European foreword
This document (CLC/TS 50238-2:2020) has been prepared by CLC/SC 9XA “Communication, signalling and
processing systems” of Technical Committee CLC/TC 9X, “Electrical and electronic applications for
railways”.
This document supersedes CLC/TS 50238-2:2015 and its corrigendum of July 2016.
CLC/TS 50238-2:2015:
The interference current limits for RST have been updated in the normative Annex A.
This Technical Specification is Part 2 of the EN 50238 series published under the title Railway
applications — Compatibility between rolling stock and train detection systems. The series consists of:
— Part 1: General:
— Part 2: Compatibility with track circuits [this document];
— Part 3: Compatibility with axle counters.
Introduction
This Technical Specification defines the interference limits and evaluation criteria for electromagnetic
compatibility between rolling stock and track circuits.
The limits have been defined on the basis of national specifications described in NTRs.
This Part 2 of the series defines:
— a set of interference current limits for rolling stock based on defined track circuits,
— measurement and evaluation methods to verify rolling stock interference current emissions and
demonstrate compatibility with the track circuits;
— traceability of compatibility requirements (types of track circuit and associated limits).
1 Scope
This document defines, for the purpose of ensuring compatibility between rolling stock and track circuits, the
limits for interference current emissions from rolling stock. The measurement and evaluation methods for
verifying conformity of rolling stock to these limits are presented in a dedicated annex.
The interference limits are only applicable to rolling stock that is intended to run on lines exclusively
equipped with preferred track circuits listed in this document. The rolling stock test methodology
(infrastructure conditions, test configurations, operational conditions, etc.) presented in this document is
applicable to establish compatibility with any track circuits.
This document gives guidance on the derivation of interference current limits specified for rolling stock and
defines measurement methods and evaluation criteria in a dedicated annex.
This document defines:
a) a set of interference current limits for RST (Rolling Stock) applicable for each of the following types of
traction system:
1) DC (750 V, 1,5 kV and 3 kV);
2) 16,7 Hz AC;
3) 50 Hz AC;
b) methodology for the demonstration of compatibility between rolling stock and track circuits;
c) 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 document.
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 document.
