2. SUBSYSTEM DEFINITION AND SCOPE

2.1. Introduction

▼M1

The Control-Command and Signalling Subsystems are defined in Annex II of Directive (EU) 2016/797 as:

(a) Trackside control-command and signalling as: ‘all the trackside equipment required to ensure safety and to command and control movements of trains authorised to travel on the network.’

(b) On-board control-command and signalling as ‘all the on-board equipment required to ensure safety and to command and control movements of trains authorised to travel on the network’.

▼B

The features of the Control-Command and Signalling Subsystems are:

(1) the functions that are essential for the safe control of railway traffic, and that are essential for its operation, including those required for degraded modes ( 5 );

(2) the interfaces;

(3) the level of performance required to meet the essential requirements.

2.2. Scope

▼M1

The Control-Command and Signalling Subsystem TSI specifies only those requirements which are necessary to assure the interoperability of the Union rail system and the compliance with the essential requirements ( 6 ).

▼B

The Control-Command and Signalling Subsystems include the following parts:

(1) train protection;

(2) voice radio communication;

(3) data radio communication;

(4) train detection.

The Class A train protection system is ETCS ( 7 ) whilst the Class A radio system is GSM-R.

For Class A train detection this TSI specifies only the requirements for the interface with other subsystems.

▼M1

Class B systems for the trans-European rail system network are a limited set of train protection and voice radio legacy systems that were already in use in the trans-European rail network before 20 April 2001.

Class B systems for other parts of the network of the rail system in the European Union are a limited set of train protection and voice radio legacy systems that were already in use in those networks before 1 July 2015.

The list of Class B systems is established in the European Union Agency for Railways technical document ‘List of CCS Class B systems, ERA/TD/2011-11, version 4.0.’

▼B

The requirements for the Control-Command and Signalling On-board Subsystem are specified in relation to Class A radio mobiles and train protection.

The requirements for the Control-Command and Signalling Trackside Subsystem are specified in relation to:

(1) the Class A radio network;

(2) Class A train protection;

(3) the interface requirements for train detection systems, to ensure their compatibility with rolling stock.

▼M1

All Control-Command and Signalling Subsystems, even where not specified in this TSI, shall be assessed according with Commission Implementing Regulation (EU) No 402/2013.

▼M1

2.3. Trackside Application Levels (ETCS)

The interfaces specified by this TSI define the means of data transmission to, and (where appropriate) from trains. The ETCS specifications referenced by this TSI provide application levels from which a trackside implementation may choose the means of transmission that meet its requirements.

This TSI defines the requirements for all application levels.

For the technical definition of the ETCS application levels see Annex A, 4.1 c.

▼B

3. THE ESSENTIAL REQUIREMENTS FOR THE CONTROL-COMMAND AND SIGNALLING SUBSYSTEMS

3.1. General

►M1 Directive (EU) 2016/797 ◄ requires that the subsystems and the interoperability constituents including interfaces meet the essential requirements set out in general terms in Annex III to the Directive.

The essential requirements are:

(1) Safety;

(2) Reliability and Availability;

(3) Health;

(4) Environmental Protection;

(5) Technical compatibility;

▼M1

(6) Accessibility.

▼B

The essential requirements for Class A systems are described below.

The requirements for Class B systems are the responsibility of the relevant Member State.

3.2. Specific Aspects of the Control-Command and Signalling Subsystems

▼M1

3.2.1. Safety

Every Control-Command and Signalling Subsystems project shall take the measures necessary to ensure that the level of risk of an incident occurring within the scope of the Control-Command and Signalling Subsystems, is not higher than the objective for the service.

To ensure that the measures taken to achieve safety do not jeopardise interoperability, the requirements of the basic parameter defined in point 4.2.1 (Control-Command and Signalling reliability, availability and safety characteristics relevant to interoperability) shall be respected.

For the ETCS Class A system the safety objective is apportioned between the Control-Command and Signalling On-board and Trackside Subsystems. The detailed requirements are specified in the basic parameter defined in point 4.2.1 (Control-Command and Signalling reliability, availability and safety characteristics relevant to interoperability). This safety requirement shall be met together with the availability requirements as defined in Point 3.2.2 (Reliability and Availability).

For the ETCS Class A system:

(a) the changes made by railway undertakings and infrastructure managers shall be managed in compliance with the processes and procedures of their safety management system;

(b) 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 Commission Implementing Regulation (EU) No 402/2013 ( 8 ), as referred to in Article 6(1)(a) of Directive (EU) 2016/798 of the European Parliament and of the Council ( 9 ).

Additionally the correct application of the risk management process as set out in Annex I of 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. The CSM Assessment Body shall be accredited or recognised according to the requirements in Annex II of Regulation (EU) No 402/2013 in the fields of ‘Control-command and signalling’ and ‘System safe integration’ as listed in item 5 ‘classification’ of ERADIS database entry for Assessment Bodies.

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

Whenever the specifications as referred to in Annex A, Table A 3 are used as an appropriate means to fully comply to the risk management process as set out in Annex I of the Commission 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 Annex A, Table A 3 shall be carried out by an Assessment Body accredited or recognized as specified in the section above instead of a CENELEC independent safety assessor.

▼B

3.2.2. Reliability and Availability

For the Class A system, the reliability and availability objectives are apportioned between the Control-Command and Signalling On-board and Trackside Subsystems. The detailed requirements are specified in the basic parameter defined in point 4.2.1 (Control-Command and Signalling safety characteristics relevant to interoperability).

▼M1

The level of risk caused by age and wear of constituents used within the subsystem shall be monitored. The requirements for maintenance stated in point 4.5 shall be respected.

▼B

3.2.3. Health

In accordance with Union legislation and with national legislation that is compatible with the Union legislation, care shall be taken to ensure that the materials used in and the design of the Control-Command and Signalling Subsystems do not constitute a health hazard to persons having access to them.

3.2.4. Environmental Protection

In accordance with Union legislation and with national legislation that is compatible with Union legislation:

(1) the Control-Command and Signalling equipment, if subjected to excessive heat or fire, shall not exceed limits for the emission of fumes or gases which are harmful to the environment;

(2) the Control-Command and Signalling equipment shall not contain substances which may abnormally contaminate the environment during their normal use;

(3) the Control-Command and Signalling equipment shall be subject to the Union legislation in force controlling the limits to the emission of and the susceptibility to electromagnetic interference along the boundaries of railway property;

(4) the Control-Command and Signalling equipment shall comply with existing regulations on noise pollution;

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 appropriate 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 performances 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 ►M1 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 the specifications referred to in Annex A and these texts also state how the functions are classified.

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

4.1.3. Parts of Control-command and Signalling Subsystems

According to point 2.2 (Scope) the Control-Command and Signalling Subsystems can be subdivided in parts.

4.2. Functional and technical specifications of the Subsystems

4.2.1. ►M1 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 (Availability and Reliability).

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 rate (THR) is 10– 9 h– 1 for random failures, for on-board ETCS and for trackside ETCS. See Annex A 4.2.1 a.

To achieve interoperability, the on-board ETCS shall fully respect all requirements specified in Annex A 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.

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 4.5 (Maintenance rules) shall be respected.

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

▼M1

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 point 6.2.1, 6.2.2, 6.2.3, 6.2.4);

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

6.1.1.2. Essential requirements fulfilled by National Rules

In certain cases, some of the essential requirements may be met by national rules, because of:

(1) the use of Class B systems;

(2) open points in the TSI;

(3) non-application of TSIs (derogations) under Article 7 of Directive (EU) 2016/797;

(4) specific cases described in point 7.6.

In such cases, assessment of conformity with those rules shall be carried out under the responsibility of the Member States concerned according to notified procedures. See point 6.4.2.

6.1.1.3. Partial fulfilment of TSI requirements

With regard to checking if essential requirements are fulfilled through compliance with the basic parameters, and without prejudice to the obligations set out in Chapter 7 of this TSI, control-command and signalling interoperability constituents and subsystems that do not implement all functions, performance and interfaces as specified in Chapter 4 (including the specifications referred to in Annex A), can obtain EC certificates of conformity or, respectively, certificates of verification, under the following conditions for issuing and using the certificates:

(1) The applicant for EC verification of a trackside control-command and signalling subsystem is responsible for deciding which functions, performance and interfaces need to be implemented to meet the objectives for the service and to ensure that no requirements contradicting or exceeding the TSIs are exported to the on-board control-command and signalling subsystems.

(2) The operation of an on-board control-command and signalling subsystem, that does not implement all functions, performance and interfaces specified in this TSI, may be subject to conditions and limits of use due to compatibility and/or safe integration with trackside control-command and signalling subsystems. Without prejudice to the tasks of a Notified Body described in respective Union legislation and related documents the applicant for EC verification is responsible for ensuring that the technical file provides all the information ( 13 ) that an operator needs to identify such conditions and limits of use.

(3) The authorising entity may refuse for duly justified reasons the authorisation for placing in service or on the market, or place conditions and limits of use on the operation, of control-command and signalling subsystems that do not implement all functions, performance and interfaces specified in this TSI.

If a control-command and signalling interoperability constituent or subsystem does not implement all functions, performance and interfaces specified in this TSI, the provisions of point 6.4.3 shall apply.

6.1.2. Principles for testing ETCS and GSM-R

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 and GSM-R (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 tests 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 and GSM-R 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.

6.1.2.4. Requirements for ETCS System Compatibility

The Agency shall set up and manage in a technical document the set of checks to demonstrate the technical compatibility of an on-board subsystem with the trackside subsystem.

Infrastructure Managers, with the support of the ETCS suppliers for their network, shall submit to the Agency the definition of the necessary checks (as defined in 4.2.17) on their network by 16 January 2020 at the latest.

Infrastructure Managers shall classify the ETCS lines according to ESC types in RINF.

Infrastructure Managers shall submit to the Agency any changes on the referred checks for their network. The Agency shall update the technical document within 5 working days.

6.1.2.5. Requirements for Radio System Compatibility

The Agency shall set up and manage in a technical document the set of checks to demonstrate the technical compatibility of an on-board subsystem with the trackside subsystem.

Infrastructure Managers, with the support of the GSM-R suppliers for their network, shall submit to the Agency the definition of the necessary checks (as defined in 4.2.17) on their network by 16 January 2020 at the latest.

Infrastructure Managers shall classify their lines according to RSC types for voice and, if applicable, ETCS data in RINF.

Infrastructure Managers shall submit to the Agency any changes on the referred checks for their network. The Agency shall update the technical document within 5 working days.

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 ►M1 Article 10(1) and Article 9(2) 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 ( 14 ).

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 Interoperability Constituent, the manufacturer or his representative may choose module CA.

The modules are described in detail in the Commission Decision 2010/713/EU ( 15 ).

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 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.

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;

▼M1

(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 ( 16 ) and the standards referred to in Annex A, Table A 4 to carry out tests with the use of the test architecture and the procedures specified in Annex A 4.2.2.c.

▼B

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. The Specific Transmission Module (STM)

Each Member State shall be responsible for verifying that STMs conform to its national requirements.

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

6.3.1. Assessment procedures for Control-Command and Signalling Subsystems

This Chapter deals with the ‘EC’ declaration of verification for the Control-Command and Signalling On-board Subsystem and the ‘EC’ declaration of verification for the Control-Command and Signalling Trackside Subsystem.

At the request of the applicant the Notified Body shall carry out an ‘EC’ verification of a Control-Command and Signalling On-board or Trackside Subsystem in accordance with Annex IV to Directive (EU) 2016/797.

The applicant shall draw up the ‘EC’ declaration of verification for the Control-Command and Signalling On-board or Trackside Subsystem in accordance with Article 15(1) and Article 15(9) of Directive (EU) 2016/797.

The content of the ‘EC’ declaration of verification shall conform to Article 15(9) of Directive (EU) 2016/797.

The assessment procedure shall be carried out using the modules specified in point 6.3.2 (Modules for Control-Command and Signalling Subsystems).

The ‘EC’ declarations of verification for a Control-Command and Signalling On-board Subsystem and of a Control-Command and Signalling Trackside Subsystem, together with the certificates of conformity, shall be deemed sufficient to ensure that the subsystems are compatible under the conditions specified in this TSI.
