(3) Requirements in this TSI are valid for all track gauge systems within the scope of this TSI, unless a paragraph refers to specific track gauge systems or to specific nominal track gauges.

2. DESCRIPTION OF THE ENERGY SUBSYSTEM

2.1.   Definition

(1) This TSI covers all fixed installations necessary to achieve interoperability that are required to supply traction energy to a train.

(2) The energy subsystem consists of: (a) substations : connected on the primary side to the high-voltage grid, with transformation of the high-voltage to a voltage and/or conversion to a traction power supply system suitable for the trains. On the secondary side, substations are connected to the railway contact line system; (b) sectioning locations : electrical equipment located at intermediate locations between substations to supply and parallel contact lines and to provide protection, isolation and auxiliary supplies; (c) separation sections : equipment required to provide the transition between electrically different systems or between different phases of the same electrical system; (d) contact line system : a system that distributes the electrical energy to the trains running on the route and transmits it to the trains by means of current collectors. The contact line system is also equipped with manually or remotely controlled disconnectors which are required to isolate sections or groups of the contact line system according to operational necessity. Feeder lines are also part of the contact line system; (e) return circuit : all conductors which form the intended path for the traction return current. 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.

(3) In accordance with Annex II, Section 2.2 of  Directive (EU) 2016/797, the trackside of the electricity consumption measuring system, referred to in this TSI as on-ground energy data collecting system, is set out in point 4.2.17 of this TSI.

(1)The objective of the traction power supply system is to supply every train with power in order to meet the planned timetable.

(2)Basic parameters for traction power supply system are set out in point 4.2.

(1) The objective is to ensure reliable and continuous power transfer from the traction power supply system to the rolling stock. The interaction between the overhead contact line and the pantograph is an important aspect of interoperability.

(2) Basic parameters referring to the geometry of the OCL and quality of current collection are set out in point 4.2.

2.2.   Interfaces with other subsystems

(1) The energy subsystem interfaces with other subsystems of the rail system in order to achieve the envisaged performance. These subsystems are listed below: (a) Rolling stock; (b) Infrastructure; (c) Trackside control command and signalling; (d) On-board control command and signalling; (e) Operation and traffic management.

(2) Point 4.3 of this TSI sets out the functional and technical specification of these interfaces.

Requirements relating to the energy subsystem for safety in railway tunnels are set out in the TSI relating to Safety in railway tunnels.

3. ESSENTIAL REQUIREMENTS

The following table indicates basic parameters of this TSI and their correspondence to the essential requirements as set out and numbered in Annex III of  Directive (EU) 2016/797.

4. CHARACTERISATION OF THE SUBSYSTEM

4.1.   Introduction

(1) The whole rail system, to which  Directive (EU) 2016/797 applies and of which the energy subsystem is a part, is an integrated system whose consistency needs to be verified. This consistency must be checked, in particular, with regard to the specifications of the energy 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 points 4.2 and 4.3, do not impose the use of specific technologies or technical solutions, except where this is strictly necessary for the interoperability of the rail network.

(2) Innovative solutions for interoperability, which do not fulfil requirements specified in this TSI and are not assessable as stated in this TSI, 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 for innovative solutions described in points 6.1.3 and 6.2.3.

(3) Taking account of all the applicable essential requirements, the energy subsystem is characterised by the specifications set out in points 4.2 to 4.7.

(4) Procedures for the EC verification of the energy subsystem are indicated in point 6.2.4 and Appendix B, Table B.1, of this TSI.

(5) For specific cases, see point 7.4.

(6) Where reference is made to EN standards in this TSI, any variations called ‘national deviations’ or ‘special national conditions’ in the EN standards are not applicable and do not form part of this TSI.
