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

4 General requirements
4.1 Functional description
Shore (external) supply systems have the following main functions:
— feed the auxiliary electrical equipment on board railway vehicles from an external power source;
— ensure safety during operation of shore (external) supply systems and rolling stock;
— ensure that the connecting and disconnecting operations take place under conditions of zero current;
— ensure that movement of the rolling stock is not possible when the shore (external) power supply is
physically connected. This requirement is not applicable for hauled trains.
The phase order shall be 1, 2, 3 using the contacts as set out in 6.1.3.
4.2 System requirements
4.2.1 General
4.2.1.1 Rolling stock side of the system
The rolling stock side of the system consists of the fixed connector and the associated controls and protection
devices.
The functional requirements of the rolling stock are set out in EN 50533:2011, Clause 5.
4.2.1.2 Shore side (Infrastructure) of the system
The shore side of the system consists of the free connector, connector stowage location, cable and power
supply with its associated control and protection devices.
The voltage requirements of the shore (external) supply system are set out in EN 50160.
4.2.2 Supply voltages for the shore supply system
Supply voltage range is:
3-phase AC + N; 400 V, 50 Hz voltage range ± 10 %
Full characteristics of the shore supply are set out in EN 50533:2011, Clause 5, and EN 50160.
NOTE EN 50533:2011, Clause 5 states that the supply is 3 phase AC floating. This means that the Neutral is floating
and so not connected to the earth.
The phases assigned to the contacts in the connectors shall be as set out in Annex A for the 63 A/125 A
connectors and Annex B for the 600 A connectors.
For DC railways, the earthing arrangements as set out in the EN 50122-1:2011 shall be considered.
For AC traction: The installer of the shore side (infrastructure) system shall connect any earths provided on
the free connector to the earth of the shore side (infrastructure) system.
For DC traction: Depending on the earth principle of the DC traction installation and the train signalling the
installer of the shore side (infrastructure) system shall decide how to connect any earths provided on the free
connector to the earth of the shore side (infrastructure) system.
4.2.3 Power limitation
4.2.3.1 Current ratings for the shore supply system
The maximum external supply power for one infeed point shall be limited to the values specified in Table 1.
NOTE The pilot and control contacts are not rated for these currents.
The breaking capacity of the pilot contacts shall be 110 V DC, 2 A minimum.
Table 1 — Shore supply power ratings
Type of socket Rated operating current Remarks
(continuous load at an ambient
temperature of 20 °C)
3-phase AC; 400 V, 50 Hz 600 A per phase 400 kW High power system
3-phase AC + N; 400 V, 50 Hz 125 A per phase 86 kW Medium power system
3-phase AC + N; 400 V, 50H z 63 A per phase 44 kW Low power system
4.2.3.2 Current restriction on the rolling stock system
For the 63 A/125 A connector, the rolling stock shall be able to read the shore supply rated operating current
through the coding contacts, as set out in 6.8.2.2, and control the onboard systems such that only 63 A is
drawn, without damage to the onboard equipment, when only 63 A is available from the shore side
(infrastructure) system.
NOTE This could be done by including a load shed mode for the shore (external) supply system.
For the 600 A connector current restriction is done by the overload protection on the shore side (infrastructure)
by disconnection. No disconnection due to overload has to be ensured by operational routines.
4.2.4 Emergency cut-off switch
All shore (external) supply systems shall be equipped with a clearly visible and readily identifiable emergency
cut-off switch to disconnect the power supply. This emergency cut-off switch shall be coloured red. Once
activated, it is recommended that the emergency cut-off switch requires a key to deactivate the emergency
cut-off and reset the system.
The emergency cut-off switch shall be part of the shore side (infrastructure) system.
4.2.5 Earth fault system
An on-board earth fault system shall be provided to ensure that:
— when an earth fault is detected on the rolling stock, the system prevents energization of the shore supply
by using the pilot contacts;
— if energized the shore supply system shall operate the protection on detection of an earth fault on the
rolling stock.
NOTE An earth fault can be detected in some cases due to leakage currents caused by EMC filters. Therefore, an
adaptive residual current circuit breaker or a short-time suppression of the earth fault detection can be used to avoid this
operational condition.
4.2.6 Prevention of-Energization of fixed connector by the vehicle
The fixed connector mounted on the vehicle shall not be energized from the onboard auxiliary electrical
supply.
The coding contact circuit for the 63 A /125 A fixed connector shall only be energised when the pilot contacts
are proved connected.
4.2.7 Shore side (infrastructure) system
4.2.7.1 Energization conditions
Electrical parts of the free (infrastructure) connector shall be de-energized when the shore (external) supply
system is not in use.
The shore side system shall include a visible indication, which indicates that the system is live.
NOTE The indication does not have to be on the connector.
4.2.7.2 Stowage of connector
It is recommended that the shore side (infrastructure) system shall include a stowage location for the free
connector when not in use. It is recommended that there is both mechanical and electrical connection at the
stowage location. It is recommended that the stowage system shall provide an indicator that shows:
— that the shore supply system is connected and supplies power to the rolling stock;
— that the free connector is not stowed;
— that the free connector is safely stowed.
The indicator that shows that the shore supply system is connected and supplies power to the rolling stock
may be the one that shows that the shore supply system is live. The stowage device should be located such
that the indicator is visible from the rolling stock connector location and the length of cable is minimized.
It is recommended that the stowage device is mounted at an angle to match the connection to the fixed
connector and reduce the risk of water ingress.
4.2.8 Overload protection
Overload protection shall be provided on the shore (external) power supply that considers the inrush current
and starting characteristics of the railway vehicle auxiliary loads, particularly on high power auxiliary systems.
4.2.9 Traction and brake interlock
The train shall include interlocking to ensure that movement of the rolling stock is not possible when the shore
(external) power supply is connected.
4.2.10 Cables
The cables used shall meet the requirements set out in EN 50264-3-1:2008 for cables not only for rolling stock
but also for shore side (infrastructure) systems (connection between supply unit and rolling stock).
This provides performance compatibility and interoperability for the connectors.
NOTE The connectors are dimensioned based on the sizes of the standard railway cables.
4.3 Installation — Mounting of fixed connector
Where the fixed connector is mounted in location 4 as set out in EN 50467:2011, the connector shall be
mounted at an angle to prevent water ingress.
It is recommended that the shore supply connector is accessible from track level to allow for interoperability
with the shore side (infrastructure) system. The shore side (infrastructure) supply is commonly located on a
short post at track level or at the platform level.
5 Classification
5.1 General
The shore supply connector shall comply with EN 50467:2011 unless otherwise specified in this document.
5.2 Intended use of rolling stock
The shore supply connectors can be used on different rolling stock types for example tramways, light rail and
metro systems, commuter trains, regional trains and high-speed trains as well as locomotive hauled
passenger and freight trains.
5.3 Location of connector on-board rolling stock
The permitted installation locations for rolling stock connectors are limited to Locations 1 to 4 as set out in
EN 50467:2011, Figure 3.
NOTE 1 These connectors are not fitted in dynamic locations as they are only used when the rolling stock is static.
NOTE 2 All requirements have been specified for the most severe environment.
