This standard BS EN 50546:2024 Railway applications. Rolling Stock. Three-phase shore (external) supply system for rail vehicles and its connectors is classified in these ICS categories:
45.060.01 Railway rolling stock in general
29.120.30 Plugs, socket-outlets, couplers
29.280 Electric traction equipment
The shore supply system is used while the rolling stock is standing still within depots and sidings location for providing power to the AC auxiliary loads (which can include battery charging) when the primary power supply (contact line) is not available or used. This document: - specifies requirements to the shore supply and to the rolling stock for safe operation on shore supply operation; - specifies the requirements to ensure compatibility of class C0 and C1 train types as given in CLC/TS 50534:2010 systems and three-phase shore power supply systems; - provides a complete system design for 63/125 A shore supplies including the interfaces (power and control loop) between shore supply and rolling stock; - specifies the requirements with regards to interoperability with AC and DC fed traction systems in order to prevent undesired stray currents and adverse interaction with signalling systems when operating on shore supply; - defines the electrical characteristics of the 63/125 A shore power supply; - defines the 63/125 A connectors and its intermateability to provide interoperability for rolling stock that is to run across borders; - defines the 600 A connector and its intermateability; - can be used for other type of rail vehicles and purposes, if agreed by the manufacturer and customer - does not apply to shore supplies to move the rolling stock; - does not describe the 600 A shore supply system. NOTE 1 The 600 A connector is the existing UK standard three-phase shore supply connector which has a long service history. NOTE 2 The connectors are dimensioned using standard rolling stock cables as set out in EN 50264-3-1:2008. NOTE 3 Examples of other usage and rail vehicles are: e.g. light rail vehicles, class A train types, traction battery charging etcetera.
