1. INTRODUCTION

1.1. Technical scope

This TSI concerns the Energy subsystem of the trans-European high-speed rail system. The energy subsystem is one of the subsystems listed in Annex II(1) to Directive 96/48/EC as modified by Directive 2004/50/EC.

According to Annex I of the Directive, high-speed lines comprise:

— specially built high-speed lines equipped for speeds generally equal to or greater than 250 km/h,

— specially upgraded high-speed lines equipped for speeds of the order of 200 km/h,

— specially upgraded high-speed lines or lines specially built for high speed, which have special features as a result of topographical or environmental, relief or town-planning constraints, on which speed must be adapted individually

In this TSI, these lines have been classified as category I, category II and category III respectively.

1.2. Geographical scope

The geographical scope of this TSI is the trans-European high-speed rail system as described in Annex I to Directive 96/48/EC as modified by Directive 2004/50/EC.

Reference shall be made in particular to the lines of the trans-European rail network described in Decision No 1692/96/EC of the European Parliament and of the Council of 23 July 1996 as modified by Decision No 884/2004/EC on Community guidelines for the development of the trans-European transport network or in any subsequent update to the same Decision as a result of the revision provided for in Article 21 of that Decision.

1.3. Content of this TSI

In accordance with Article 5(3) of Directive 96/48/EC as modified by Directive 2004/50/EC, this TSI:

(a) indicates its intended scope (chapter 2);

(b) lays down essential requirements for the Energy subsystem (chapter 3) and its interfaces vis-à-vis other subsystems (chapter 4);

(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 which shall be covered by European specifications, including European standards, which are necessary to achieve interoperability within the trans-European high speed rail system (chapter 5);

(e) states, in each case under consideration, which procedures are to be used in order to assess the conformity or the suitability for use of the interoperability constituents, or the EC verification of the subsystems (chapter 6);

(f) indicates the strategy for implementing this TSI (chapter 7);

(g) indicates for the staff concerned, the professional competencies and health and safety conditions at work required for the operation and maintenance of the subsystem, as well as for the implementation of the TSI (chapter 4).

In accordance with Article 6(3) of the Directive, provision may be made for specific cases for each TSI; these are indicated in chapter 7.

This TSI also sets out, in chapter 4, the operating and maintenance rules specific to the scope indicated in paragraphs 1.1 and 1.2 above.

2. SUBSYSTEM DEFINITION/SCOPE

2.1. Scope

The Energy TSI specifies those requirements which are necessary to assure the interoperability of the trans-European high-speed rail system. This TSI covers the trackside part of the Energy subsystem and the part of the Maintenance subsystem that relates to the trackside part of the Energy subsystem. The Energy subsystem of the trans-European high-speed rail system comprises all fixed installations that are required to supply, with respect to the essential requirements, the trains from high-voltage single-phase or three-phase networks.

The energy subsystem also includes the definition and quality criteria for interaction between pantograph and overhead contact line.

The Energy subsystem consists of:

— 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 overhead contact line system;

— sectioning points: electrical equipment located at intermediate locations between substations to supply and parallel overhead contact lines and to provide protection, isolation, auxiliary supplies;

— overhead 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 pantographs. The overhead contact line system is also equipped with manually or remotely controlled disconnectors which are required to isolate sections or groups of the overhead contact line system according to operational necessity. Feeder lines are part of the overhead contact line system;

— return circuit: all conductors which form the intended path of the traction return current and the current 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;

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 High Speed Rolling Stock TSI. The interaction between pantograph and the overhead contact line is specified in this TSI.

2.2. Definition of the subsystem

2.2.1. Electrification system

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.

High-speed trains need a correspondingly high power. In order to supply the trains with minimum resistive losses, it is necessary to have a high supply voltage and (correspondingly) a lower current. The power supply system has to be designed such that every train will be supplied with the necessary power. Therefore, the power consumption of each train and the operating schedule are important aspects for performance.

Modern trains are often capable of using regenerative braking to return energy to the power supply, reducing power consumption overall. Therefore, the power supply system has to be designed to accept regenerative braking energy.

In any electrical system, short-circuits and other fault conditions occur. The electrification system needs to be designed so that the subsystem 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 electrification system has to be able to restore supply to all installations as soon as possible to resume operations.

2.2.2. Geometry of 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 lateral deviation in still air and 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.

2.2.3. Interaction of overhead contact line and pantograph

At the high speeds envisaged for the trans-European high-speed rail system, the interaction of overhead contact line and 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:

— static and aerodynamic effects dependant 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,

— the compatibility of the contact strip material with the contact wire,

— the dynamic characteristics of the overhead contact line and pantograph(s),

— the protection of the pantograph(s) and overhead contact line in the case of a broken pantograph contact strip,

— 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.

2.2.4. Transition between high-speed lines and other lines

Along a line of route, different requirements will apply. The transition between sections having different requirements affects the power supply and overhead contact line system and is, therefore, an aspect to be dealt with in the Energy TSI.

2.3. Links with other subsystems and within the subsystem

2.3.1. Introduction

The Energy subsystem has links with other subsystems of the trans-European high-speed rail system in order to achieve the envisaged performance. These links are covered by the definition of interfaces and performance criteria.

2.3.2. Links concerning electrification system

— Voltage and frequency and their permissible ranges interface with the High Speed Rolling Stock subsystem.

— The power installed on the lines and the specified power factor determines the performance of the high-speed rail system and interfaces with the High Speed Rolling Stock subsystem.

— Regenerative braking reduces energy consumption and interfaces with the High Speed Rolling Stock subsystem.

— 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 High Speed Rolling Stock subsystem.

— Electrical interference and harmonic emissions interface with the High Speed Rolling Stock and Control-Command and Signalling subsystems.

2.3.3. Links concerning overhead line equipment and pantographs

— On high-speed lines, the contact wire height needs special attention in order to avoid excessive wear. The contact wire height interfaces with the Infrastructure and High Speed Rolling Stock subsystems.

— Vehicle and pantograph sway interfaces with the Infrastructure subsystem.

2.3.4. Links concerning interaction of overhead contact line and pantograph

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 Energy subsystem.

2.3.5. Links concerning phase and system separation sections

— To pass transitions of electrification systems and phase separation sections, without bridging, the number and arrangement of pantographs on trains shall be stipulated. This interfaces with the High Speed Rolling Stock subsystem

— To pass transitions of electrification systems and phase separation sections, without bridging, control of train current is required. This interfaces with the Control-Command and Signalling subsystem.

— When passing through 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 trans-European high-speed rail system, to which Directive 96/48/EC as modified by Directive 2004/50/EC applies and of which the Energy subsystem is a part, is an integrated system whose compatibility shall be verified. This compatibility shall 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 sections 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 high speed 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 sections 6.1.2.3 and 6.2.2.2.

Taking account of all the applicable essential requirements, the Energy subsystem is characterised by the specifications set out in clauses 4.2 to 4.8.

For Specific Cases, see chapter 7.4; where reference is made to EN standards, any variations called ‘national deviations’ or ‘special national conditions’ in the EN do not apply. For EN clauses incorporating tables, column headings HS, UP, and Conn shall be taken to mean categories I, II and III respectively.

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 as specified for each category of line of the trans-European high-speed rail system, with respect to:

— the maximum line speed, and

— the power demand of the trains at the pantographs.

The Energy subsystem design shall assure the specified performance.

The Infrastructure Manager shall define, on a short section of route, connecting a high-speed line with another line, the position where the requirements of the Energy subsystem TSI for high-speed lines start to apply.

4.2.2. Voltage and frequency

Traction units need standardisation of the voltage and frequency values. Table 4.2.2 lists the nominal voltages and nominal frequencies of the electric power supply systems that shall be used depending upon the line category.

Nominal voltages and frequencies Category I Category II Category III AC 25 kV 50 Hz X X X AC 15 kV 16,7 Hz (1) X X DC 3 kV (2) X X DC 1,5 kV — X X (1) In Member States with networks electrified at AC 15 kV 16,7 Hz, it is permissible for this system to be used for new category I lines. It is permissible for the same system to be applied in adjacent countries when it can be economically justified by the Member State. No assessment is required in this case. (2) It is permissible for the DC 3 kV supply to be used in Italy, Spain and Poland for existing and new category I line sections operated at 250 km/h when electrification with AC 25 kV 50 Hz could create a risk of disturbing ground and on-board signalling equipment on an existing line.

The voltage and frequency at the terminals of the substation and at the pantograph shall comply with EN 50163:2004, clause 4. Nominal voltage and frequency shall be listed in the Infrastructure Register. Annex D to this TSI lists the parameters of the Infrastructure Register relevant for the Energy subsystem. Conformity shall be demonstrated by means of a design review.

4.2.3. System performance and installed power

The Energy subsystem shall be designed to meet the required performance in respect of:

— the line speed,

— the minimum possible headway,

— the maximum train current,

— the power factor of trains,

— the timetable and planned services,

— the mean useful voltage,

according to the appropriate line category.

The Infrastructure Manager shall declare the line speed, and the maximum train current in the Infrastructure Register (see Annex D). The Energy subsystem design shall assure the ability of the power supply to achieve the specified performance.

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 in EN 50388:2005 clause 6 with the exception of hotelling trains in yards and sidings for which the specification is given in HS TSI RST (2006), clause 4.2.8.3.3. The conformity assessment shall be carried out in accordance with EN 50388:2005, clauses 14.4.1, 14.4.2 (simulation only) and 14.4.3.

4.2.4. 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 regenerative braking.

DC power supply systems are not required to be designed to permit the use of regenerative braking as a service brake. However, where it is permissible to do so, it shall be recorded in the Infrastructure Register.

The fixed installations and their protection devices shall permit the use of regenerative braking unless the conditions described in EN50388:2005 clause 12.1.1 occur. Conformity assessment for fixed installations shall be carried out according EN 50388:2005, clause 14.7.2.

4.2.5. 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.

4.2.6. External electromagnetic compatibility

External electromagnetic compatibility is not a specific characteristic of the trans-European high-speed rail network. Energy supply installations shall comply with EN 50121-2:1997 to meet all requirements concerning electromagnetic compatibility.

No conformity assessment is required within this TSI.

4.2.7. 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 the installation 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.

4.2.8. 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.

4.2.9.1. Overall design

The design of the overhead contact line shall comply with EN 50119:2001, clauses 5.1, 5.2.1.2, 5.2.4.1 to 5.2.4.8, 5.2.5, 5.2.6, 5.2.7, 5.2.8.2, 5.2.10, 5.2.11 and 5.2.12. The design and operation of overhead contact lines presumes that pantographs are equipped with an automatic dropping device (ADD) (see High Speed Rolling Stock TSI clauses 4.2.8.3.6.4 and 4.2.8.3.8.4).

Additional requirements, concerning high-speed lines are specified hereafter.

4.2.9.2. Geometry of overhead contact line

Overhead contact line shall be designed for use by pantographs with the head geometry specified in clause 4.2.8.3.7.2 of the High Speed Rolling Stock TSI, and trains as specified in the High Speed Rolling Stock TSIs.

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 compatibility of the trans-European rail network. The permissible data for overhead contact line geometry is given in Table 4.2.9.

Table 4.2.9

Permissible data for overhead contact line geometry

Description Category I Category II Category III Nominal contact wire height (mm) Between 5 080 and 5 300 Between 5 000 and 5 500 AC — between 5 000 and 5 750 DC — between 5 000 and 5 600 Minimum contact wire height (mm) — AC — 4 950 DC — 4 900 Maximum Contact Wire Height (mm) — AC — 6 000 DC — 6 200 Contact wire gradient No planned gradients EN50119:2001 clause 5.2.8.2 Permissible lateral deviation of the contact wire in relation to the track centre line under action of a cross wind The smaller value of either 0,4 m or (1,4 – L 2) m

The permissible contact wire deviation under the action of a cross wind shall be calculated for contact wire heights above 5 300 mm and/or on curved track. It shall be calculated using the half-width of the dynamic envelope of the European pantograph passage, L 2. L 2 shall be calculated in accordance with EN 50367:2006 Annex A.3.

The contact wire height and the wind speed at which unrestricted operation is possible shall be listed in the Infrastructure Register (see Annex D).

For lines referred to in Table 4.2.2 note (2), the nominal contact wire height shall be between 5 000 mm and 5 300 mm.

Lines of category II and III:

The nominal contact wire height may be higher on lines with mixed freight and passenger traffic to permit the operation of trailers with oversize gauge, but the maximum wire height stated in table 4.2.9 shall not be exceeded. The requirements for the quality of current collection shall be maintained (see 4.2.16).

At level crossings (not permissible on Category I lines), the contact wire height shall be determined by national rules or in the absence of national rules, EN 50122-1:1997 clauses 4.1.2.3 and 5.1.2.3.

All Lines

Conformity assessment shall be carried out by design review and measurements before putting into service in accordance with EN 50119:2001, clause 8.5.1.

4.2.10. Compliance of the overhead contact line system with infrastructure gauge

The design of the overhead contact line system shall comply with the infrastructure gauges defined in clause 4.2.3 of the High Speed Infrastructure TSI. Overhead contact line design shall comply with the kinematic envelope of the vehicles. The gauge to be complied with shall be identified in Infrastructure Register (see Annex D).

The design of structures shall take into account the space necessary for the passage of pantographs in contact with the overhead line equipment and for installation of the overhead contact line itself. The dimensions of tunnels and other structures shall be mutually compatible with the geometry of overhead contact line and the kinematic envelope of the pantograph. High Speed Rolling Stock TSI clause 4.2.3.1 specifies the reference profile of the pantograph. The space necessary for installation of the overhead contact line shall be stipulated by the Infrastructure Manager.

Conformity assessment shall be carried out within the Energy subsystem by a design review.

4.2.11. Contact wire material

Permissible materials for contact wires are copper and copper-alloy. The contact wire shall comply with the requirements of EN 50149:2001 clauses 4.1 to 4.3 and 4.5 to 4.8.

Conformity assessment shall be carried out by design review and during production phase of the contact wire.

4.2.12. Contact wire wave propagation speed

The speed of wave propagation in contact wires is a characteristic parameter for assessing the suitability of overhead contact line for high-speed operation. This parameter depends upon the specific mass and the tensile stress in the contact wire. The wave propagation speed shall be adjusted so that the chosen line speed is no greater than 70 % of the wave propagation speed.

Conformity assessment shall be carried out by design review.

4.2.13. Not used

4.2.14. Static contact force

Static contact force is defined in EN 50206-1:1998 clause 3.3.5, and is exerted by the pantograph on the contact wire. The overhead contact line shall be designed for a static contact force as specified in Table 4.2.14.

Table 4.2.14

Static Contact Forces

Nominal Value (N) Range for application (N) AC 70 60 to 90 DC 3 kV 110 90 to 120 DC 1,5 kV 90 70 to 110

For DC 1,5 kV systems, the overhead contact line shall be designed to withstand a static contact force of 140 N per pantograph in order to avoid overheating of the contact wire with a train at standstill with its auxiliaries working.

Conformity assessment shall be carried out by design review and measurements in accordance with EN 50317:2002.

4.2.15. Mean contact force

The mean contact force Fm is formed by the static and aerodynamic components of the pantograph contact force with dynamic correction. Fm represents a target value to be achieved in order to ensure current collection quality without undue arcing and to limit wear and hazards to contact strips.

The mean contact force Fm applied by a pantograph on the contact wire is shown as a function of running speed in Figure 4.2.15.1 for AC lines, and figure 4.2.15.2 for DC lines. Overhead contact line shall be designed to be capable of sustaining this force curve for all pantographs on a train.

Maximum force (Fmax ) on an open route is usually within the range of Fm plus three standard deviations σ; higher values may occur elsewhere.

For speeds higher than 320 km/h, values for the mean contact force are not detailed in the TSI; additional specifications are needed, these specifications are an Open Point. In this case, National Rules shall apply.

Conformity assessment shall be carried out in accordance with EN 50317:2002, clause 6 for AC and DC systems at speeds above 80km/h.

Figure 4.2.15.1

Mean contact force Fm for AC systems as a function of speed

AC Curve C2 Fm = 0,001145 × v2 + 70 (N) AC Curve C Fm = 0,00097 × v2 + 70 (N) AC Curve C1 Fm = 0,000795 × v2 + 70 (N)

For new lines and when upgrading existing lines of all categories, the curve C shall be used.

New lines may additionally permit the use of Pantographs following C1 or C2 curves. Existing lines may require the use of pantographs following curves C1 or C2; the curve applied shall be stated in the Infrastructure Register.

Figure 4.2.15.2

Mean contact force Fm for DC systems as a function of speed

DC 3 kV Fm = 0,00097 × v2 + 110 (N) DC 1,5 kV Fm = 0,00228 × v2 + 90 (N)

4.2.16. Dynamic behaviour and quality of current collection

4.2.16.1. 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 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 in accordance with EN 50367:2006, clause 7.2 by assessment of:

— Contact wire uplift and either

— Mean contact force Fm and standard deviation σ max or

— 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 4.2.16.

Table 4.2.16

Requirements for dynamic behaviour and current collection quality

Requirement Category I Category II Category III Space for steady arm uplift 2 S 0 Mean contact force Fm See 4.2.15 Standard deviation at maximum line speed σmax (N) 0,3 Fm Percentage of arcing at maximum line speed, NQ (%) (minimum duration of arc 5ms) ≤ 0,2 ≤ 0,1 for AC systems ≤ 0,2 for DC systems ≤ 0,1

For definitions, values and test methods refer to EN 50317:2002 and EN 50318:2002.

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 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 S 0 (refer to EN 50119:2001 clause 5.2.1.3).

Fm is the dynamically corrected statistical mean value of the contact force.

4.2.16.2. Conformity Assessment

4.2.16.2.1. Interoperability Constituent Overhead Contact Line

A new design of overhead contact line shall be assessed by simulation according to EN 50318:2002 and by measurement of a test section of the new design according to EN 50317:2002.

The simulations shall be made using at least two different TSI compliant (1) 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 4.2.19. In order to be acceptable, the simulated current collection quality shall be within the limits of table 4.2.16 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 4.2.15 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 4.2.16.

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.

4.2.16.2.2. Interoperability Constituent Pantograph

In addition to the pantograph requirements in the Rolling Stock TSI, a new design of a pantograph shall be assessed by simulation according to EN 50318:2002.

The simulations shall be made using at least two different TSI compliant (2) 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 4.2.16 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 EN 50317:2002. The pantograph shall be mounted on a train or locomotive so as to produce a mean contact force as required by clause 4.2.15 for the design speed of the pantograph. The measured current collection quality shall be within the limits of table 4.2.16.

If all the assessments are passed successfully, the tested pantograph design shall be considered as compliant and can be used on various designs of rolling stock provided that the mean contact force on the rolling stock complies with the requirements of clause 4.2.16.1. This aspect is covered by the High Speed Rolling Stock TSI.

4.2.16.2.3. IC OCL in a newly installed line (Integration into a Subsystem)

If the overhead contact line to be installed on a new high-speed line is certificated as an Interoperability Constituent, measurements of the interaction parameters in accordance with EN 50317:2002 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 4.2.15 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 4.2.16. This aspect is covered by this TSI.

4.2.16.2.4. IC Pantograph integrated into new rolling stock

When an approved interoperability constituent pantograph is to be installed on new rolling stock, testing shall be limited to the mean contact force requirements. The tests shall be carried in accordance with EN 50317:2002 or EN 50206-1:1998 (3). The tests shall be conducted in both directions of travel and at the range of nominal contact wire heights as applied for. The measured results shall follow the mean curve, plotted using at least 5 speed intervals for Class 1 trains and at least 3 speed intervals for Class 2 trains. The results shall comply with the curves throughout the speed range for the vehicle, within a range of:

— +0, –10 % for the AC curve C

— +0 %, –10 % for the AC C1 curve (C1 is an upper limit curve)

— +10 %, –0 % for the AC C2 curve (C2 is a lower limit curve)

— +/– 10 % for both the DC Curves

If the tests are passed successfully, the pantograph mounted on that particular train or locomotive can be used on TSI compliant high-speed lines. This aspect is covered by the High Speed Rolling Stock TSI.

4.2.16.2.5. Statistical calculations and simulations

The calculation of statistical values shall be appropriate to the speed of the line, and shall be carried out separately for sections in the open and in tunnels. For the purposes of simulation, the control sections shall be defined so that they are representative including features, for example tunnels, crossovers, neutral sections etc.

4.2.17. Vertical movement of the contact point

The contact point is the point of the mechanical contact between a contact strip and a contact wire.

The vertical height of the contact point above the track shall be as uniform as possible along the span length; this is essential for high-quality current collection.

The maximum difference between the highest and the lowest dynamic contact point height within one span shall be less than the values shown in Table 4.2.17.

This shall be verified by measurements according to EN 50317:2002 or simulations validated according to EN 50318:2002:

— for the maximum line speed of the overhead contact line,

— by using the mean contact force Fm (see clause 4.2.15),

— for the longest span length.

This need not be verified for overlap spans or for spans over switches.

4.2.18. Current capacity of the overhead contact line system: AC and DC systems, trains in motion

The current capacity shall comply at least with the requirements specified for trains according to EN 50388:2005, clause 7.1. The data in EN 50149:2001 shall be used in the design process.

The thermal effects on the overhead contact line system are related to the level of current which is drawn and the time for which that current is drawn. Crosswinds have a cooling effect. The most unfavourable wind conditions on which the calculation of the current capacity shall be based shall be stipulated by the contracting entity.

The design of the overhead contact line system shall ensure that the maximum conductor temperatures specified in EN 50119:2001, annex B are not exceeded, taking account the data given in EN 50149:2001, clause 4.5, Tables 3 and 4 and the requirements of EN 50119:2001 clause 5.2.9. A design study shall be undertaken to confirm that the overhead contact line system complies with the specified requirements.

The overhead contact line of DC systems shall be designed to sustain 300 A for 1,5 kV and 200 A for 3,0 kV, per pantograph (see Annex D).

Permissible temperatures are an open point.

Without other requirements, the contact wire temperature shall not exceed the limits set out in EN 50119:2001, Annex B. The overhead contact line shall be tested using the methodology specified in EN 50367:2006, Annex A.4.1.

Conformity assessment shall be carried out in accordance with EN 50367:2006, clause 6.2.

4.2.21. Phase separation sections

The design of phase separation sections shall ensure that TSI compliant trains (see High Speed Rolling Stock TSI 2006 clause 4.2.8.3.6.2) can move from one section to an adjacent one without bridging the two phases.

Adequate means 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 Infrastructure Register shall contain information on the design of phase separation sections (see Annex D).

Lines of category I

Two types of designs of phase separation sections may be adopted, either:

— a phase separation design where all the pantographs of the longest TSI compliant trains are within the neutral section. The length of the neutral section shall be at least 402 m. For detailed requirements see EN 50367:2006, Annex A.1.3, or

— a shorter phase separation with three insulated overlaps as shown in EN 50367:2006, Annex A.1.5. The overall length of this separation is less than 142 m including clearances and tolerances.

Lines of category II and III

Upon grounds of costs or topographical constraints, it is permissible to adopt various solutions.

For category II and III lines, separation sections as specified for category I lines or a design according to Figure 4.2.21 may be adopted. In the case of Figure 4.2.21, the centre section shall be connected to the current return path, the neutral sections (d) may be formed by insulating rods or double section insulators and the dimensions shall be as follows:

D ≤ 8 m

The length of d shall be chosen in accordance with the system voltage, maximum line speed and the maximum pantograph width.

If the separation sections required for category I lines or the separation section according to Figure 4.2.21 are not used, the Infrastructure Manager shall provide adequate procedures or a design to allow for the passage of trains compliant with the High Speed Rolling Stock TSI. Where an alternative solution is proposed, it shall be demonstrated that the alternative is at least as reliable.

The design of system separation sections shall ensure that TSI compliant trains (see High Speed Rolling Stock TSI 2006 clause 4.2.8.3.6.2) can move from one power supply system to an adjacent different power supply system without bridging the two systems.

There are two possibilities for the train to run through 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. That choice shall be declared in the Infrastructure Register (see Annex D).

4.2.22.2. Pantographs raised

If system separation sections are traversed with pantographs raised to the contact wire, the following conditions apply:

1. the functional design of the system separation section 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, — an example of the arrangement of a system separation section is given in Figure 4.2.22.

2. if the line speed is higher than 250 km/h, the height of the contact wires in both systems shall be the same.

Figure 4.2.22

Example of a system separation section

4.2.22.3. Pantographs lowered

This option shall be chosen if the conditions of operation with pantographs raised can not 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.

For design of system separation sections, conformity assessment shall be carried out within the Energy subsystem.

4.2.23. Electrical Protection Coordination Arrangements

Electrical protection coordination design of the Energy subsystem shall comply with the requirements detailed in EN 50388:2005, clause 11.

4.2.24. Effects of DC operation on AC systems

The fixed installations shall be designed so that they are immune to low value DC currents flowing out of the DC power supply system into the AC power supply system. Immunity from DC current of Open point Amps is required.

4.2.25. Harmonics and Dynamic Effects

The High Speed Energy subsystem shall withstand overvoltages generated by rolling stock harmonics up to the limits stated in EN 50388:2005 clause 10.4. Conformity assessment shall consist of a compatibility study that demonstrates that the subsystem element can withstand harmonics up to the defined limits according to EN 50388:2005, clause 10. Conformity assessment shall be conducted according to EN 50388:2005 clause 10.

For the assessment procedure of the Energy subsystem the Contracting Entity or its authorised representative established within the Community may choose either:

— the unit verification procedure (module SG) indicated in Annex A.2 to this TSI, or

— the full quality management system with design examination procedure (module SH2) indicated in Annex A.2 to this TSI.

The module SH2 may be chosen only where all activities contributing to the subsystem project to be verified (design, manufacturing, assembling, installation) are subject to a quality management system for design, production, final product inspection and testing, approved and surveyed by a Notified Body.

The assessment shall cover the phases and characteristics as indicated in Table C.1 of Annex C to this TSI.

6.2.2.2. Innovative solutions

When an Energy subsystem includes an innovative solution, as defined in section 4.1, the contracting entity shall state the deviation from the relevant section of the TSI and apply for assessment of conformity.

The European Railway Agency shall finalise the appropriate functional and interface specifications of this solution and develop the assessment methods.

The appropriate functional and interface specifications and the assessment methods shall be incorporated in the TSI by the revision process. As soon as these documents are published, the assessment procedure for the subsystem may be chosen by the manufacturer or the contracting entity or his authorised representative established within the Community, as specified in the section 6.2.2.1.

After entry into force of a decision of the Commission, taken in accordance with Article 21(2) of Directive 96/48/EC as modified by Directive 2004/50/EC, the innovative solution may be used before being incorporated into the TSI.

6.2.3. Assessment of maintenance

According to Article 18.3 of Directive 96/48/EC as modified by Directive 2004/50/EC, the Notified Body shall compile the technical file, which includes the maintenance plan.

The Notified Body shall verify only the completeness of the maintenance plan.

The conformity assessment of maintenance is the responsibility of each of the Member State(s) concerned.

6.3. Validity of certificates issued against the previous published version of the TSI

Certificates of conformity already issued against the previous published version of this TSI continue to remain valid in the following cases:

— issued at any stage for interoperability constituents produced or in production, but not yet integrated in a subsystem

— issued at the design stage for interoperability constituents not yet produced

— issued at any stage for subsystems that have been put into service

— issued at the design stage for subsystems not yet put into service

6.4. Interoperable constituents not holding an EC Declaration

6.4.1. General

For a limited period of time, known as the ‘transition period’, interoperability constituents not holding an EC Declaration of Conformity or Suitability for Use may exceptionally be incorporated into subsystems, on the condition that the provisions described in this section are met.

6.4.2. The transition period

The transition period shall commence from the entry into force of this TSI and shall last for six years.

Once the transition period has ended, and with the exceptions allowed under section 6.4.3.3 below, interoperability constituents shall be covered by the required EC declaration of conformity and/or suitability for use before being incorporated into the subsystem;

6.4.3. The certification of subsystems containing non-certified interoperability constituents during the transition period

6.4.3.1. Conditions

During the transition period a Notified Body is permitted to issue a certificate of conformity 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 three criteria are complied with:

— the conformity of the subsystem has been checked in relation to the requirements defined in chapter 4 of this TSI by the Notified Body, and

— through carrying out additional assessments the Notified Body confirms that the conformity and/or the suitability for use of the interoperability constituents is in accordance with the requirements of chapter 5, and

— the interoperability constituents, which are not covered by the relevant EC declaration of conformity and/or suitability for use, shall have been used in a subsystem already put in service in at least one of the Member States 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.

6.4.3.2. Notification

— the certificate of conformity 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.

6.4.3.3. Lifecycle Implementation

The production or upgrade/renewal of the subsystem concerned must be completed within the six years of the transition period. Concerning the subsystem lifecycle:

— During the transition period and

— under the responsibility of the body having issued the declaration of EC verification of the subsystem

the interoperability constituents which do not hold an EC declaration of conformity and/suitability for use and are of the same type built by the same manufacturer are permitted to be used for maintenance related replacements and as spare parts for the subsystem.

After the transition period has ended and

— until the subsystem is upgraded, renewed or replaced and

— under the responsibility of the body having issued the declaration of EC verification of the subsystem

the interoperability constituents which do not hold an EC declaration of conformity and/or suitability for use and are of the same type built by the same manufacturer may continue to be used for maintenance related replacements.

6.4.4. Monitoring arrangements

During the transition period Member States shall monitor:

— The number and type of interoperability constituents introduced on the market within their own State;

— Ensure that, where a subsystem is presented for authorisation, reasons for non-certification of the interoperability constituent by the manufacturer are identified;

— Notify, to the Commission and to the other Member States, the details of the non-certified IC and the reasons for non-certification.

7. IMPLEMENTATION OF THE ENERGY TSI

7.1. Application of this TSI to new high-speed lines being put into service

Chapters 4 to 6 and any specific provisions in paragraph 7.4 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.

7.2. Application of this TSI to high-speed lines already in service

7.2.1. Introduction

In respect of infrastructure installations already in operation, this TSI applies to sections of line being upgraded or renewed under the conditions specified in Article 14.3 of Directive 96/48/EC as modified by Directive 2004/50/EC. In this particular context, it relates fundamentally to the application of a migration strategy which enables an economically justifiable adaptation of existing Energy installations to be made.

Whilst the TSI can be fully applied to new installations, implementation on existing lines may require modifications of existing equipment. The degree of modification necessary will depend on the extent of conformity of the existing equipment. The following principles apply in the case of the High Speed Energy TSI, without prejudice to clause 7.4 (Specific cases). When the Member State requires a new putting into service, the Contracting Entity shall define the practical measures and different phases which are necessary to achieve the required levels of performance. These phases may include transition periods for placing into serv
