International Standards and Conformity Assessment for all electrical, electronic and related technologies


Electric supply and earthing systems for public transport equipment and ancillary apparatus (Fixed installations)



Reference EN 50388:2012/AC:2012
Title Railway Applications - Power supply and rolling stock - Technical criteria for the coordination between power supply (substation) and rolling stock to achieve interoperability
Project Number 24414
Abstract/Scope This European Standard establishes requirements for the compatibility of rolling stock with infrastructure particularly in relation to: – co-ordination of protection principles between power supply and traction units, especially fault discrimination for short-circuits; – co-ordination of installed power on the line and the power demand of trains; – co-ordination of traction unit regenerative braking and power supply receptivity; – co-ordination of harmonic behaviour. This European Standard deals with the definition and quality requirements of the power supply at the interface between traction units and fixed installations. This European Standard specifies the interface between rolling stock and electrical fixed installations for traction, in respect of the power supply system. The interaction between pantograph and overhead contact line is dealt with in EN 50367. The interaction with the “control-command” subsystem (especially signalling) is not dealt with in this standard. Requirements are given for TSI lines (both high speed and conventional) and classical lines. For classical lines, values, where given, are for the existing European networks. Furthermore the maximum values that are specified are applicable to the foreseen developments of the infrastructure of the Trans European rail networks. The following electric traction systems are within scope: – railways; – guided mass transport systems that are integrated with railways; – material transport systems that are integrated with railways. This European Standard does not apply retrospectively to rolling stock already in service. Information is given on electrification parameters such as to enable train operating companies to confirm, after consultation with the rolling stock manufacturers, that there will be no consequential disturbance on the electrification system.

Normative reference (6)  

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
