7 1.0. The energy subsystem as part of the conventional rail system The conventional rail system has been broken down into subsystems as defined in Annex II to Directive 2001/16/EC, as amended by Directives 2004/50/EC and 2007/32/EC. The following subsystems are defined, two of which are operational: a. infrastructure; b. energy; c. control and command and signalling; d. traffic operation and management; e. rolling stock; f. maintenance (operational); g. telematic applications for passenger and freight services (operational). There are two TSIs describing specific aspects of the railway system and relating to several subsystems: h. safety of railway tunnels; i. accessibility to people with reduced mobility. The rolling stock subsystem is described within the following TSIs: j. freight wagons; k. locomotives and traction unit; l. passenger carriages m. noise; Aspects of maintenance will be integrated into the structural TSIs, so that no separate operational TSI for maintenance will exist. 7 of 100

8 1.1. Technical scope This TSI concerns the energy subsystem of the trans-european conventional rail system. It is included in the structural area of the list of Annex II to Directive 2001/16/EC, as amended by Directives 2004/50/EC and 2007/32/EC. According to Annex I of the Directive, the conventional rail network comprises the following categories: a. lines intended for passenger services; b. lines intended for mixed traffic (passenger and freight); c. lines specially designed or upgraded for freight services; d. passenger hubs; e. freight hubs, including intermodal terminals; f. lines connecting the abovementioned elements. In order to deliver interoperability cost-effectively further subcategories of all categories of lines mentioned will, where necessary, be developed. The functional and technical specifications of the present TSI may vary according to the subcategory. The categories of line for the conventional rail system are specified in the Infrastructure CR TSI Geographical scope The geographical scope of this TSI is the trans-european conventional rail system as described in Annex I to Directive 2001/16/EC as amended by Directives 2004/50/EC and 2007/32/EC. Reference should be made, in particular, to the lines of the conventional rail network referred to in Decision No 1692/96/EC 1 of the European Parliament and of the Council of 23 July 1996 on Community guidelines for the development of the trans-european transport network, or those included in any update of this Decision resulting from the revision provided for in Article 21 of the Decision Content of this TSI In accordance with Article 5(3) of Directive 2001/16/EC, as amended by Directives 2004/50/EC and 2007/32/EC, this TSI: a. indicates its intended scope and description of the sub-system Chapter 2; b. lays down essential requirements for Energy subsystem Chapter 3; c. establishes the functional and technical specifications to be met by the subsystem and its interfaces vis-à-vis other subsystems Chapter 4; d. determines the interoperability constituents and interfaces covered by European specifications, including European standards, which are necessary to achieve interoperability within the trans-european conventional rail system Chapter 5; e. states, in each case under consideration, the procedures for the assessment of conformity or suitability for use.

10 2. Scope and description of the subsystem 2.1. Scope The Energy TSI specifies those requirements which are necessary to assure the interoperability of the trans-european conventional 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 third rail and contact shoe system is not a target system, this TSI does not describe the characteristics or functionality of such a system. Transfer the current Supply current (Substation) Convey the current Figure 1: Energy subsystem Energy subsystem Rolling stock subsystem The Energy subsystem consists of: a. substations: connected on their 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, 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 part of the contact line system; e. return circuit: all conductors which form the intended path of 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; 10 of 100

11 f. current collectors (pantographs) transmit electrical energy from the overhead contact line system to the train on which they are installed. The pantograph is integrated into and put into service with the train, and is in the scope of the conventional Locomotives and Traction Units (LOC) CR TSI. The interaction between pantograph and the overhead contact line is specified in the Energy CR TSI Description of the subsystem 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 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 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 Overhead contact line and pantograph The compatible geometry of the overhead contact line and 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 LOC CR 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. 11 of 100

12 2.3. Interfaces with other subsystems and within the subsystem Introduction The energy subsystem interfaces with some of the other subsystems of the trans-european conventional rail system in order to achieve the envisaged performance 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 conventional 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 Interfaces concerning overhead line equipment and pantographs and their interaction a. On conventional lines, the contact wire gradient & 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 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. 12 of 100

20 4. Characterisation of the subsystem 4.1. Introduction The trans-european conventional rail system, to which Directive 2001/16/EC as amended by Directives 2004/50/EC and 2007/32/EC applies and of which the subsystem is a part, is an integrated system whose consistency must 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 trans-european conventional 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 and 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 Infrastructure Register is in Annex D to this TSI. For Specific Cases, see chapter 7.3; where reference is made to EN standards, any variations called "national deviations" or "special national conditions" in the EN do not apply Functional and technical specifications of the subsystem General provisions The performance to be achieved by the Energy subsystem shall correspond to the relevant performance as specified for each category of line (defined in the Infrastructure CR TSI) of the trans-european conventional rail system, with respect to: o the maximum line speed, type of train, and o the power demand of the trains at the pantographs Basic parameters characterizing the energy subsystem The basic parameters characterising the energy subsystem are: Power supply o Voltage and frequency (4.2.3) o Parameters relating to supply system performance (4.2.4) o Continuity of power supply in case of disturbances (4.2.5) o Current capacity, DC systems, trains at standstill (4.2.6) o Regenerative braking (4.2.7) o Electrical Protection Coordination Arrangements (4.2.8) o Harmonics and Dynamic Effects (4.2.9) Geometry of the OCL and quality of current collection o Geometry of the overhead contact line (4.2.13) o Free passage gauge of pantographs (4.2.14) o Mean Contact Force (4.2.15) 20 of 100

21 o Dynamic behaviour and quality of current collection (4.2.16) o Pantograph spacing used for the design of the overhead contact line (4.2.17) o Contact wire material (4.2.18) o Phase separation sections (4.2.19) o System separation sections (4.2.20) Voltage and frequency Locomotives and traction units need standardisation of voltage and frequency. The values and limits of the voltage and frequency at the terminals of the substation and at the pantograph shall comply with EN 50163:2004, clause 4. The 25 kv 50 Hz system is to be the target supply system, for reasons of compatibility with the electrical generation and distribution systems and standardisation of substation equipment. However, due to the high costs needed to migrate from other system voltages to the 25 kv system and the possibility of using multi-system traction units, the use of the following systems for new, upgraded or renewed subsystems is permitted: o AC 15 kv 16.7 Hz o DC 3 kv, 1.5 kv Nominal voltage and frequency shall be listed in the Infrastructure Register (see Annex D). Conformity shall be demonstrated by means of a design review 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: o the maximum train current, o the power factor of trains, o the mean useful voltage, o limits of the voltage at the pantograph. The Infrastructure Manager shall declare the maximum train current in the Infrastructure Register (see Annex D). The railway undertaking shall ensure this value is not exceeded. The Energy subsystem design shall assure 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. The power factor of trains shall be in accordance with requirements in Annex I. The calculated mean useful voltage at the pantograph shall comply with EN 50388:2005, clauses 8.3 and 8.4, using the design data for the power factor according to Annex I in EN 50388:2005 clause 6.2 with the exception of hotelling trains in yards and sidings for which the specification is given in LOC CR RST. The conformity assessment shall be carried out in accordance with EN 50388:2005, clauses , (simulation only) and To stabilise the power supply under all operating conditions EN50388 clause 7.2 shall be fulfilled. The conformity assessment is carried out in RST CR TSI. 21 of 100

22 Continuity of power supply in case of disturbances The power supply and the overhead contact line system shall be designed to enable continuity of operation in case of disturbances. This shall be achieved by sectioning overhead contact line system into supply sections and by the provision of redundant equipment in substations. Conformity assessment shall be carried out by checking the circuit diagrams. It shall be demonstrated that the provisions for continuity, as designed, have been installed Current capacity, DC systems, trains at standstill The overhead contact line of DC systems shall be designed to sustain 300A (for a 1.5kV supply system) and 200A (for a 3kV 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 Infrastructure Register (see Annex D). The OCL shall be designed taking into account the temperature limits in accordance with Annex F. Conformity assessment shall be carried out in accordance with EN 50367:2006, Annex A 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. The substation control and protection devices in the power supply system shall allow the use of regenerative braking unless the conditions described in EN50388:2005 clause occur. Conformity assessment for AC power supply fixed installations shall be carried out according EN50388:2005, clause DC power supply systems shall be designed to permit the use of regenerative braking as a service brake at least by exchanging power with other trains fulfilling the requirements in EN50388:2005 clause Conformity assessment for DC power supply shall be carried out by a design review Electrical protection coordination arrangements Electrical protection coordination design of the Energy subsystem shall comply with the requirements detailed in EN 50388:2005, clause 11 ( 2 ). Conformity assessment shall be carried out for design and operation of substations in accordance with EN50388:2005 clause Regarding EN 50388:2005 clause 11 Table 8. Immediate tripping means that for high level current, substation or train circuit breaker should operate without introducing intentional delay. 22 of 100

23 Harmonics and dynamic effects The CR energy subsystem for AC supply, shall withstand overvoltages generated by rolling stock harmonics up to the limits stated in EN 50388:2005 clause Conformity assessment shall consist of a compatibility study that demonstrates that the subsystem element can withstand harmonics up to the defined limits according to EN50388:2005, clause 10. Conformity assessment shall be conducted according to EN50388:2005 clause 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 External electromagnetic compatibility External electromagnetic compatibility is not a specific characteristic of the trans-european conventional rail network. Energy supply installations shall comply with EN :2006 to meet all requirements concerning electromagnetic compatibility. No conformity assessment is required within this TSI 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 Geometry of the overhead contact line Overhead contact line shall be designed for use by pantographs with the head geometry specified in the Locomotive and Traction Unit CR TSI. 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 trans-european rail network. The nominal contact wire height, the maximum lateral deviation under cross-wind and the maximum wind speed at which unrestricted operation is permitted, shall be listed in the Infrastructure Register (see Annex D) Contact wire height The nominal contact wire height shall be in the range of m. 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 EN50119:2001 clause The maximum design contact wire height shall be 6.2m (see Annex J). 23 of 100

24 Conformity assessment shall be carried out by design review Variation in contact wire height The variation in contact wire height shall fulfil the requirements imposed by EN50119:2001 clause It is permissible for t The contact wire gradient specified in EN50119:2001 clause 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 , only the requirement related to the maximum contact force shall be complied with. Conformity assessment shall be carried out by design review and measurements before putting into service 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 Table Maximum lateral deviation Pantograph length Maximum lateral deviation 1600mm 0,4m 1950mm 0,55m For different contact wire height and curve track the values shall be adjusted taking into account the movement of the pantograph and track tolerances in Annex G.

25 Free passage gauge of pantographs No part of the energy sub-system shall enter the kinematic mechanical pantograph gauge (see Annex G figure G.1) except for the contact wire and registration arm. The mechanical kinematic pantograph gauge for interoperable lines is determined using the method shown in Annex G clause G.2 and the pantograph profiles defined in CR LOC TSI. The pantograph profiles that can operate on the route will be recorded in the Infrastructure Register the (see Annex D). This gauge shall be calculated using a kinematic method, with values for the pantograph sway at the upper verification point - e pu of m at a height 5,0m and for the pantograph sway at the lower verification point - e po of m at a height 6,5m, in accordance with Annex G clause G and other values in accordance with Annex G clause G.3 and electrical clearance in accordance with EN 50119:2001 clause Assessment shall be by design review Mean contact force The mean contact force F m is the statistical mean value of the contact force. F m is formed by the static and aerodynamic components of the pantograph contact force. The static contact force is defined in EN50367:2006 clause 7.1. The ranges of F m for each of the power supply systems are defined in table Table Ranges of the mean contact force Supply system F m up to 200km/h AC 60N < F m < 0,00047*v² + 90 DC 3kV 70N < F m < 0,00097*v² DC 1,5kV 70N < F m < 0,00097*v² where [F m ] = mean contact force in N and [v] = speed in km/h. In accordance to clause , overhead contact lines shall be designed to be capable to sustain this upper limit force curve given in the table Conformity assessment shall be carried out in accordance with EN 50317:2002, clause Dynamic behaviour and quality of current collection Requirements The overhead contact line shall be designed in accordance with the requirements for dynamic behaviour. Contact wire uplift at the design line speed shall comply with the stipulations in Table of 100

26 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 in accordance with EN 50367:2006, clause 7.2 by assessment of: o Contact wire uplift and either o Mean contact force Fm and standard deviation σ max or o Percentage of arcing The Contracting Entity shall declare the method to be used for verification. The values to be achieved by the chosen method are set out in Table Table Requirements for dynamic behaviour and current collection quality Requirement For v> 160km/h For v 160km/h Space for steady arm uplift 2S 0 Mean contact force F m See clause Standard deviation at maximum line speed σ max (N) 0.3 F m Percentage of arcing at maximum line speed, NQ (%) (minimum duration of arc 5ms) 0.1 for AC systems 0.2 for DC systems 0.1 For definitions, values and test methods refer to EN50317:2002 and EN50318:2002. S 0 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 F m 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 1,5S 0 (refer to EN50119:2001 clause ). Maximum force (F max ) on an open route is usually within the range of F m plus three standard deviations σ max ; higher values may occur at particular locations and are given in EN50119:2001, table 1 clause For rigid components such as section insulators in overhead contact line systems, the contact force can increase up to a maximum of 350 N Conformity assessment Assessment principles When assessing the dynamic behaviour and the quality of the current collection using simulation programs according to EN50318:2002 or measurements according to EN50317:2002, the presentation of results shall be appropriate to the speed of the line. For the purposes of simulation and analysis of the results, representative features (for example tunnels, crossovers, neutral sections etc.) shall be used. 26 of 100

27 Interoperability Constituent Overhead Contact Line 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. The simulations shall be made using at least two different TSI compliant 3 pantographs for the appropriate system, up to the design speed of the pantograph and the proposed Interoperability Constituent Overhead Contact Line for both a single pantograph and multiple pantographs with spacing according table In order to be acceptable, the simulated current collection quality shall be within the limits of table for uplift, mean contact force and standard deviation for each of the pantographs. If the simulation results are acceptable, a site test with a representative section of the new overhead contact line shall be undertaken using one of the pantographs used in the simulation, installed on a train or locomotive producing a mean contact force at the envisaged design speed as required by clause when operated on one of the overhead contact line systems. In order to be acceptable, the measured current collection quality shall be within the limits of table 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 match the requirements of the line. This aspect is covered by this TSI Interoperability Constituent Pantograph In addition to the pantograph requirements in the LOC CR TSI, a new design of a pantograph shall be assessed by simulation according to EN50318:2002. The simulations shall be made using at least two different TSI compliant 4 overhead contact lines for the appropriate system, at the design speed of the pantograph. The simulated current collection quality shall be within the limits of table for uplift, mean contact force and standard deviation for each of the overhead contact lines. If the simulation results are acceptable, a site test shall be made using a representative section of one of the overhead contact lines used in the simulation; the interaction characteristics shall be measured in accordance with EN50317:2002. The pantograph shall be mounted on a train or locomotive so as to produce a mean contact force within the upper and lower limits as required by clause for the design speed of the pantograph. The measured current collection quality shall be within the limits of table for uplift, mean contact force and standard deviation. If all the assessments are passed successfully, the tested pantograph design shall be considered as compliant. For the use on various designs of rolling stock see clause This aspect is covered by the LOC CR TSI IC OCL in a newly installed line (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 installed on rolling stock exhibiting the mean contact force characteristics as required by clause of this TSI for the envisaged design speed. 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 of table This aspect is covered by this TSI. 3 i.e. a pantograph certificated as an Interoperability Constituent 4 i.e. an Overhead Contact Line certificated as an Interoperability Constituent 27 of 100
