in the vehicles. |

|  |  |  |  |  |  |  |  |
| --- | --- | --- | --- | --- | --- | --- | --- |
| (2) | Functions included in system version 2.2 and 3.0 temporarily not implemented as long as the missing functions are not required for the intended area of use – provided such functions would be implemented at the earlier of the following conditions:   |  |  | | --- | --- | | (a) | If implementation of the missing function does not require authorization: at the next occasion when error correction is mandatory by virtue of table B1.1 row 1 and in any case not before 1.1.2026. |  |  |  | | --- | --- | | (b) | If implementation of the missing function requires authorization: at the next reauthorisation resulting from another change to the vehicle train protection (ETCS) system. |  |  |  | | --- | --- | | (c) | At the next upgrade to a higher system version of the ETCS train protection part. |   Until the implementation of full functionalities of system versions 2.2 and 3.0 these vehicles shall be declared as system version 2.1 and 2.2 respectively. |

|  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |

These reduced envelopes will be specified in SUBSET-153. | |  |  | | --- | --- | | Note: | Individual CR solutions which are excluded are published on the ERA website to temporarily develop the on-board envelopes up to 2.1 and up to 2.2. After the publication of the SUBSET-153, the vehicle shall update its products if not compliant to the consolidated specifications according to the transition clause on partial fulfilment listed in Table B.1. | | The following on-board functionalities impacting the ETCS on-board system version are excluded in the reduced on-board envelope up to 2.1:   |  |  | | --- | --- | |  | CR968;CR988; CR1238;CR1244;CR1302; CR1344;CR1346;CR1350; CR1359;CR1363;CR1367; CR1374;CR1375;CR1379; CR1397. |   The following on-board functionalities impacting the ETCS on-board system version are excluded in the reduced on-board envelope up to 2.2:   |  |  | | --- | --- | |  | CR968;CR988; CR1244;CR1302;CR1344; CR1346;CR1350;CR1359; CR1363;CR1367;CR1374; CR1375;CR1379;CR1397. | | | Subset 34: options available at subsystem level are also available at interoperability constituent level. | The functionality will not be required for the fully interoperable operations of the vehicle. | Interoperability constituents are not required to include functionalities related to electrical traction if these interoperability constituents are designed for vehicles equipped with catenary independent engines. | |
