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



Reference CLC/TS 50238-3:2010
Title Railway applications - Compatibility between rolling stock and train detection systems - Part 3: Compatibility with axle counters
Project Number 21550
Abstract/Scope This Technical Specification defines, for the purpose of ensuring compatibility between rolling stock and track circuits the limits for conducted interference from rolling stock and the measurement method for verifying conformity of rolling stock to these limits. The interference limits are only applicable to interoperable rolling stock which is intended to run on lines exclusively equipped with preferred track circuit listed in this Technical Specification. National Notified Technical Rules are still to be used in all cases, where the line over which the rolling stock is intended to run is equipped with any type of older version or non-preferred track circuits that are not listed in this Technical Specification. However, the rolling stock test methodology (infrastructure conditions, test configurations, operational conditions, etc.) presented in this Technical Specification is also applicable to establish compatibility with non-preferred track circuits. This Technical Specification gives guidance on the derivation of interference current limits specified for rolling stock and defines measurement methods and evaluation criteria. This Technical Specification defines • a set of interference current limits for RST (Rolling Stock) applicable for each of the following types of traction system: - DC (750 V, 1,5 kV and 3 kV); - 16,7 Hz AC; - 50 Hz AC. • methodology for the demonstration of compatibility between rolling stock and track circuits, • measurement method to verify interference current limits and evaluation criteria. NOTE 1  The basic parameters of track circuits associated with the interference current limits for RST are not in the scope of this Technical Specification. NOTE 2  Any phenomena linked to traction power supply and associated protection (over voltage, short-circuit current, under- and over-voltage if regenerative brakes are used) is part of the track circuit design and outside the scope of this Technical Specification.

(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
