   Having regard to Directive 2008/57/EC of the European Parliament and the Council of 17 June 2008 on the interoperability of the rail system within the Community (1), and in particular Article 6(1) thereof,
   Whereas:
   
               (1)
            
            
               In accordance with Article 2(e) and Annex II to Directive 2008/57/EC, the rail system is subdivided into structural and functional subsystems, including an energy subsystem.
            
         
               (2)
            
            
               By Decision C(2006) 124 final of 9 February 2006, the Commission gave a mandate to the European Railway Agency (the Agency) to develop technical specifications for interoperability (TSIs) under Directive 2001/16/EC of the European Parliament and of the Council of 19 March 2001 on the interoperability of the trans-European conventional rail system (2). Under the terms of that mandate, the Agency was requested to draw up the draft TSI related to the energy subsystem of the conventional rail system.
            
         
               (3)
            
            
               Technical specifications for interoperability (TSI) are specifications adopted in accordance with the Directive 2008/57/EC. The TSI in Annex covers the energy subsystem in order to meet the essential requirements and ensure the interoperability of the rail system.
            
         
               (4)
            
            
               The TSI in Annex should refer to Commission Decision 2010/713/EU of 9 November 2010 on modules for the procedures for assessment of conformity, suitability for use and EC verification to be used in the technical specifications for interoperability adopted under Directive 2008/57/EC of the European Parliament and of the Council (3).
            
         
               (5)
            
            
               In accordance with Article 17(3) of Directive 2008/57/EC, Member States are to notify to the Commission and other Member States the conformity assessment and verification procedures to be used for the specific cases, as well as the bodies responsible for carrying out these procedures.
            
         
               (6)
            
            
               The TSI in Annex should be without prejudice to the provisions of other relevant TSIs which may be applicable to energy subsystems.
            
         
               (7)
            
            
               The TSI in Annex should not impose the use of specific technologies or technical solutions except where this is strictly necessary for the interoperability of the rail system within the Union.
            
         
               (8)
            
            
               In accordance with Article 11(5) of Directive 2008/57/EC, the TSI in Annex should allow, for a limited period of time, for interoperability constituents to be incorporated into subsystems without certification if certain conditions are met.
            
         
               (9)
            
            
               To continue to encourage innovation and to take into account the experience acquired, the TSI in Annex should be subject to periodic revision.
            
         
               (10)
            
            
               The measures provided for in this Decision are in conformity with the opinion of the Committee established in accordance with Article 29(1) of Directive 2008/57/EC,
            
         HAS ADOPTED THIS DECISION:
   Article 1
   A Technical Specification for Interoperability (TSI) relating to the energy subsystem of the trans-European conventional railway, is hereby adopted by the Commission.
   The TSI shall be as set out in the Annex to this Decision.
   Article 2
   This TSI shall be applicable to all new, upgraded or renewed infrastructure of the trans-European conventional rail system as defined in Annex I to Directive 2008/57/EC.
   Article 3
   The procedures for assessment of conformity, suitability for use and EC verification set out in Chapter 6 of the TSI in Annex shall be based on the modules defined in Decision 2010/713/EU.
   Article 4
   1.   During a transition period of 10 years, it shall be permissible to issue an EC certificate of verification for a subsystem that contains interoperability constituents not holding an EC Declaration of conformity or suitability for use, on the condition that the provisions set out in Section 6.3 of the Annex are met.
   2.   The production or upgrade/renewal of the subsystem with use of the non-certified interoperability constituents must be completed within the transition period, including the placing in service.
   3.   During the transition period Member States shall ensure that:
   
               (a)
            
            
               the reasons for non-certification of the interoperability constituent are properly identified in the verification procedure referred to in paragraph 1;
            
         
               (b)

         2.   DEFINITION AND SCOPE OF THE SUBSYSTEM
         2.1.   Definition of the energy subsystem
         
         The Energy TSI specifies those requirements which are necessary to assure the interoperability of the rail system. This TSI covers all fixed installations, DC or AC that are required to supply, with respect to the essential requirements, traction energy to a train.
         The energy subsystem also includes the definition and quality criteria for interaction between a pantograph and the overhead contact line. As the ground level conductor rail (third rail) and contact shoe system is not a ‘target’ system, this TSI does not describe the characteristics or functionality of such a system.
         
            Figure 1
         
         
            Energy subsystem
         
         
            
         The energy subsystem consists of:
         (a)   substations: connected on the primary side to the high-voltage grid, with transformation of the high-voltage to a voltage and/or conversion to a power supply system suitable for the trains. On the secondary side, substations are connected to the railway contact line system;
         (b)   sectioning locations: electrical equipment located at intermediate locations between substations to supply and parallel contact lines and to provide protection, isolation and auxiliary supplies;
         (c)   separation sections: equipment required to provide the transition between electrically different systems or between different phases of the same electrical system;
         (d)   contact line system: a system that distributes the electrical energy to the trains running on the route and transmits it to the trains by means of current collectors. The contact line system is also equipped with manually or remotely controlled disconnectors which are required to isolate sections or groups of the contact line system according to operational necessity. Feeder lines are also part of the contact line system;
         (e)   return circuit: all conductors which form the intended path for the traction return current and which are additionally used under fault conditions. Therefore, so far as this aspect is concerned, the return circuit is part of the energy subsystem and has an interface with the infrastructure subsystem.
         In addition, according to the Directive 2008/57/EC, the energy subsystem includes:
         (f)   on-board parts of the electric consumption measuring equipment— for measurement of electric energy taken from or returned to (during regenerative braking) the contact line by the vehicle, supplied from the external electric traction system. The equipment is integrated into and put into service with the traction unit, and is in the scope of the conventional rail locomotives and passenger rolling stock TSI (CR LOC&PAS).
         The Directive 2008/57/EC also foresees that the current collectors (pantographs), which transmit electrical energy from the overhead contact line system to the vehicle, are in the rolling stock subsystem. They are installed and are integrated into and put into service with the rolling stock and are in the scope of CR LOC&PAS TSI.
         However, the parameters relating to the quality of current collection are specified in CR ENE TSI.
         2.1.1.   Power supply
         
         The power supply system has to be designed such that every train will be supplied with the necessary power. Therefore, the supply voltage, current draw of each train and the operating schedule are important aspects for performance.
         As with any electrical device, a train is designed to operate correctly with a nominal voltage and a nominal frequency applied at its terminals, i.e. the pantograph(s) and wheels. Variations and limits of these parameters need to be defined in order to assure the anticipated train performance.
         Modern, electrically powered trains are often capable of using regenerative braking to return energy to the power supply, reducing power consumption overall. The power supply system can be designed to accommodate such regenerative braking energy.
         In any power supply, short-circuits and other fault conditions may occur. The power supply needs to be designed so that the controls detect these faults immediately and trigger measures to remove the short-circuit current and isolate the affected part of the circuit. After such events, the power supply has to be able to restore supply to all installations as soon as possible in order to resume operations.
         2.1.2.   Overhead contact line and pantograph
         
         A compatible geometry of the overhead contact line to the pantograph is an important aspect of interoperability. As far as geometrical interaction is concerned, the height of the contact wire above the rails, the variation in contact wire height, the lateral deviation under wind pressure and the contact force have to be specified. The geometry of the pantograph head is also fundamental to assure good interaction with the overhead contact line, taking into account vehicle sway.
         In order to support interoperability of European networks, the pantographs specified in CR LOC&PAS TSI are the target.
         The interaction between an overhead contact line and a pantograph represents a very important aspect in establishing reliable power transmission without undue disturbances to railway installations and the environment. This interaction is mainly determined by:
         
                     (a)
                  
                  
                     static and aerodynamic effects dependent upon the nature of the pantograph contact strips and the design of the pantograph, the shape of the vehicle on which the pantograph(s) is (are) mounted and the position of the pantograph on the vehicle,
                  
               
                     (b)
                  
                  
                     the compatibility of the contact strip material with the contact wire,
                  
               
                     (c)
                  
                  
                     the dynamic characteristics of the overhead contact line and pantograph(s) for single unit or multiple unit trains,
                  
               
                     (d)
                  
                  
                     the number of pantographs in service and the distance between them, since each pantograph can interfere with the others on the same overhead contact line section.
                  
               2.2.   Interfaces with other subsystems and within the subsystem
         
         2.2.1.   Introduction
         
         The energy subsystem interfaces with some of the other subsystems of the rail system in order to achieve the envisaged performance. These are listed below:
         2.2.2.   Interfaces concerning power supply
         
         
                     (a)
                  
                  
                     Voltage and frequency and their permissible ranges interface with the rolling stock subsystem.
                  
               
                     (b)
                  
                  
                     The power installed on the lines and the specified power factor determines the performance of the rail system and interfaces with the rolling stock subsystem.
                  
               
                     (c)
                  
                  
                     Regenerative braking reduces energy consumption and interfaces with the rolling stock subsystem.
                  
               
                     (d)
                  
                  
                     Electrical fixed installations and on-board traction equipment need to be protected against short circuits. Circuit breaker tripping in substations and on trains has to be coordinated. Electrical protection interfaces with the rolling stock subsystem.
                  
               
                     (e)
                  
                  
                     Electrical interference and harmonic emissions interface with the rolling stock and control-command and signalling subsystems.
                  
               
                     (f)
                  
                  
                     The current return circuit has some interfaces with control-command and signalling and infrastructure subsystems.
                  
               2.2.3.   Interfaces concerning overhead line equipment and pantographs and their interaction
         
         
                     (a)
                  
                  
                     The contact wire gradient and rate of change of gradient needs special attention in order to avoid loss of contact and excessive wear. The contact wire height and gradient interfaces with the infrastructure and rolling stock subsystems.
                  
               
                     (b)
                  
                  
                     Vehicle and pantograph sway interfaces with the infrastructure subsystem.
                  
               
                     (c)
                  
                  
                     The quality of current collection depends on the number of pantographs in service, their spacing and other traction-unit-specific details. The arrangement of pantographs interfaces with the rolling stock subsystem.
                  
               2.2.4.   Interfaces concerning phase and system separation sections
         
         
                     (a)
                  
                  
                     To pass transitions between different power supply system and phase separation sections, without bridging, the number and arrangement of pantographs on trains shall be stipulated. This interfaces with the rolling stock subsystem.
                  
               
                     (b)
                  
                  
                     To pass transitions of power supply system and phase separation sections, without bridging, control of train current is required. This interfaces with the control-command and signalling subsystem.
                  
               
                     (c)
                  
                  
                     When passing through power supply system separation sections, lowering of pantograph(s) may be required. This interfaces with the control-command and signalling subsystem.
                  
               3.   ESSENTIAL REQUIREMENTS

               4.   CHARACTERISATION OF THE SUBSYSTEM
         4.1.   Introduction
         
         The rail system, to which the Directive 2008/57/EC applies, and of which the subsystem is a part, is an integrated system whose consistency shall be verified. This consistency must be checked, in particular, with regard to the specifications of the subsystem, its interfaces vis-à-vis the system in which it is integrated, as well as the operating and maintenance rules.
         The functional and technical specifications of the subsystem and its interfaces, described in chapters 4.2 and 4.3, do not impose the use of specific technologies or technical solutions, except where this is strictly necessary for the interoperability of the rail network. But innovative solutions for interoperability may require new specifications and/or new assessment methods. In order to allow technological innovation, these specifications and assessment methods shall be developed by the process described in chapters 6.1.3 and 6.2.3.
         Taking account of all the applicable essential requirements, the energy subsystem is characterised by the specifications set out in clauses 4.2 to 4.7. A list of parameters relevant for the energy subsystem which shall be collected in the Register of infrastructure is in Annex C to this TSI.
         Procedures for the EC verification of the energy subsystem are indicated in clause 6.2.4 and Annex B, Table B.1, to this TSI.
         For Specific Cases, see Chapter 7.5;
         Where reference is made to EN standards, any variations called ‘national deviations’ or ‘special national conditions’ in the EN do not apply.
         4.2.   Functional and technical specifications of the subsystem
         
         4.2.1.   General provisions
         
         The performance to be achieved by the Energy subsystem shall correspond to the relevant performance of the rail system, with respect to:
         
                     —
                  
                  
                     the maximum line speed, type of train, and
                  
               
                     —

                     DC 1,5 kV.
                  
               Nominal voltage and frequency shall be listed in the Register of infrastructure (see Annex C).
         4.2.4.   Parameters relating to supply system performance
         
         The design of the energy subsystem is determined by the line speed for the planned services and the topography.
         Therefore the following parameters have to be taken in consideration:
         
                     —

                     —
                  
                  
                     the mean useful voltage.
                  
               4.2.4.1.   Maximum train current
         
         The Infrastructure Manager shall declare the maximum train current in the Register of infrastructure (see Annex C).
         The energy subsystem design shall ensure the ability of the power supply to achieve the specified performance and permit the operation of trains with a power less than 2 MW without current limitation as described in clause 7.3 of EN50388:2005.

         4.2.5.   Continuity of power supply in case of disturbances in tunnels
         
         The power supply and the overhead contact line system shall be designed to enable continuity of operation in case of disturbances in tunnels. This shall be achieved by sectioning overhead contact line in accordance with clause 4.2.3.1 of the SRT TSI.
         4.2.6.   Current capacity, DC systems, trains at standstill
         
         The overhead contact line of DC systems shall be designed to sustain 300 A (for a 1.5 kV supply system) and 200 A (for a 3 kV supply system), per pantograph when the train is at standstill.
         This shall be achieved using a static contact force as defined in clause 7.1 of EN50367:2006.
         Where the overhead contact line has been designed to sustain higher values for maximum current at standstill, this shall be declared by the Infrastructure Manager in the Register of infrastructure (see Annex C).
         The OCL shall be designed taking into account the temperature limits in accordance with EN50119:2009 clause 5.1.2.
         4.2.7.   Regenerative braking
         
         AC power supply systems shall be designed to permit the use of regenerative braking as a service brake, able to exchange power seamlessly either with other trains or by any other means.

         4.2.9.   Harmonics and dynamic effects for AC systems
         
         The CR energy subsystem and rolling stock must be able to work together without interference problems, such as over-voltages and other phenomena described in EN50388:2005 clause 10.
         4.2.10.   Harmonic emissions towards the power utility
         
         Harmonic emissions towards the power utility shall be dealt with by the Infrastructure Manager taking into account European or national standards and the requirements of the power utility.
         No conformity assessment is required within this TSI.
         4.2.11.   External electromagnetic compatibility
         
         External electromagnetic compatibility is not a specific characteristic of the rail network. Energy supply installations shall comply with the Essential Requirements of the EMC Directive 2004/108/EC.
         No conformity assessment is required within this TSI.
         4.2.12.   Protection of the environment
         
         Protection of the environment is covered by other European legislation concerning the assessment of the effects of certain projects on the environment.
         No conformity assessment is required within this TSI.
         4.2.13.   Geometry of the overhead contact line
         
         Overhead contact line shall be designed for use by pantographs with the head geometry specified in the CR LOC&PAS TSI clause 4.2.8.2.9.2.
         The contact wire height, gradient of the contact wire in relation to the track and the lateral deviation of the contact wire under the action of a cross-wind all govern the interoperability of the rail network.
         4.2.13.1.   Contact wire height
         
         The nominal contact wire height shall be in the range of 5,00 – 5,75 m. For the relation between the contact wire heights and pantograph working heights see EN50119:2009 figure 1.
         The contact wire height may be lower in cases related to gauge (like bridges, tunnels). The minimum contact wire height shall be calculated in accordance with EN50119:2009 clause 5.10.4.
         The contact wire may be higher in cases e.g. level crossings, loading areas, etc. In these cases the maximum design contact wire height shall not be greater than 6,20 m.
         Taking into account tolerances and uplift in accordance with EN50119:2009 figure 1, the maximum contact wire height shall not be greater than 6,50 m.
         The nominal contact wire height shall be listed in the Register of infrastructure (see Annex C).

         The variation in contact wire height shall fulfil the requirements imposed by EN50119:2009 clause 5.10.3.
         The contact wire gradient specified in EN50119:2009 clause 5.10.3 may be exceeded on an exceptional basis where a series of restrictions on the contact wire height e.g. level crossings, bridges, tunnels, prevents compliance; in this case when applying the requirements of clause 4.2.16, only the requirement related to the maximum contact force shall be complied with.
         4.2.13.3.   Lateral deviation
         
         The maximum permissible lateral deviation of the contact wire normal to the design track centre line under the action of cross wind is given in Table 4.2.13.3.

         No part of the energy subsystem shall enter the mechanical kinematic pantograph gauge (see Annex E figure E.2) except for the contact wire and steady arm.
         The mechanical kinematic pantograph gauge for interoperable lines is determined using the method shown in Annex E clause E.2 and the pantograph profiles defined in CR LOC&PAS TSI clause 4.2.8.2.9.2.
         This gauge shall be calculated using a kinematic method, with values:
         
                     —
                  
                  
                     for the pantograph sway — epu — of 0,110 m at the lower verification height — h'u ≤ 5,0 m, and

         4.2.16.   Dynamic behaviour and quality of current collection
         
         The overhead contact line shall be designed in accordance with the requirements for dynamic behaviour. Contact wire uplift at the design speed shall comply with the stipulations in Table 4.2.16.
         The quality of current collection has a fundamental impact on the life of a contact wire and shall, therefore, comply with agreed and measurable parameters.
         Compliance with the requirements on dynamic behaviour shall be verified by assessment of:

               For definitions, values and test methods refer to EN50317:2002 and EN50318:2002.
         S0 is the calculated, simulated or measured uplift of the contact wire at a steady arm, generated in normal operating conditions with one or more pantographs with a mean contact force Fm at the maximum line speed. When the uplift of the steady arm is physically limited due to the overhead contact line design, it is permissible for the necessary space to be reduced to 1,5 S0 (refer to EN50119:2009 clause 5.10.2).
         Maximum force (Fmax) on an open route is usually within the range of Fm plus three standard deviations σmax; higher values may occur at particular locations and are given in EN50119:2009, Table 4 clause 5.2.5.2.
         For rigid components such as section insulators in overhead contact line systems, the contact force can increase up to a maximum of 350 N.
         4.2.17.   Pantograph spacing
         
         The overhead contact line shall be designed for a minimum of two pantographs operating adjacently, having a minimum spacing centre line to centre line of the pantograph head as set out in Table 4.2.17:

                     —
                  
                  
                     the distance design type (A or B or C) for the OCL according to Table 4.2.17,
                  
               
                     —
                  
                  
                     the minimum spacing between adjacent pantographs below those shown in the Table 4.2.17,
                  
               
                     —
                  
                  
                     the number of pantographs above two, for which the line has been designed.
                  
               4.2.18.   Contact wire material
         
         The combination of contact wire material and contact strip material has a strong impact on the wear on both sides.
         Permissible materials for contact wires are copper and copper-alloy (excluding copper-cadmium-alloys). The contact wire shall comply with the requirements of EN50149:2001 clauses 4.1, 4.2 and 4.5 to 4.7 (excluding Table 1).
         For AC lines the contact wire shall be designed to permit the use of plain carbon contact strips (CR LOC&PAS TSI clause 4.2.8.2.9.4.2). Where the IM accepts other contact strip material an entry shall be made in the Register of infrastructure (see Annex C).
         For DC lines the contact wire shall be designed to accept contact strip materials in accordance with CR LOC&PAS TSI clause 4.2.8.2.9.4.2.
         4.2.19.   Phase separation sections
         
         The design of phase separation sections shall ensure that trains can move from one section to an adjacent one without bridging the two phases. Power consumption shall be brought to zero according to EN50388:2005 clause 5.1.
         Adequate means (except the short separation section as in Annex F — fig. F.1) shall be provided to allow a train that is stopped within the phase separation section to be restarted. The neutral section shall be connectable to the adjacent sections by remotely controlled disconnectors.
         The design of separation sections shall normally adopt solutions as described in EN50367:2006 Annex A.1 or in Annex F to this TSI. Where an alternative solution is proposed, it shall be demonstrated that the alternative is at least as reliable.
         Information on the design of phase separation sections and permissible configuration of raised pantographs shall be provided in the Register of infrastructure (see Annex C).
         4.2.20.   System separation sections
         
         4.2.20.1.   General
         
         The design of system separation sections shall ensure that vehicles can move from one power supply system to an adjacent different power supply system without bridging the two systems. A system separation between AC and DC system needs additional measures to be taken in the return circuit as defined in EN50122-2:1998, clause 6.1.1.
         There are two methods for traversing system separation sections:
         
                     (a)
                  
                  
                     with pantograph raised and touching the contact wire,
                  
               
                     (b)
                  
                  
                     with pantograph lowered and not touching the contact wire.
                  
               The neighbouring Infrastructure Managers shall agree either (a) or (b) according to the prevailing circumstances. The method to be adopted shall be recorded in the Register of infrastructure (see Annex C).
         4.2.20.2.   Pantographs raised
         
         If system separation sections are traversed with pantographs raised to the contact wire, their functional design is specified as follows:
         
                     —
                  
                  
                     the geometry of different elements of the overhead contact line shall prevent pantographs short-circuiting or bridging both power systems,
                  
               
                     —
                  
                  
                     provision shall be made in the energy subsystem to avoid bridging of both adjacent power supply systems should the opening of the on-board circuit breaker(s) fail,
                  
               
                     —
                  
                  
                     variation in contact wire height along the entire separation section shall fulfil requirements set in EN50119:2009 clause 5.10.3.
                  
               The pantograph arrangements that are permitted to traverse the system separation with pantographs raised shall be provided in the Register of infrastructure (see Annex C).
         4.2.20.3.   Pantographs lowered
         
         This option shall be chosen if the conditions of operation with pantographs raised cannot be met.
         If a system separation section is traversed with pantographs lowered, it shall be designed so as to avoid the bridging by an unintentionally raised pantograph. Equipment shall be provided to switch off both power supply systems should a pantograph remain raised, e.g. by detection of short circuits.
         4.2.21.   Electric energy consumption measuring equipment
         
         As it is specified in clause 2.1 of this TSI, requirements for the on-board electric energy consumption measuring equipment are set out in the CR LOC&PAS TSI.
         If an electric energy consumption measuring equipment is installed, it shall be compatible with CR LOC&PAS TSI clause 4.2.8.2.8. This equipment can be used for billing purposes and the data provided by it shall be accepted for billing in all Member States.
         4.3.   Functional and technical specifications of the interfaces
         
         4.3.1.   General requirements
         
         From the standpoint of technical compatibility, the interfaces are listed in subsystem order as follows: rolling stock, infrastructure, control and command and signalling, traffic operation and management. They also include indications to safety in railway tunnels TSI (SRT TSI).

         The interface for power control at phase and system separation sections is an interface between the energy and the rolling stock subsystems. However, it is controlled via the control-command and signalling subsystem and consequently the interface is specified in the CR CCS TSI and the CR LOC & PAS TSI.
         Since the harmonic currents generated by rolling stock affect the control-command and signalling subsystem through the energy subsystem, this subject is dealt within the control-command and signalling subsystem.

         In the case of products placed on the market before the publication of this TSI, the type is considered to have been approved and therefore EC type examination (module CB) is not necessary, provided that the manufacturer demonstrates that tests and verification of interoperability constituents have been considered successful for previous applications under comparable conditions and are in conformity with the requirements of this TSI. In this case these assessments shall remain valid in the new application. If it is not possible to demonstrate that the solution is positively proven in the past, the procedure for ICs placed on the EU market after publication of this TSI applies.
         6.1.3.   Innovative solutions for Interoperability Constituents
         
         If an innovative solution is proposed for an interoperability constituent as defined in clause 5.2, the manufacturer or his authorised representative established within the Community shall state the deviations from the relevant clause of this TSI and submit them to the Commission for analysis.
         In case the analysis results in a favourable opinion, the appropriate functional and interface specifications for the constituent and the assessment method will be developed under the authorisation of the Commission.
         The appropriate functional and interface specifications and the assessment methods so produced shall be incorporated in the TSI by the revision process.
         By the notification of a decision of the Commission, taken in accordance with Article 29 of the Directive, the innovative solution may be permitted to be used before being incorporated into the TSI by the revision process.

         The assessment of the dynamic behaviour and the quality of the current collection involves the overhead contact line (energy subsystem) and the pantograph (rolling stock subsystem).
         A new design of overhead contact line shall be assessed by simulation according to EN50318:2002 and by measurement of a test section of the new design according to EN50317:2002.
         For the purposes of simulation and analysis of the results, representative features (for example tunnels, crossovers, neutral sections etc.) shall be taken into account.
         The simulations shall be made using at least two different TSI compliant (2) types of pantograph for the appropriate speed (3) and supply system, up to the design speed of the proposed Interoperability Constituent overhead contact line.
         It is permitted to perform the simulation using types of pantograph that are under the process of IC certification, provided that they fulfil the other requirements of CR LOC&PAS TSI.
         The simulation shall be performed for single pantograph and multiple pantographs with spacing according to the requirements set in clause 4.2.17.
         In order to be acceptable, the simulated current collection quality shall be in accordance with clause 4.2.16 for uplift, mean contact force and standard deviation for each of the pantographs.
         If the simulation results are acceptable, a site dynamic test with a representative section of the new overhead contact line shall be undertaken.
         For the above mentioned site test, one of the two types of the pantograph chosen for the simulation, shall be installed on a rolling stock that allows the appropriate speed on the representative section.
         The tests shall be performed at least for the worst case arrangements of the pantographs derived from the simulations and shall fulfil the requirements set out in clause 4.2.17.
         Each pantograph shall produce a mean contact force up to the envisaged design speed of the OCL under test as required by clause 4.2.15.
         In order to be acceptable, the measured current collection quality shall be in accordance with clause 4.2.16, for uplift, and either mean contact force and standard deviation or percentage of arcing.
         If all the above assessments are passed successfully, the tested overhead contact line design shall be considered to be compliant and may be used on lines where the characteristics of the design are compatible.
         Assessment of dynamic behaviour and quality of current collection for interoperability constituent pantograph are set out in clause 6.1.2.2.6 of CR LOC&PAS TSI
         6.1.4.2.   Assessment of current at standstill
         
         The conformity assessment shall be carried out in accordance with EN50367:2006, Annex A.4.1.

         6.2.3.   Innovative solutions
         
         If the subsystem includes an innovative solution as defined in clause 4.1, the applicant shall state the deviation from the relevant clauses of the TSI and submit them to the Commission.
         In case of favourable opinion, the appropriate functional and interface specifications, and the assessment methods for this solution will be developed.
         The appropriate functional and interface specifications and the assessment methods so produced shall then be incorporated in the TSI by the revision process. By the notification of a decision of the Commission, taken in accordance with Article 29 of the Directive, the innovative solution may be permitted to be used before being incorporated into the TSI by the revision process.
         6.2.4.   Particular assessment procedures for Subsystem
         
         6.2.4.1.   Assessment of mean useful voltage
         
         The assessment shall be carried out in accordance with EN50388:2005, clauses 14.4.1, 14.4.2 (simulation only) and 14.4.3.
         6.2.4.2.   Assessment of regenerative braking
         
         The assessment for AC power supply fixed installations shall be carried out according to EN50388:2005, clause 14.7.2.
         The assessment for DC power supply shall be carried out by a design review.
         6.2.4.3.   Assessment of electrical protection coordination arrangements
         
         The assessment shall be carried out for design and operation of substations in accordance with EN50388:2005 clause 14.6.
         6.2.4.4.   Assessment of harmonic and dynamic effects for AC systems
         
         The assessment, based on a compatibility study, shall be conducted according to EN50388:2005 clause 10.3 taking into account over-voltages given in EN 50388:2005 clause 10.4.
         6.2.4.5.   Assessment of dynamic behaviour and quality of current collection (integration into a subsystem)
         
         If the overhead contact line to be installed on a new line is certificated as an Interoperability Constituent, measurements of the interaction parameters in accordance with EN50317:2002 shall be used to check the correct installation.
         These measurements shall be carried out with an Interoperability Constituent pantograph, exhibiting the mean contact force characteristics as required by clause 4.2.15 of this TSI for the envisaged design speed of the overhead contact line.
         The main goal of this test is to identify construction errors but not to assess the design in principle.
         The installed overhead contact line can be accepted if the measurement results comply with the requirements in clause 4.2.16 for uplift, and either mean contact force and standard deviation or percentage of arcing.
         Assessment of dynamic behaviour and quality of current collection for integration of the pantograph into rolling stock subsystem are set out in clause 6.2.2.2.14 of CR LOC&PAS TSI
         6.2.4.6.   Assessment of maintenance plan
         
         The assessment shall be carried out by verifying the existence of the maintenance.
         The Notified Body is not responsible for assessing the suitability of the detailed requirements set out in the plan.
         6.3.   Subsystem containing Interoperability Constituents not holding an EC declaration
         
         6.3.1.   Conditions
         
         During the transition period provided in Article 4 of this Decision, a Notified Body is permitted to issue an EC certificate of verification for a subsystem, even if some of the interoperability constituents incorporated within the subsystem are not covered by the relevant EC declarations of conformity and/or suitability for use according to this TSI, if the following criteria are complied with:
         
                     —
                  
                  
                     the conformity of the subsystem has been checked against the requirements of Chapter 4 and in relation to Chapter 6.2. to 7 (except ‘Specific Cases’) of this TSI by the Notified Body.
                     Furthermore the conformity of the ICs to Chapters 5 and 6.1 does not apply, and
                  
               
                     —
                  
                  
                     the interoperability constituents, which are not covered by the relevant EC declaration of conformity and/or suitability for use, have been used in a subsystem already approved and put in service in at least one of the Member State before the entry in force of this TSI.
                  
               EC Declarations of conformity and/or suitability for use shall not be drawn up for the interoperability constituents assessed in this manner.
         6.3.2.   Documentation
         
         The EC certificate of verification of the subsystem shall indicate clearly which interoperability constituents have been assessed by the Notified Body as part of the subsystem verification.
         The EC declaration of verification of the subsystem shall indicate clearly:
         
                     —
                  
                  
                     which interoperability constituents have been assessed as part of the subsystem,
                  
               
                     —
                  
                  
                     confirmation that the subsystem contains the interoperability constituents identical to those verified as part of the subsystem,
                  
               
                     —
                  
                  
                     for those interoperability constituents, the reason(s) why the manufacturer did not provide an EC declaration of conformity and/or suitability for use before its incorporation into the subsystem, including the application of national rules notified under Article 17 of Directive 2008/57/EC.
                  
               6.3.3.   Maintenance of the subsystems certified according to 6.3.1
         
         During the transition period as well as after the transition period has ended, until the subsystem is upgraded or renewed (taking into account the decision of Member State on application of TSIs), the interoperability constituents which do not hold an EC Declaration of conformity and/or suitability for use and of the same type are permitted to be used as maintenance related replacements (spare parts) for the subsystem, under the responsibility of the body responsible for maintenance. In any case the body responsible for maintenance must ensure that the components for maintenance related replacements are suitable for their applications, are used within their area of use, and enable interoperability to be achieved within the rail system while at the same time meeting the essential requirements. Such components must be traceable and certified in accordance with any national or international rule, or any code of practice widely acknowledged in the railway domain.
         7.   IMPLEMENTATION
         7.1.   General
         
         The Member State shall specify for TEN lines those parts of the energy subsystem, which are required for interoperable services (e.g. overhead contact line over tracks, sidings, stations, marshalling yards) and therefore need to comply with this TSI. In specifying these elements the Member State shall consider the coherence of the system as a whole.
         7.2.   Progressive strategy towards interoperability
         
         7.2.1.   Introduction
         
         The strategy described in this TSI applies to new, upgraded and renewed lines.
         Modification of existing lines to bring them into conformity with the TSIs may entail high investment costs and, consequently, can be progressive.
         In accordance with the conditions laid down in Article 20(1) of the Directive 2008/57/EC, the migration strategy indicates the way existing installations shall be adapted when it is economically justified to do so.
         7.2.2.   Migration strategy for voltage and frequency
         
         The choice of power supply system is a Member State decision. The decision should be taken on economic grounds, taking into account at least the following factors:
         
                     —
                  
                  
                     the existing power supply system in that Member State,
                  
               
                     —
                  
                  
                     any connection to railway line in neighbouring countries with an existing electrical power supply.
                  
               7.2.3.   Migration strategy for pantographs and OCL geometry
         
         The overhead contact line shall be designed for use by at least one of the pantographs with the head geometry (1 600 mm or 1 950 mm) specified in the CR LOC&PAS TSI clause 4.2.8.2.9.2.
         7.3.   Application of this TSI to new lines
         
         Chapters 4 to 6 and any specific provisions in paragraph 7.5 below apply in full to the lines coming within the geographical scope of this TSI (cf. paragraph 1.2) which will be put into service after this TSI enters into force
         7.4.   Application of this TSI to existing lines
         
         7.4.1.   Introduction
         
         Whilst the TSI can be fully applied to new installations, implementation on existing lines may require modifications of existing equipment. The degree of necessary modification will depend on the extent of conformity of the existing equipment. The following principles apply in the case of the CR TSI, without prejudice to clause 7.5 (Specific cases).
         Where Article 20(2) of the Directive 2008/57/EC applies meaning that an authorisation of placing into service is required, the Member State decides which requirements of the TSI must be applied taking into account the migration strategy.
         Where Article 20(2) of the Directive 2008/57/EC does not apply because a new authorisation of placing into service is not required, the conformity with this TSI is recommended. Where it is not possible to achieve conformity, the contracting entity informs the Member State of the reason thereof.
         When the Member State requires placing new equipment into service, the Contracting Entity shall define the practical measures and different phases of the project which are necessary to achieve the required levels of performance. These project phases may include transition periods for placing equipment into service with reduced levels of performance.
         An existing subsystem may allow the circulation of TSI-conform vehicles whilst meeting the essential requirements of Directive 2008/57/EC. The infrastructure manager should be able in this case, on a voluntary basis, to complete the Register of Infrastructure set out in Article 35 of Directive 2008/57/EC. The procedure to be used for the demonstration of the level of compliance with the basic parameters of the TSI shall be defined in the specification of the Infrastructure Register to be adopted by the Commission in accordance with that Article.
         7.4.2.   Upgrading/renewal of the OCL and/or the power supply
         
         It is possible to gradually modify all or part of the Overhead Contact Line and/or the power supply system — element by element — over an extended period of time to achieve conformance with this TSI.
         However the conformity of the entire subsystem can only be declared when all elements have been brought into conformity with the TSI.
         The process of upgrading/renewal should take into consideration the need of maintaining compatibility with the existing energy subsystem and other subsystems. For a project including elements not being TSI conform, the procedures for the assessment of conformity and EC verification to be applied should be agreed with the Member State.
         7.4.3.   Parameters related to maintenance
         
         While maintaining the energy subsystem, formal verifications and authorisations for placing into service are not required. However, maintenance replacements may be as far as reasonably practicable, be undertaken in accordance with the requirements of this TSI contributing to the development of interoperability.
         7.4.4.   Existing subsystem that are not subject to a renewal or upgrading project
         
         A subsystem in current operation may permit trains conforming to the requirements of the HS and CR rolling stock TSIs to operate whilst meeting the essential requirements. The Infrastructure Manager may in this case, on a voluntary basis, complete the Register of infrastructure in accordance with Annex C to this TSI to show the level of compliance with the basic parameters of this TSI.

            DETERMINATION OF THE MECHANICAL KINEMATIC PANTOGRAPH GAUGE
         
         E.1.   General
         
         E.1.1.   Space to be cleared for electrified lines
         
         In the case of lines electrified by an overhead contact line, an additional space should be cleared:
         
                     —
                  
                  
                     to accommodate the OCL equipment,
                  
               
                     —
                  
                  
                     to allow the free passage of the pantograph.
                  
               This annex deals with the free passage of the pantograph (pantograph gauge). The electrical clearance is considered by the Infrastructure Manager.
         E.1.2.   Particularities
         
         The pantograph gauge differs in some aspects from the obstacle gauge:
         
                     —
                  
                  
                     the pantograph is (partly) live and, for this reason, an electrical clearance is to be complied with, according to the nature of the obstacle (insulated or not),
                  
               
                     —
                  
                  
                     the presence of insulating horns should be taken into account, where necessary. Therefore a double reference contour has to be defined to take account of the mechanical and electrical interference simultaneously,
                  
               
                     —
                  
                  
                     in collecting condition, the pantograph is in permanent contact with the contact wire and, for this reason, its height is variable. So is the height of the pantograph gauge.

         The pantograph gauge is only met if the mechanical and electrical gauges are complied with simultaneously:

                     non-insulated obstacles (earthed or at a potential different from the OCL) shall remain outside the mechanical and electrical gauges.

         E.2.   Determination of the mechanical kinematic pantograph gauge
         
         E.2.1.   Determination of the width of the mechanical gauge
         
         E.2.1.1.   Scope
         
         The width of the pantograph gauge is mainly determined by the length and displacements of the pantograph under consideration. Beyond specific phenomena, phenomena similar to those of the obstacle gauge are found in the transverse displacements.
         The pantograph gauge shall be considered at the following heights:
         
                     —
                  
                  
                     the upper verification height h’o
                        ,
                  
               
                     —
                  
                  
                     the lower verification height h’u
                        .
                  
               Between those two heights, it can be considered that gauge width varies in a linear way.
         The various parameters are shown in figure E.2.
         E.2.1.2.   Calculation methodology
         
         The pantograph gauge width shall be determined by the sum of the parameters defined below. In the case of a line run by various pantographs, the maximum width should be considered.
         For the lower verification point with h = h'u:
            
         
         
            
         For the upper verification point with h = h'o
            :
         
            
         NOTE i/a = inside/outside curve.
         For any intermediate height h, width is determined by means of an interpolation:
         
            
         E.2.1.3.   Half-length bw
                of the pantograph bow
         
         The half-length bw of the pantograph bow depends of the type of pantograph used. The pantograph profile(s) to be considered are defined in CR LOC&PAS TSI clause 4.2.8.2.9.2.
         E.2.1.4.   Pantograph sway ep
               
            
         
         The sway mainly depends on the following phenomena:
         
                     —
                  
                  
                     play q + w in the axle boxes and between bogie and body,
                  
               
                     —
                  
                  
                     the amount of body inclination taken into account by the vehicle (depending on the specific flexibility s'0
                        , the reference cant D’0
                         and the reference cant deficiency I’0
                        ),
                  
               
                     —
                  
                  
                     the mounting tolerance θ of the pantograph on the roof,
                  
               
                     —
                  
                  
                     the transverse flexibility τ of the mounting device on the roof,
                  
               
                     —
                  
                  
                     the height under consideration h’.

         E.2.1.5.   Additional overthrows
         
         The pantograph gauge has a specific additional overthrows. In case of standard track gauge the following formula applies:
         
            
         For other track gauges the national rules apply.
         E.2.1.6.   Quasi-static effect
         
         Since the pantograph is installed on the roof, the quasi-static effect plays an important role in the calculation of the pantograph gauge. That effect is calculated from the specific flexibility s0’, reference cant D’0
             and reference cant deficiency I’0
            :
         
            
         
            
         NOTE: Pantographs are normally mounted on the roof of a power unit, whose reference flexibility s0’ is generally smaller than that of the obstacle gauge s0.
         E.2.1.7.   Allowances
         
         According to gauge definition, the following phenomena should be considered:
         
                     —
                  
                  
                     loading dissymmetry,
                  
               
                     —
                  
                  
                     the transverse displacement of the track between two successive maintenance actions,
                  
               
                     —
                  
                  
                     the cant variation occurring between two successive maintenance actions,
                  
               
                     —
                  
                  
                     oscillations generated by track unevenness.
                  
               The sum of the abovementioned allowances is covered by Σj.
         E.2.2.   Determination of the height of the mechanical gauge
         
         Gauge height shall be determined on the basis of the static height hcc
            , of the contact wire at the local point under consideration. The following parameters should be considered:
         
                     —
                  
                  
                     the raising fs
                         of the contact wire generated by the pantograph contact force. The value of fs
                         depends on the OCL type and so shall be determined by the Infrastructure Manager in accordance with clause 4.2.16,
                  
               
                     —
                  
                  
                     the raising of the pantograph head due to the pantograph head skew generated by the staggered contact point and the wear of the collector strip fws
                         + fwa
                        . The permissible value of fws
                         is shown in CR LOC&PAS TSI and fwa
                        . depends on maintenance requirements.
                  
               The height of the mechanical gauge is given by the following formula:
         
            
         E.3.   Reference parameters
         
         Parameters for the kinematic mechanical pantograph gauge and for determination of the maximum lateral deviation of the contact wire shall be as follows:

               E.4.   Calculation of maximum lateral deviation of contact wire
         
         The maximum lateral deviation of the contact wire shall be calculated by taking into consideration the total movement of the pantograph with respect to the nominal track position and the conducting range (or working length, for pantographs without horns made from a conducting material) as follows:

             – defined in clause 4.2.8.2.9.1 and 4.2.8.2.9.2 of CR LOC&PAS TSI.
      
      
         ANNEX F
         
            PHASE AND SYSTEM SEPARATION SECTION SOLUTIONS
         
         Phase separation section designs are described in EN50367:2006, Annex A.1.3 (long neutral section) and in Annex A.1.5 (split neutral section - the overlaps can be replaced by double section insulators) or described in the Figures F.1 or F.2.

            Separation section with neutral section insulators
         
         
            
         In the case of Figure F.1, the neutral sections (d) may be formed by neutral section insulators and the dimensions shall be as follows:
         D ≤ 8 m
         This small length ensures that the probability of a train stopping inside the phase separation does not require the adequate means to restart.
         The length of d shall be chosen in accordance with the system voltage, maximum line speed and the maximum pantograph width.

         The span covering three consecutive pantographs shall be greater than 80 m (L′′). The intermediate pantograph may be arranged at any position within this span. Depending on the minimum spacing between two adjacent operating pantographs the infrastructure manager shall state the maximum operating train speed. No electrical connection may exist between pantographs in service.

            POWER FACTOR
         
         This Annex deals only with inductive power factor and power consumption over the range of voltage from U
            min1 to U
            max1 defined in EN 50163.
         Table G.1 gives the total inductive power factor λ of a train. For the calculation of λ, only the fundamental of the voltage at pantograph is taken into account.

                     For yards or depot, the power factor of the fundamental wave shall be ≥ 0,8 (NOTE 1) under the following conditions: the train is hotelling with traction power switched off and all auxiliaries running and the active power being drawn is greater than 200 kW.
                     The calculation of overall average λ for a train journey, including the stops, is taken from the active energy WP (MWh) and reactive energy WQ (MVArh) given by a computer simulation of a train journey or metered on an actual train.

                                 In order to control the total power factor of the auxiliary load of a train during the coasting phases, the overall average λ (traction and auxiliaries) defined by simulation and/or measurement shall be higher than 0,85 over a complete timetable journey. (typical journey between two stations including commercial stops).

               During regeneration, inductive power factor is allowed to decrease freely in order to keep voltage within limits.
         NOTE 1: Higher power factors than 0,8 will result in better economic performance due to a reduced requirement for fixed equipment provision.
         NOTE 2: on line categories III to VII, for rolling stock existing before publication of this TSI, the Infrastructure Manager may impose conditions e.g. economic, operating, power limitation for acceptance of interoperable trains having power factors below the value specified in Table G.1.
