Introduction
The shore supply system is used within depots and sidings location for providing power to the auxiliary
electrical supply (which may include battery charging) when the primary power supply is not available, and the
train is static (0 km/h). This document defines connectors that are intermateable to provide interoperability for
rolling stock that is to run across borders and has been equipped with batteries which are be charged in
locations other than their normal depot or sidings location.
The connectors are dimensioned using standard rolling stock cables as set out in EN 50264-3-1:2008.
This document provides the requirements for compatibility of systems defined and good practice 3-phase
AC + N; 400 V, 50 Hz shore (external) supply systems. It focuses on describing the defined interfaces
regarding electrical power supply in stations, depots/workshops and sidings location into the rail vehicle.
This document provides recommended characteristics of power supply and the interface drawings for the
shore supply connectors. The interface drawings are supplied to provide intermateability and interoperability of
connectors. The fixed connector is provided with a protective cover to prevent any ingress when the connector
is not in use.
Two connectors have been specified in this document. The first is suitable for either 63 A or 125 A shore
supplies. The second is suitable for 600 A shore supplies. The 600 A connector is the existing UK standard
three-phase shore supply connector which has a long service history.

1 Scope
This document specifies requirements for the shore supply system for auxiliaries and pre-conditioning and the
related intermateable connector pairs. This standard specifies the characteristics of the connectors in order to
achieve interoperability at the rolling-stock/shore power supply interface.
This document does not apply to shore supplies to move the rolling stock.

276 Introduction
277 This standardization project was derived from the EU-funded Research project MODTRAIN (MODPOWER). It
278 is part of a series of standards, referring to each other. The hierarchy of the standards is intended to be as set
279 out in Figure 1:
CLC/TS 50534
Generic system architectures for onboard electric auxiliary
power systems
 Level 1: Architecture
CLC/TS 50535 EN 50533 EN 50546
Onboard auxiliary power converter Three-phase train line voltage Shore (external) supply systems for rail
systems characteristics vehicles
 Level 2:Systems, Interfaces

Batteries for rail vehicles HV bushing for traction transformers

CLC/TS 50537-4

Water Pump for traction converters for liquid immersed transformers and
reactors with conservator for rail vehicles
 Level 3: Components
280
281 Figure 1 — Overview on the technical framework CLC/TS 50534 defines the basis for other dependent
282 standards
283 The shore supply system is used within depots and sidings for providing power to the auxiliary electrical
284 supply (which may include battery charging) when the primary power supply is not available, and the train is
285 static (0 km/h). This document defines connectors that are intermateable to provide interoperability for rolling
286 stock to run across borders and be charged in locations other than their normal depot or sidings location.
287 The connectors are dimensioned using standard rolling stock cables as set out in EN 50264-3-1.
288 This document provides the requirements for compatibility of systems defined and good practice for three
289 phase + Neutral AC 400 V/50 Hz shore (external) supply systems. It focuses on describing the defined
290 interfaces regarding electrical power supply in stations, depots/workshops and stabling points into the rail
291 vehicle.
292 This document provides recommended characteristics of power supply and the interface drawings for the
293 shore supply connectors. The interface drawings are supplied to provide intermateability and interoperability of
294 connectors. The fixed connector is provided with a protective cover to prevent any ingress when the connector
295 is not in use.
296 Two connectors have been specified in this document. The first is suitable for either 63 A or 125 A shore
297 supplies. The second is suitable for 600 A shore supplies. The 600 A connector is the existing UK standard
298 three-phase shore supply connector which has a long service history.
299 The contacts in the connector have each been assigned a phase.
