Railway Applications - Fixed installations and rolling stock - Technical criteria for the coordination between electric traction power supply systems and rolling stock to achieve interoperability - Part 1: General

This document establishes requirements for the electrical aspects to achieve technical compatibility between rolling stock and electric traction systems, limited to:*- co-ordination of protection principles between power supply and traction units, i.e. separation sections, train set current or power limitation, short circuit current discrimination, breaker coordination and use of regenerative braking.*- co-ordination of installed power on the line and the power demand of trains, i.e. traction unit power factor, train set current or power limitation, electric system performance, type and characterization.*- compatibility assessment relating to harmonics and dynamic effects.*Informative values are given for some parts of the existing European railway networks, in annexes.*NOTE – For those railways within the scope of EU Interoperability Directive, definitive values are set out in the register of infrastructure published in accordance with Article 49 of Directive (EU) 2016/797, and the list of items included in the register is described in the commission decision (EU) 2019/777.*The following electric traction systems are within the scope of this document:*- railways;*- guided mass transport systems that are integrated with railways;*- material transport systems that are integrated with railways.*Information is given on electrification parameters to enable train operating companies to confirm, after consultation with the rolling stock manufacturers, that risks of non-compatibility are minimized and that there will be no consequential disturbance on the electrification system.*The interaction between pantograph and overhead contact line is dealt with in EN 50367:2020.*The interaction with the control-command and signalling subsystem is not dealt with in this document.*Basic considerations have been included concerning the use of accumulator trains.
