E DIN EN 50546 VDE 0115-546:2023-12

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 systems and three-phase shore power supply systems;
— provides a complete system design for 63 A/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 shore power supply;
— defines intermateable connectors for the 63 A/125 A and 600 A systems to provide interoperability for rolling stock that is to run across borders;
— 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 600A shore supply system.
