(notified under document number C(2002) 1949)

(Text with EEA relevance)

(2002/733/EC)

THE COMMISSION OF THE EUROPEAN COMMUNITIES,

Having regard to the Treaty establishing the European Community,

Having regard to Council Directive 96/48/EC of 23 July 1996 on the interoperability of the trans-European high-speed rail network(1), and in particular Article 6(1) thereof,

Whereas:

(1) In accordance with Article 2(c) of Directive 96/48/EC, the trans-European high-speed rail system is subdivided into structural or functional subsystems. These subsystems are described in Annex II to the Directive.

(2) In accordance with Article 5(1) of the Directive, each of the subsystems shall be covered by a technical specification for interoperability (TSI).

(3) In accordance with Article 6(1) of the Directive, draft TSIs shall be drawn up by the joint representative body.

(4) The Committee set up under Article 21 of Directive 96/48/EC has appointed the European Association for Railway Interoperability (AEIF) as the joint representative body in accordance with Article 2(h) of the Directive.

(5) The AEIF has been given a mandate to draw up a draft TSI for the energy subsystem in accordance with Article 6(1) of the Directive. This mandate has been established in accordance with the procedure laid down in Article 21(2) of the Directive.

(6) The AEIF has drawn up the draft TSI, together with an introductory report containing a cost-benefit analysis as provided for in Article 6(3) of the Directive.

(7) The draft TSI has been examined by the representatives of the Member States, in the framework of the Committee set up by the Directive, in the light of the introductory report.

(8) As specified in Article 1 of Directive 96/48/EC, the conditions for achieving interoperability of the trans-European high-speed rail system concern the design, construction, upgrading and operation of the infrastructures and rolling stock contributing to the functioning of the system to be put into service after the date of entry into force of the Directive. With regard to the infrastructures and rolling stock already in service at the time of entry into force of this TSI, the TSI should be applied from the time when work is envisaged on these infrastructures. However, the degree to which the TSI is applied will vary according to the scope and extent of the works foreseen and the costs and the benefits generated by the intended applications. In order for such partial works to concur into achieving full interoperability, they need to be underpinned by a coherent implementation strategy. In this context, a distinction should be made between upgrading, renewal and maintenance-related replacement.

(9) It is recognised that Directive 96/48/EC and the TSIs do not apply to renewals or maintenance-related replacement. It is desirable however that the TSIs should apply to renewals - as will be the case for the TSIs for the conventional rail system under Directive 2001/16/EC. In the absence of a mandatory requirement and taking into account the extent of the renewal work, Member States are encouraged, where they are able to do so, to apply the TSIs to renewals and maintenance-related replacement.

(10) In its current version, the TSI, which is the subject of this Decision, covers features specific to the high-speed system; as a general rule, it does not address the common aspects of the high-speed and conventional rail system. The interoperability of the latter is the subject of another directive(2). Given that verification of interoperability has to be established by reference to the TSIs, in accordance with Article 16(2) of Directive 96/48/EC, it is necessary, during the transition period between the publication of this Decision and the publication of the Decisions adopting the "conventional rail" TSIs, to lay down the conditions to be complied with in addition to the TSI attached. For these reasons it is necessary that each Member State inform the other Member States and the Commission of the relevant national technical rules in use for achieving interoperability and meeting the essential requirements of Directive 96/48/EC. In addition, those rules being national, it is necessary that each Member State inform the other Member States and the Commission of the bodies it appoints for carrying out the procedure for the assessment of conformity or suitability for use as well as the checking procedure in use for verifying the interoperability of subsystems within the meaning of Article 16(2) of Directive 96/48/EC. Member States shall apply, as far as possible, the principles and criteria provided for in Directive 96/48/EC for the implementation of Article 16(2) in the case of those national rules. As to the bodies in charge of those procedures, Member States will make use, as far as possible, of bodies notified under Article 20 of Directive 96/48/EC. The Commission will carry out an analysis of this information (national rules, procedures, bodies in charge of implementing procedures, duration of these procedures) and, where appropriate, will discuss with the Committee the necessity of any measure to be taken.

(11) The TSI, which is the subject of this Decision, does 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.

(12) The TSI, which is the subject of this Decision, is based on best available expert knowledge at the time of preparation of the corresponding draft. Developments in technology or social requirements may make it necessary to amend or supplement this TSI. Where appropriate, a review or updating procedure will be initiated in accordance with Article 6(2) of Directive 96/48/EC.

(13) In some cases, the TSI, which is the subject of this Decision, allows a choice between different solutions, making it possible to apply definitive or transitional interoperable solutions that are compatible with the existing situation. In addition, Directive 96/48/EC provides for special implementing provisions in certain specific cases. Furthermore, in the cases provided for in Article 7 of the Directive Member States must be allowed not to apply certain technical specifications. It is therefore necessary that the Member States ensure that an infrastructure register and a rolling stock register are published and updated each year. These registers will set out the main characteristics of the national infrastructure and rolling stock (e.g. the basic parameters) and their concordance with the characteristics prescribed by the applicable TSIs. To this end, the TSI, which is the subject of this Decision, indicates precisely which information must appear in the register.

(14) The application of the TSI which is the subject of this Decision must take into account specific criteria relating to technical and operational compatibility between the infrastructures and the rolling stock to be placed in service and the network into which they are to be integrated. These compatibility requirements entail a complex technical and economical analysis that is to be done on a case-by-case basis. The analysis should take into account:

- the interfaces between the different subsystems referred to in Directive 96/48/EC,

- the different categories of lines and rolling stock referred to in that Directive and

- the technical and operational environments of the existing network.

That is why it is essential to establish a strategy for the implementation of the TSI which is the subject of this Decision, which should indicate technical stages to move from the present network conditions to a situation where the network is interoperable.

(15) The provisions of this Decision are in conformity with the opinion of the Committee set up by Directive 96/48/EC,

HAS ADOPTED THIS DECISION:

Article 1

The TSI relating to the "energy" subsystem of the trans-European high-speed rail system referred to in Article 6(1) of Directive 96/48/EC is hereby adopted by the Commission. The TSI is set out in the Annex to this Decision. The TSI is fully applicable to the infrastructure and rolling stock of the trans-European high-speed rail system as defined in Annex I to Directive 96/48/EC, taking into account Article 2 and Article 3 hereunder.

Article 2

1. With regard to the aspects that are common to the high-speed and the conventional rail systems, but not covered in the attached TSI, the conditions to be complied with for the verification of the interoperability within the meaning of Article 16(2) of Directive 96/48/EC are the applicable technical rules in use in the Member State which authorises the placing in service of the subsystem concerned by this Decision.

2. Each Member State shall notify to the other Member States and to the Commission within six months of the notification of this Decision:

- the list of the applicable technical rules mentioned under Article 2(1),

- the conformity assessment and checking procedures to be applied with regard to the application of these rules,

- the bodies it appoints for carrying out those conformity assessment and checking procedures.

Article 3

1. For the purposes of this Article:

- "upgrading" means major work to modify a subsystem or part of a subsystem which changes the performance of the subsystem,

- "renewal" means major work to replace a subsystem or part of a subsystem which does not change the performance of the subsystem,

- "maintenance related replacement" means replacement of components by parts of identical function and performances in the context of predictive or corrective maintenance.

2. In the case of upgrading, the contracting entity will submit a dossier describing the project to the Member State concerned. The Member State will examine the dossier and, taking into account the implementation strategy in Chapter 7 of the attached TSI, will (where appropriate) decide whether the scale of the work requires the need for a new authorisation for placing in service under Article 14 of Directive 96/48/EC. Such authorisation for placing in service is necessary whenever the level of safety may objectively be affected by the work envisaged.

Where a new authorisation for placing in service under Article 14 of Directive 96/48/EC is necessary, the Member State decides whether:

(a) the project includes full application of the TSI, in which case the subsystem will be subject to the EC verification procedure in Directive 96/48/EC; or

(b) full application of the TSI is not yet possible. In this case the subsystem will not be in full conformity with the TSI and the EC verification procedure in Directive 96/48/EC shall be applied only in respect of the parts of the TSI applied.

In these two cases the Member State will inform the Committee set up pursuant to Directive 96/48/EC of the relevant dossier including the parts of TSI being applied and the degree of interoperability being achieved.

3. In the case of renewal and maintenance-related replacement, application of the attached TSI is voluntary.

Article 4

The relevant parts of Commission Recommendation 2001/290/EC(3) on the basic parameters of the trans-European high-speed rail system no longer have effect from the date of entry into force of the attached TSI.

Article 5

The attached TSI shall enter into force six months after notification of this Decision.

ANNEX

TECHNICAL SPECIFICATION FOR INTEROPERABILITY RELATING TO THE ENERGY SUBSYSTEM

1. INTRODUCTION

1.1. Technical scope

This TSI concerns the energy subsystem, which is one of the subsystems listed in Annex II(1) to Directive 96/48/EC.

This TSI is part of a set of six TSIs, which cover all eight subsystems defined in the Directive. The specifications concerning the "users" and "environment" subsystems, which are necessary to ensure interoperability of the trans-European high-speed rail system in compliance with the essential requirements, are set out in the TSIs concerned.

More information about the energy subsystem is given in Chapter 2.

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.

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 on Community guidelines for the development of the trans-European transport network or in any 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 and with Annex I(1)(b) to Directive 96/48/EC, this TSI:

(a) specifies the essential requirements for the subsystems and their interfaces (Chapter 3);

(b) establishes the basic parameters described in Annex II(3) to that Directive, which are necessary to meet the essential requirements (Chapter 4);

(c) establishes the conditions to be complied with to achieve the specified performances for each of the following categories of line (Chapter 4):

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

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

- category III: specially upgraded high-speed lines which have special features as a result of topographical, relief or town-planning constraints, on which the speed must be adapted to each case.

(d) establishes implementing provisions in certain specific cases (Chapter 7);

(e) determines the interoperability constituents and interfaces which must be covered by European specifications, including European standards, which are needed in order to achieve interoperability within the trans-European high-speed rail system while meeting the essential requirements (Chapter 5);

(f) states, in each case under consideration, which of the modules defined in Decision 93/465/EEC or, where appropriate, which specific procedures are to be used in order to assess either the conformity or the suitability for use of the interoperability constituents, as well as "EC" verification of the subsystems (Chapter 6).

2. SUBSYSTEM DEFINITION/SCOPE

2.1. Scope

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 consists of:

- substations: they are 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 their secondary side substations are connected to the railway overhead contact lines,

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

- overhead contact lines: the overhead contact lines distribute the energy to the trains running on the route and transmit it to the trains by means of pantographs. The overhead contact line is also equipped with manually or remotely controlled disconnectors which are required to isolate sections or groups of the overhead contact lines depending on the operational necessities. All types of feeder lines belong to the contact lines as well,

- current return circuit: the traction current utilises rails, which are connected directly or indirectly to earth, and return conductors, to flow back to the substations. Therefore, so far as this aspect is concerned, the current return circuit is part of the energy subsystem.

- pantograph: despite being installed on moving rolling stock the pantographs form an important device the proper function of which is directly linked to the overhead contact line. Therefore, it is considered to be part of the energy subsystem,

The following aspects of the energy subsystem are related to the interoperability of the trans-European high-speed rail system:

- electrification system,

- overhead contact lines and pantographs,

- interaction of pantographs and overhead line equipment,

- boundaries between high-speed lines, upgraded lines and connecting lines.

2.2. Definition of the subsystem

2.2.1. Electrification system

As with any electrical device a traction unit is designed in order to operate correctly with a nominal voltage and a nominal frequency applied at its terminals that are the pantographs and wheels. Variations and limits of these parameters need to be defined to guarantee the anticipated performance of the train.

High-speed trains need a correspondingly high power. Therefore, in order to supply the trains with minimum losses it is necessary to increase the voltage of the supply system and decrease the current that gives rise to the resistive losses. 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 use regenerative braking sending back energy to the power supply to reduce the overall power consumption. Therefore, the power supply system has to accept regenerative braking as well.

In any electrical system short-circuits and other fault conditions may occur. The electrification system needs to be designed such that the subsystem control detects these faults immediately and triggers measures to remove the short-circuit current and isolate the defect 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. Overhead contact line and pantograph

From the interoperability point of view, the geometry of the overhead contact line equipment and of the pantographs is an important aspect. So far as the geometrical interaction is concerned the height of the contact wire above the rails, the lateral displacement in still air and under wind pressure and the contact force have to be specified. For the pantograph the geometry of the collector head is also fundamental in order to guarantee correct interaction with the contact line whilst taking into account the possible sway of the vehicles.

2.2.3. Interaction of overhead line and pantograph

At the high speeds envisaged for the trans-European high-speed rail system the interaction of the overhead contact line and the pantograph represents a very important aspect in establishing a reliable power transmission without undue disturbances to railway installations and of the environment. This interaction is mainly determined by:

- static and aerodynamic efforts depending on the nature of the contact strip of the pantograph and the design of the pantographs,

- the compatibility of the contact strip material with the contact wire regarding limitation of wear on those components,

- the dynamic behaviour and impacts on the current collection quality and the aim of a continuous, uninterrupted power supply without disturbances,

- the protection of the pantograph and overhead contact line equipment in case of a broken pantograph collector strip,

- the number of pantographs in service and the distance between them which have a fundamental impact on the collection quality since each pantograph can interfere with others on the same contact line.

2.2.4. Boundaries between high-speed lines and other lines

High-speed lines have to be linked to upgraded lines or to connecting lines. The location of the boundaries between these types of line affects the power supply and 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 many links with other subsystems of the trans-European high-speed rail system in order to achieve the envisaged performance of interoperability. 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 rolling stock subsystem.

- The power installed on the lines and the specified power factor determine the performance of the interoperable high-speed rail system and interface with the rolling stock subsystem.

- Regenerative braking reduces energy consumption and interfaces with the rolling stock subsystem.

- Electrical fixed installations and on-board traction equipment need to be protected against short circuits by appropriate devices in substations. Tripping of circuit breakers in substations and on trains has to be coordinated; that is why electric protection interfaces with the rolling stock subsystem.

- Electric interference and harmonic emissions interface with the rolling stock and control-command and signalling subsystems.

2.3.3. Links concerning overhead contact line equipment and pantographs

- In the case of high-speed lines the contact wire height needs special attention in order to avoid excessive wear of the contact wire. The contact wire height interfaces with the infrastructure and rolling stock subsystems.

- To pass boundaries of electrification systems without bridging differing systems the number and arrangement of pantographs on trains have to be stipulated. They interface with the rolling stock subsystem.

- The possible sway of vehicles and pantographs interfaces with the rolling stock and infrastructure subsystems.

2.3.4. Links concerning interaction of overhead line and pantograph

- The quality of current collection depends on the number of pantographs in service and their spacing. The arrangement of pantographs interfaces with the rolling stock subsystem.

3. ESSENTIAL REQUIREMENTS

4. CHARACTERISATION OF THE SUBSYSTEM

The trans-European high-speed rail system, to which Directive 96/48/EC applies and of which the Energy subsystem is a part, is an integrated system which requires the basic parameters, interfaces and performances to be verified in particular so as to ensure that the system is interoperable and that the essential requirements are met.

4.1. Basic parameters of the Energy subsystem

4.1.1. Voltage and frequency

Train services need standardisation of the voltage and frequency values as stipulated for interoperability. Table 4.1 lists the voltages and frequencies applicable depending on the line category.

Table 4.1

Voltages and frequencies

>TABLE>

The voltage at the terminals of the substation and at the pantograph shall comply with Annex N to this TSI. The frequency of the voltage shall comply with Annex N to this TSI. Voltage and frequencies will be defined in the register of infrastructure (Annex D to this TSI). For conformity assessment see Annex N4.

4.1.2. Overhead line and pantograph

On future high-speed, upgraded and connecting lines there should be only one type of current collector head used for all trains running on these lines. To implement this approach, all future high-speed trains will use pantographs with a 1600 mm pantograph collector head. All newly built AC high-speed overhead line equipment shall comply with points 4.1.2.1 and 4.1.2.3, respectively. This also concerns upgraded and connecting AC and DC lines.

4.1.2.1. Geometry of overhead contact line for AC systems

The height of contact wire above the rails, the gradient of contact wire in relation to the track and the lateral deflection of the contact wire under the action of a cross wind all govern the interoperability of the high-speed network. The permissible data are given in Table 4.2.

Table 4.2

Geometry of overhead contact lines for AC systems

>TABLE>

The overhead contact line geometry shall comply with the requirements set in Annex H.3.1 to this TSI.

4.1.2.2. Geometry of overhead contact line for DC systems

The data determining the geometry of overhead contact line for DC systems within the trans-European interoperable rail network is stipulated in Table 4.3.

Table 4.3

Geometry of overhead contact lines for DC systems

4.2.2.1. Gauges

The infrastructure gauge shall take into account the space necessary for the passage of pantographs in contact with the overhead contact line equipment and for installation of the contact line equipment itself. The dimensions of tunnels and other structures shall be mutually compatible with the geometry of overhead line equipment and the dynamic envelope of the pantograph. (Annex (H.3.6) to this TSI specifies the dynamic envelope of the pantograph). The space necessary for installation of the contact line equipment shall be stipulated by the adjudicating entity. Conformity assessment shall be carried out within assessment of the Infrastructure subsystem.

4.2.2.2. Earthing and bonding, protection against electric shock

Infrastructure subsystem shall implement a general earthing system along the route to comply with the requirements for protection against electric shock specified in EN 50122-1. Protection against electric shock during operation and in failure conditions is met by limiting touch voltages to acceptable limits as stipulated in EN 50122-1, version 1997, point 7. Results of investigations carried out by the adjudicating entity and the corresponding specific provisions shall be provided to demonstrate the compliance with the requirements. Conformity assessment shall be carried out within the assessment of infrastructure subsystem.

4.2.2.3. Harmonic currents, influence on signalling and internal telecommunications

Harmonic currents generated by rolling stock affect the control-command and signalling subsystem through the energy subsystem. That is why this subject is dealt within the control-command and signalling subsystem. No conformity assessment is required by the energy subsystem.

4.2.2.4. Vehicle dynamic envelope

Overhead line equipment design shall comply with the dynamic envelope of the vehicles. The gauge to be adopted depends on the category of line defined in the register of infrastructure (Annex D to this TSI). Conformity assessment shall be carried out within the energy subsystem.

4.2.2.5. Limitation of maximum power consumption

The installed power on a high-speed line and upgraded or a connecting line determines the permissible power consumption of trains. Therefore, current limitation devices shall be installed on board as described in Annex O to this TSI. Assessment shall be carried out within assessment of the rolling stock subsystem. The register of infrastructure defined in Annex D to this TSI shall contain information on maximum power consumption.

4.2.2.6. Limitation of current drawn by trains at standstill

In case of DC 1,5 kV and 3,0 kV systems the current at standstill shall be limited to 300 A and 200 A, respectively, per pantograph. Assessment shall be carried out within assessment of the rolling stock subsystem.

4.2.2.7. Voltage and frequency

Trains shall be able to operate within the range of voltages and frequencies as given in point 4.1.1 and specified in Annex N to this TSI. Conformity assessment shall be carried out within assessment of the rolling stock subsystem.

4.2.2.8. Electrical protection coordination

Coordination between the electrical protection of substations and that of traction units is necessary to optimise the clearance of shortcircuits. (Annex E to this TSI gives the applicable requirements.) The register of infrastructure defined in Annex D to this TSI shall contain information on protection of substations.

Conformity assessment shall be carried out with the energy subsystem in so far as design and operation of substation is concerned and with the rolling stock subsystem in so far as equipment on traction units is concerned.

4.2.2.9. Arrangement of pantographs

The arrangement of pantographs on trains shall take care of the maximum train length. The maximum distance between pantographs is less than 400 m. In addition the spacing between three consecutive pantographs shall be more than 143 m. The acceptable number of pantographs and their spacing depend also on the dynamic performance. The pantographs shall not be linked electrically in case of AC power supply systems. Reference is made to Annex H (H.3.5) to this TSI.

Conformity assessment shall be carried out with the rolling stock subsystem.

4.2.2.10. Running through phase separation sections

Trains shall be able to 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 underneath the phase separation to be restarted. For design, reference is made to Annex H(H.3.3), to this TSI.

The register of infrastructure defined in Annex D to this TSI shall contain information on the design of phase separation sections.

Power consumption (traction and auxiliaries) of the train shall be brought to zero when entering the phase separation section. This shall be done automatically without the driver's intervention. Lowering of the pantographs is not necessary.

Requirements for design of energy subsystem

For future lines two types of designs of phase separation sections may be adopted:

- a phase separation design where all the pantographs of the longest interoperable trains are inside the neutral section. In this case there is no restriction for the arrangement and spacing of the pantographs on the trains. The length of the neutral section shall be at least 402 m. For detailed requirements see Annex H(H.3.3) to this TSI,

- a shorter phase separation with a restriction for pantograph arrangement on trains is shown in Annex H(H.3.3) to this TSI. The overall length of this separation is less than 142 m. Using this design necessitates that the distance between three consecutive pantographs in service is more than 143 m.

For existing lines various solutions might be adopted and based on the accepted arrangement of pantographs on the train, depending on the possibilities of route planning, required performance and investments acceptable to the adjudicating entity. If the design of existing phase separations does not permit the passage of interoperable high-speed trains, then the adjudicating entity shall provide adequate alternative procedures or designs.

Information on the design of phase separation sections shall be provided by the register of infrastructure as defined in Annex D to this TSI.

For design of phase separation section, conformity assessment shall be carried out within assessment of the energy subsystem.

Requirements for control-command and rolling stock subsystems

On high-speed lines, the control-command and signalling subsystem shall allow the rolling stock to operate automatically before and after phase separation sections. Equipment on traction units shall be triggered in due time in front of a phase separation section taking full account of the maximum permissible running speed. For conformity assessment functional tests shall be carried out jointly with rolling stock and control-command and signalling subsystems.

4.2.2.11. Running through system separation sections

General

Trains shall be able to move from one energy supply system to an adjacent one that uses a different energy supply without bridging the two systems. The necessary actions depend on the type of both supply systems as well as on the arrangement of pantographs on trains and the running speed.

There are two possibilities for the train to run through system separation sections:

(1) with pantograph raised and touching the contact wire,

(2) with pantograph lowered and not touching the contact wire.

A choice has to be made by the adjudicating entity and declared in the register of infrastructure defined in Annex D to this TSI.

Requirements for the design of energy subsystem

- Pantographs raised

If system separation sections are negotiated 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 with the arrangement of pantographs specified in point 4.2.2.9,

- for short neutral section, the mechanical behaviour of the pantograph overhead contact line system shall comply with the EN 50119, version 2001, point 5.2, at maximum speed,

- provisions shall be taken in the energy subsystem to avoid bridging of both adjacent power supply systems when the opening of the on-board circuit breaker(s) fails,

- an example for arrangement of system separation section is given in figure H.4 of Annex H to this TSI;

(2) the height of the contact wires in both systems has to be the same, if the speed is more than 250 km/h. Details and tolerances are given in Annexes H and J to this TSI;

(3) on rolling stock, devices shall open automatically the circuit breaker before reaching the separation section and recognise automatically the voltage of the new power supply system at the pantograph in order to switch the corresponding circuits.

- Pantographs lowered

If the system separation sections are negotiated with pantographs down the following conditions apply:

(1) the design of the separation section between differing energy supply systems shall ensure that, in case of an unintentional pantograph at the contact line, bridging of the two power supply systems is avoided and switching off both supply sections is triggered immediately. Triggering of a short circuit ensures operation of insulated sections;

(2) this alternative choice has to be made if the conditions of operation with pantographs raised are not complied with;

(3) on high-speed lines with different heights of contact wire and on separation sections of existing lines not complying with the TSI requirements, pantographs shall be lowered when the energy supply system changes or when the running speed does not permit the installation of transition sections with acceptable gradients (see Annexes H and J to this TSI);

(4) at supply system separations which require a lowering of the pantograph, the pantograph shall be lowered without the driver's intervention, triggered by control signals.

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

Requirements for control-command and rolling stock subsystems

Before running through separation sections between different energy supply systems the traction units' main circuit breaker shall be opened without the driver's intervention, triggered by control signals. This shall be carried out in good time so that the traction unit electrical equipment for the terminating energy supply system fully shuts down before the new energy supply system is reached.

The control-command and signalling subsystem shall provide the required signals to the traction units.

The traction units shall be designed so that they are able to receive line control signals to trigger the opening of the main circuit breaker and lower the pantographs if required without the driver's intervention. When pantographs are not lowered from the contact wire, only those electric circuits on the traction units which instantaneously conform to the energy supply system at the pantograph may remain connected.

The design and the operation of system separation sections shall be explained in the register of infrastructure defined in Annex D to this TSI.

Conformity assessment shall be carried out with functional tests jointly with control-command and rolling stock subsystems.

4.2.2.12. Adjustment of pantograph contact force

Rolling stock shall permit by internal controls adjustment of pantograph contact force to comply with the requirements specified in point 5.3.2.7. Conformity assessment shall be carried out within the rolling stock subsystem.

4.3.1.8. Protection against electric shock

The energy supply system shall be integrated into the general earthing system along the line to comply with the requirements for protection against electric shock as specified in EN 50 122-1, version 1997, points 5, 7 and 9. Protection against electric shock during operation and in failure conditions is met by limiting touch voltages to acceptable limits as stipulated in EN 50 122-1, version 1997, points 7.2 and 7.3. For each installation a study shall be established to prove the protection against electric shock. The study may include tests.

4.3.1.9. Maintenance plan

Maintenance procedures should not downgrade safety provisions such as continuity of return current circuit, limitation of overvoltages and detection of short circuits. It shall not reduce the global performance of the system and avoid de-energising of any part of the overhead contact line.

4.3.1.10. Isolation of power supply in case of danger

Equipment shall be installed and procedures implemented to initiate isolation of voltage from traction units and electrified lines through alarm devices allowing the power supply operator to carry out emergency actions. Conformity assessment shall be carried out by checking the transmission devices and instructions for procedures.

4.3.1.11. Continuation of power supply in case of disturbances

The power supply and the overhead contact line shall be designed to enable continuation of operation in case of disturbances. This can be achieved by sectioning contact lines into supply sections and installation of redundant equipment in substations. Conformity assessment shall be carried out by checking the circuit diagrams.

4.3.2. Performance of the overhead contact line

4.3.2.1. General

The performance to be achieved by the overhead contact line shall correspond to the relevant performance as specified for each category of lines of the trans-European high-speed rail system in function of

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.

The collection quality may be assessed by the mean value Fm and the standard deviation σ of measured or simulated contact forces or by counting of arcing. For AC systems the criteria are listed in Table 4.5 and for DC systems in Table 4.6.

The adjudicating entity shall decide to use interaction criterion item No 1 (contact force) or item No 2 (arcing) according to Table 4.5 or 4.6.

The interaction is considered to comply with the provisions in this TSI if

- item 1 or 2 of Table 4.5, and

5. INTEROPERABILITY CONSTITUENTS

5.1. General

According to Article 2(d) of Directive 96/48/EC interoperability constituents are: "any elementary component, group of components, subassembly or complete assembly of equipment incorporated or intended to be incorporated into a subsystem, upon which the interoperability of the trans-European high-speed rail system depends either directly or indirectly".

The interoperability constituents are covered by the relevant provisions of Directive 96/48/EC and are listed in section 5.2 of this TSI so far as the Energy subsystem is concerned.

5.2. Definitions of interoperability constituents

In case of the Energy subsystem the following constituents are defined:

- overhead contact line: an overhead contact line is a contact line placed above the upper limit of the vehicle gauge and supplying vehicles with electric energy through roof-mounted current collection equipment referred to as pantographs. In the case of high-speed rail systems overhead contact lines with catenary suspension are applied where the contact wire(s) is/are suspended from one or more longitudinal catenaries. The supporting components such as cantilevers, masts and foundations will not affect the interoperability and, therefore, are not covered by this TSI,

- pantograph: pantographs are devices for collecting currents from one or more contact wires formed by a hinged device designed to allow vertical movement of the pantograph head. The pantograph head carries the contact strips and their mountings. The end of the pantograph head is formed by a down-turned horn,

- contact strips: contact strips are the replaceable parts of the pantograph head which are in direct contact with the contact wire and as a consequence are prone to wear.

5.3. Characterisation of constituents

5.3.1. Overhead contact line

5.3.1.1. Overall design

Design of overhead contact lines shall comply with EN 50119, version 2001, points 5 and 6. Additional requirements, specially concerning high-speed lines are specified hereafter.

The overhead contact line shall meet the specified performance for the specific line especially so far as the maximum running speed and the current carrying capacity are concerned.

5.3.1.2. Current capacity

The current capacity depends on the ambient conditions which are maximum ambient temperature and minimum cross-wind speed defined for each specific line in the register of infrastructure defined in Annex D to this TSI as well as the permissible temperatures of the contact line elements and the duration of current action. The design of the overhead contact line shall take care of the limits for the maximum temperatures as specified in Annex B to EN 50119, version 2001, taking account of the data given in EN 50149, version 1999, point 4.5, Tables 3 and 4. An analysis shall prove that the contact line is able to comply with the specified requirements.

5.3.1.3. Basic parameters

The design of the overhead contact line shall comply with the basic parameters as specified in points 4.1.2.1 and 4.1.2.2.

5.3.1.4. Wave propagation speed

The speed of wave propagation on contact wires is a characteristic parameter for assessing the suitability of a contact line for a high-speed operation. This parameter depends on the specific mass and the stress of the contact wire. Maximum operation speed shall not be more than 70 % of the wave propagation speed. See also EN 50119, version 2001, point 5.2.1.4.

5.3.1.5. Elasticity and uniformity of elasticity

Elasticity and the uniformity along the span are essential for a high-quality current collection and a reduction of wear and tear. The uniformity of elasticity can be assessed by the uniformity factor u

>REFERENCE TO A GRAPHIC>

where:

emax maximum elasticity along a span,

emin minimum elasticity along a span.

In case of high-speed lines a parameter u as low as possible should be aimed at; Table 5.1 gives limit values for u, which are accepted for each type of overhead contact line.

Table 5.1

Uniformity u of elasticity in %

>TABLE>

For high-speed lines the mid-span elasticity should be limited to values less than 0,5 mm/N. The contact line shall comply with EN 50119, version 2001, point 5.2.1.3.

5.3.1.6. Mean contact force

This clause stipulates mean contact forces for which the contact line shall be designed.

Figure 5.1

Target for mean contact force Fm for AC systems depending on running speed

>PIC FILE= "L_2002245EN.030301.TIF">

The mean contact force Fm formed by the static and aerodynamic components of the contact force with dynamic correction which shall be applied on the contact wire is shown in figure 5.1 for AC systems as a function of running speed.

In this context Fm represents a target value which should be achieved to ensure on one hand a current collection without undue arcing and which should not be exceeded on the other hand to limit wear and hazards to current collection strips.

In case of trains with multiple pantographs simultaneously in operation the mean contact force Fm for any pantograph shall be not higher than the value given by figure 5.1 since for each individual pantograph the current collection criteria shall be met.

Concerning DC systems, the mean contact force Fm formed by the static and aerodynamic components of the contact force with dynamic correction which shall be applied for DC 1,5 kV and DC 3,0 kV systems is shown in fig. 5.2 as a function of running speed. For DC 1,5 kV lines the static contact force should be 140 N where necessary in respect of the current at standstill.

In case of trains with multiple pantographs simultaneously in operation the mean contact force Fm for any pantograph shall be not higher than the value given by figure 5.2 since for each individual pantograph the current collection criteria shall be met.

5.3.1.7. Maintenance

The manufacturer shall provide any necessary information to allow the adjudicating entity to draft a plan concerning maintenance taking into account especially the geometry of the overhead line, the wear of the contact wire, especially at critical points such as crossings, switches and overlaps.

5.3.1.8. Current at standstill

An acceptable level of current at standstill shall be acceptable for both the contact wire and pantograph collector strips to allow a proper feeding of the auxiliaries installed on board trains. For DC 1,5 kV systems a current of 300 A per pantograph shall be guaranteed, while for DC 3,0 kV systems a current of 200 A per pantograph shall be guaranteed. When testing the overhead contact line with the methodology specified in EN 50206-1, version 1998, point 6.13, the contact wire temperature shall not exceed the limits given in Annex B to EN 50119, version 2001.

5.3.2. Pantograph

5.3.2.1. Overall design

The pantograph shall meet the specified performance as far as maximum running speed and current carrying capacity are concerned. So far as not specified hereafter EN 50206 applies. The installation of pantograph on rolling stock is dealt with by the rolling stock subsystem.

5.3.2.2. Basic parameters

The design of the pantograph shall meet the basic parameters as specified in section 4.1.

5.3.2.3. Current capacity

The pantograph shall be designed for the specified current to be transmitted to the vehicles. The rated current shall be provided by the manufacturer. Attention shall be given especially to the specific data depending on the use on AC or DC systems. An analysis shall prove that the pantograph is able to carry the specified current.

5.3.2.4. Design of insulation

The pantographs shall be assembled on the roof of the vehicles insulated against earth. The design of insulation shall take care of the stresses by voltage. References for data to be verified are in Annex N to this TSI for system voltages and EN 50124-1, version 1999, Table 2, for insulation coordination requirements. Insulators shall be tested according to EN 60383.

5.3.2.5. Working range of pantographs

The pantographs shall be able to work under contact wire heights between 4800 mm and 6400 mm. For operation in the UK and Finland on upgraded or connecting lines, the height is different. See section 7.3.

5.3.2.6. Static contact force

Static force is the mean vertical contact force exerted upward by the collector head on the contact line and caused by the pantograph raising device, whilst the pantograph is raised and the vehicle is at standstill.

For AC systems the static force shall be adjustable between 40 N and 120 N.

In DC systems to improve the contact of collector strips with the contact wire, a higher force may be needed to avoid dangerous heating of the contact wire when the train is at standstill with its auxiliaries working. For DC systems the static force shall be adjustable between 50 and 150 N.

The pantographs and their mechanisms that provide the necessary contact forces shall ensure that the pantographs can be used on every type of interoperable overhead contact line. For details and assessment reference is made to EN 50206-1, version 1998, point 6.3.1

5.3.2.7. Mean contact force and interaction performance of the overhead line/pantograph system

The mean contact force is the mean value of the forces due to static and aerodynamic actions. It is equal to the sum of static contact force (point 5.3.2.6) and the aerodynamic force caused by the airflow on the pantograph elements at the considered speed. The mean uplift force is a characteristic of the pantograph for given rolling stock and a given development of the pantograph. The mean contact force is measured at the collector head according to Annex Q(Q.4.2.2).

The value of mean contact force shall comply with the mean contact force F stipulated in point 5.3.1.6.

For existing, connecting, upgraded and high-speed AC lines which would not comply with the requirements stipulated in point 5.3.1.6, the pantograph shall be designed such that the running speed-dependent mean contact force Fm, in addition to the target curve according to figure 5.1, allows other adjustment curves C1 and C2.

These curves are defined in Annex Q(Q.4.1).

The manufacturer of the pantograph shall provide for the change between the three curves to be made on board taking the appropriate information e.g. use of 1 950 mm pantograph or information on the type of voltage on the overhead contact line. The register of infrastructure defined in Annex D to this TSI of existing lines shall indicate which curve shall be taken into account, i.e. the target curve or the alternative curves C1 or C2.

In case of trains with multiply pantographs simultaneously in operation, the contact force Fm for any pantograph shall not be higher than the value given by the target curve of point 5.3.1.6 or one of the curves C1 or C2 since for each individual pantograph the current collection criteria shall be met.

Those requirements are specified in Annex Q.

Assessment shall be carried out according Annex Q.

5.3.2.8. Automatic dropping device

Pantographs shall be equipped with a device that drops the pantograph in case of a failure according to EN 50206-1, version 1998, point 4.9.

5.3.2.9. Current at standstill

The current drawn by the trains at standstill shall be acceptable for both the contact wire and pantograph collector strips to allow proper feeding of the auxiliaries installed on board trains. For DC systems, in order to be in accordance with point 5.3.1.8, a current of 300 A per pantograph shall be guaranteed. A study shall prove that the pantograph is able to carry the specified current at standstill.

For conformity assessment reference is made to EN 50206-1, version 1998, point 6.13 and Annex Q.

5.3.3. Contact strips

5.3.3.1. Basic parameters

The contact strips of the pantographs shall comply with the basic parameters as given in section 4.1.

5.3.3.2. Materials

The material used for the pantograph contact strips shall be physically and electrically compatible with the contact wire material to avoid abrading the surface of the contact wires excessively, in order to keep wear of both wires and contact strips to a minimum. Plain carbon or carbon impregnated with additive material are accepted for use in interaction with contact wires made from copper or copper alloys. Therefore, this combination should preferably be used for the trans-European high-speed rail system.

Other material may be used in case of DC systems when multilaterally agreed upon. In this case the contact strips cannot be considered as interoperable. Reference is made to Annex M(M.2) to this TSI.

5.3.3.3. Current capacity

The material and cross-section of contact strips shall be selected in the light of the maximum current the contact strip is designed for. The rated current shall be noted on it by the manufacturer. Type tests shall demonstrate the conformity as specified in Annex M(M.4) to this TSI.

5.3.3.4. Current at standstill

An acceptable level of current at standstill shall be acceptable for both the contact wire and pantograph collector strips to allow for the proper supply of auxiliaries installed on-board trains. For DC systems, in order to be in accordance with point 5.3.1.8, a current of 300 A shall be guaranteed per pantograph. A study shall be carried out to prove the capacity of the collector strips. For conformity assessment reference is made to Annex M(M.3) to this TSI.

5.3.3.5. Detection of contact strip breakage

The contact strip shall be designed so that any failures of the contact strips will be detected and the lowering of the pantograph will be triggered. Reference is made to EN 50206-1, version 1998, point 4.9.

6. ASSESSMENT OF CONFORMITY AND/OR SUITABILITY FOR USE

6.1. Interoperability constituents

6.1.1. Assessment procedures and modules

The assessment procedure for conformity of interoperability constituents as defined in Chapter 5 of this TSI shall be carried out by application of modules as specified in Annex A to this TSI.

If the adjudicating entity can demonstrate that tests or verification for previous applications remain valid for the new applications, then the notified body shall take them into account in the conformity assessment.

Assessment procedures for conformity of the interoperability constituents: overhead contact line, pantograph and contact strip as defined in Chapter 5 of this TSI, are indicated in Annex B, Tables B.1 to B.3 to this TSI.

As far as required by the modules specified in Annex A to this TSI, the assessment of conformity of an interoperability constituent shall be appraised by the notified body, when indicated in the procedure, with which the manufacturer or his authorised representative established within the Community has lodged the application.

The manufacturer of an interoperability constituent or his authorised representative established within the Community shall draw up an EC declaration of conformity in accordance with Article 13(1) of and Annex IV, Chapter 3 to Directive 96/48/EC before placing the interoperability constituent on the market. An EC declaration of suitability for use is not required for interoperability constituents of the energy subsystem.

6.1.2. Application of modules

For the assessment procedure of each interoperability constituent of the energy subsystem the manufacturer or his authorised representative established within the Community may choose either:

- the type-examination procedure (module B) indicated in Annex A(A.2) to this TSI for the design and development phase in combination with the conformity to type procedure (module C) indicated in Annex A(A.3) to this TSI for the production phase, or

- the full quality assurance with design examination procedure (module H2) indicated in Annex A(A.4) to this TSI for all phases.

These assessment procedures are defined in Annex A to this TSI.

The module H2 may only be chosen where the manufacturer operates a quality system for design, production, final product inspection and testing, approved and surveyed by a notified body.

The conformity assessment shall cover the phases and characteristics as indicated by X in the Tables B.1, B.2 and B.3 of Annex B to this TSI.

6.2. Energy subsystem.

6.2.1. Assessment procedures and modules

At the request of the adjudicating entity or its authorised representative established within the Community, the notified body carries out the EC verification in accordance with Article 18(1) of and Annex VI to Directive 96/48/EC and in accordance with the provisions of the relevant modules as specified in Annex A to this TSI.

If the adjudicating entity can demonstrate that tests or verification for previous applications remain valid for the new applications, then the notified body shall take them into account in the conformity assessment

Assessment procedures for the EC verification of the energy subsystem are indicated in Annex C, Table C.1, to this TSI.

As far as specified in this TSI the EC verification of the energy subsystem shall take account of its interfaces with other subsystems of the trans-European high-speed rail system.

The adjudicating entity shall draw up the EC declaration of verification for the Energy subsystem in accordance with Article 18(1) of and Annex V to Directive 96/48/EC.

6.2.2. Application of modules

For the verification procedure of the Energy subsystem the adjudicating entity or its authorised representative established within the Community may choose either:

- the unit verification procedure (module SG) indicated in Annex A(A.5) to this TSI, or

- the full quality assurance with design examination procedure (module SH2) indicated in Annex A(A.6) 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 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.

7. IMPLEMENTATION OF THE ENERGY TSI

7.1. Application of this TSI to high-speed lines and rolling stock to put into service

As to the high-speed lines within the geographic scope of this TSI (see section 1.2) and to the rolling stock which will be put into service after the entry into force of this TSI, Chapters 2 to 6 are entirely applicable, as well as possible specific provisions of section 7.3 hereafter.

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

In respect of infrastructure installations and rolling stock already in operation, this TSI applies to components under the conditions specified in Article 3 of this Decision. In this particular context, it relates fundamentally to the application of a migration strategy that enables an economically justifiable adaptation of existing installations to be made taking into account the principle of grandfather rights. The following principles apply in the case of the TSI on energy.

While the TSI can be fully applied to new installations, implementation on existing lines may require modifications of existing installations. The modification necessary will depend on the extent of conformity of the existing installations. An implementation strategy can only be made individually for given lines or networks in the Member States of the Comunity. Section 7.3 indicates those items where implementation needs modification of existing installations. Table 7.1 summarises the characteristics to be implemented.

The contracting entity shall define the practical measures and the different phases which are necessary to allow placing into service with the required performances. These phases may include transition periods for placing into service with reduced performances.

Table 7.1

Implementation of technical specifications for interoperability, energy subsystem

>TABLE>

7.3. Specific cases

The following special provisions are authorised in the following specific cases. These specific cases are classified according to two categories: the provisions apply either permanently ("P" cases), or temporarily ("T" cases). As to temporarily cases, it is recommended that the target system is reached either by 2010 (cases "T1"), an objective set in Decision No 1692/96/EC 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 by 2020 (cases "T2").

7.3.1. Particular features on the Austrian network

Connecting lines

The investment of changing the overhead contact line on upgraded and connecting lines and in stations to meet the requirements of the 1600 mm Euro pantograph is prohibitive. Trains traversing these lines will have to be provided with secondary 1950 mm pantographs for medium-speed operation up to 230 km/h so that the overhead contact line on these parts of the trans-European network will not have to be prepared for the operation of the Euro pantograph. In these areas a maximum lateral deflection of contact wire of 550 mm under action of cross wind is permissible. Future studies concerning upgraded and connecting lines should take into account the Euro pantograph to demonstrate the relevance of the choices made.

Connecting and upgraded lines (P case)

Due to the acceptance of designing the overhead contact line for a 1950 mm wide pantograph there is no need for adjustment.

Connecting lines (T1 case)

To comply with the requirements on mean useful voltage and installed power additional substations are necessary. Installation is planned until 2010.

7.3.2. Particular features on the Belgian network (T1 case)

Existing high-speed lines

On existing high-speed lines the phase separation sections are not compatible with the requirement of pantograph distance between three pantographs of more than 143 m. Between existing high-speed lines and upgraded lines there is no automatic control to trigger the opening of the main circuit breaker on the traction vehicles.

Both items have to be modified.

Connecting and upgraded lines

On some line sections, under bridges, the contact wire height does not meet the TSI minimum requirements and will have to be modified. Dates are open.

7.3.3. Particular features on the German network (P case)

The investment of changing the overhead contact line on upgraded and connecting lines and in stations to meet the requirements of the 1600 mm Euro pantograph is prohibitive. Trains traversing these lines will have to be provided with secondary 1950 mm pantographs for medium-speed operation up to 230 km/h so that the overhead contact line on these parts of the trans-European network will not have to be prepared for the operation of the Euro pantograph. In these areas a maximum lateral deflection of contact wire of 550 mm under action of crosswind is permissible. Future studies concerning upgraded and connecting lines should take into account the Euro pantograph to demonstrate the relevance of the choices made.

7.3.4. Particular features on the Spanish network (P case)

The investment of changing the overhead contact line on upgraded and connecting lines and in stations to meet the requirements of the 1600 mm Euro pantograph is prohibitive. Trains traversing these lines will have to be provided with secondary 1950 mm pantographs for medium-speed operation up to 230 km/h so that the overhead contact line on these parts of the trans-European network will not have to be prepared for the operation of the Euro pantograph. In these areas a maximum lateral deflection of contact wire of 550 mm under action of crosswind is permissible. Future studies concerning upgraded and connecting lines should take into account the Euro pantograph to demonstrate the relevance of the choices made.

The nominal contact wire height can be 5,50 m on some sections of future high-speed lines in Spain; particularly in case of the future high-speed line between Barcelona and Perpignan. (It would concern also France between the Spanish border and Perpignan if this country asked for it.)

For the high-speed line Madrid-Seville, trains have to be equipped with a 1950 mm pantograph.

7.3.5. Particular features on the French network

Existing high-speed lines (T2 case)

To provide for the criteria of current collection and dynamic behaviour on AC lines modification of overhead line equipment is necessary.

On existing high-speed lines the phase separation sections are not compatible with the pantograph arrangement between three pantographs of more than 143 m. Phase separation sections have to be modified.

On a specific high-speed line a modification of the overhead contact line is necessary to provide for the permissible uplift without uplift stops installed in the pantographs.

Upgraded and connecting lines

To provide for the criteria of current collection on DC lines modification of overhead line equipment is necessary. For DC lines the cross-section of contact wires is not sufficient to comply with the TSI requirements for current at standstill in stations or in areas where trains are pre-heated.

The existing DC line to Spain is operated with a 1950 mm DC collector head. To operate this line with interoperable 1600 mm Euro collector heads the overhead line has to be upgraded accordingly.

All categories of lines

The following applies for the pantographs:

- for AC systems a 1600 mm Euro collector head is needed instead of 1450 mm pan heads currently in use on TGVs,

- for DC systems a 1600 mm Euro collector head is needed instead of 1950 mm wide pan heads currently used on TGVs,

- for AC systems during an intermediate period, use of pantographs capable of operating with three targets curves (C1, C2 and target curve) for the mean contact force Fm is necessary,

- for DC systems the use of pantographs capable of operating with two Fm curves, one for 1,5 kV and another for 3 kV might be necessary.

The conversion has not yet been scheduled.

7.3.6. Particular features on the British network

New high-speed lines (T1 case)

On the planned Channel Tunnel railway line (CTRL) the phase separation sections may need adjusting to the specifications in the TSI. This amendment will be carried out with the introduction of full-service including freight trains.

Upgraded lines (P case)

On the east coast main line (ECML) some sections do not comply with the specifications for voltage and frequency, mean useful voltage and installed power. Implementation of the TSI is planned with the next major upgrade for the ECML.

On the ECML and the west coast main line (WCML) the geometry of overhead contact line and dynamic envelope are based on UK1 gauge and are treated as a special case. The variable contact wire height may be retained for speeds up to 225 km/h and the mean contact force will be adjusted to achieve the current collection requirements of EN 50119, version 2001, point 5.2.1.

On the WCLM the existing type of phase separation sections will be retained.

7.3.7. Particular features on the Italian network

Existing high-speed lines (T1 case)

Geometry of overhead contact lines needs to be adjusted for height of contact wire on a length of 100 km double track line.

These modifications will be carried out until 2010.

Connecting and upgraded lines (T1 case)

Geometry of overhead contact lines needs to be adjusted concerning height of contact wire on parts of lines involved.

To comply with the requirements on mean useful voltage and installed power additional substations are necessary.

These modifications will be carried out until 2010.

7.3.8. Particular features on the Irish and Northern Irish networks (P cases)

On electrified lines of the Irish and Northern Irish networks, the IRL1 Irish standard structure gauge and the necessary clearances will define the nominal contact wire height.

7.3.9. Particular features on the Swedish network (P case)

The investment of changing the overhead contact line on upgraded and connecting lines and in stations to meet the requirements of the 1600 mm Euro pantograph is prohibitive. Trains traversing these lines will have to be provided with secondary 1950 mm pantographs for medium-speed operation up to 230 km/h so that the overhead contact line on these parts of the trans-European network will not have to be prepared for the operation of the Euro pantograph. In these areas a maximum lateral deflection of contact wire of 550 mm under action of crosswind is permissible. Future studies concerning upgraded and connecting lines should take into account the Euro pantograph to demonstrate the relevance of the choices made.

7.3.10. Particular features on the Finnish network (P case)

The normal height of the contact wire is 6150 mm (minimum 5600 mm, maximum 6500 mm).

A.1. SCOPE

This annex covers the modules for the assessment procedures for the Conformity assessment of Interoperability Constituents and the EC verification of the Energy subsystem.

A.2. MODULE B (TYPE-EXAMINATION)

Conformity assessment of interoperability constituents

1. This module describes that part of the procedure by which a notified body ascertains and attests that a type, representative of the production envisaged, meets the provisions of the TSI that apply to it.

2. The application for the type-examination must be lodged by the manufacturer or his authorised representative established within the Community with a notified body of his choice.

The application must include:

- the name and address of the manufacturer and, if the application is lodged by the authorised representative, his name and address in addition,

- a written declaration that the same application has not been lodged with any other notified body,

- the technical documentation, as described in point 3.

The applicant must place at the disposal of the notified body a specimen, representative of the production envisaged, and hereinafter called "type".

A type may cover several versions of the interoperability constituent provided that the differences between the versions do not affect the provisions of the TSI.

The notified body may request further specimens if needed for carrying out the test programme.

If no type tests are requested within the type-examination procedure (see point 4.4), and the type is sufficiently defined by the technical documentation, as described in point 3, the notified body may agree, that no specimens are placed at their disposal.

3. The technical documentation must enable the conformity of the interoperability constituent with the provisions of the TSI to be assessed. It must, as far as relevant for such assessment, cover the design, manufacture and operation of the product.

The technical documentation must contain:

- a general type-description,

- conceptual design and manufacturing drawings and schemes of components, sub-assemblies, circuits, etc.,

- descriptions and explanations necessary for the understanding of said drawings and schemes and the operation of the product,

- conditions of integration of the interoperability constituent in its system environment (sub-assembly, assembly, subsystem) and the necessary interface conditions,

5. Where the type meets the provisions of the TSI, the notified body must issue a type-examination certificate to the applicant. The certificate must contain the name and address of the manufacturer, conclusions of the examination, conditions for its validity and the necessary data for identification of the approved type.

The time period of validity shall be no longer than three years.

A list of the relevant parts of the technical documentation must be annexed to the certificate and a copy kept by the notified body.

If the manufacturer or his authorised representative established within the Community is denied an EC type-examination certificate, the notified body must provide detailed reasons for such denial.

Provision must be made for an appeals procedure.

6. The applicant must inform the notified body that holds the technical documentation concerning the EC type-examination certificate of all modifications to the approved product which must receive additional approval where such changes may affect the conformity with the requirements of the TSI or the prescribed conditions for use of the product. This additional approval is given in the form of an addition to the original type-examination certificate, or a new certificate will be issued after withdrawal of the old certificate.

7. If no modifications as under point 6 have been made, the validity of an expiring certificate can be extended for another period of validity. The applicant will apply for such a prolongation by a written confirmation that no such modifications have been made, and the notified body issues a prolongation for another period of validity as in point 5, if no contrary information exists. This procedure can be reiterated.

8. Each notified body must communicate to the other notified bodies the relevant information concerning the type-examination certificates it has withdrawn or refused.

9. The other notified bodies will receive copies of the type-examination certificates issued and/or their additions on request. The annexes to the certificates must be kept at the disposal of the other notified bodies.

10. The manufacturer or his authorised representative established within the Community must keep with the technical documentation copies of the EC type-examination certificates and their additions for a period of 10 years after the last product has been manufactured Where neither the manufacturer nor his authorised representative is established within the Community, the obligation to keep the technical documentation available is the responsibility of the person who places the product on the Community market.

A.3. MODULE C (CONFORMITY TO TYPE)

Conformity assessment of interoperability constituents

1. This module describes that part of the procedure whereby the manufacturer or his authorised representative established within the Community ensures and declares that the interoperability constituent concerned is in conformity with the type as described in the EC type-examination certificate and satisfies the requirements of Direct
