Railway applications - Compatibility between rolling stock and train detection systems - Part 2: Compatibility with track circuits
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.

1 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.

4 General aspects of interference current limits for RST
4.1 Derivation of interference current limits for RST
The interference limits are defined for a set of preferred types of existing track circuits which are also defined
1)
by Railway Infrastructure companies for use on future new signalling projects on interoperable lines . If it is
found that the line over which the rolling stock is intended to run is equipped with an older version or with
non-preferred track circuit then National Notified Technical Rules shall be used. It is not the intention of this
Technical Specification to mandate any particular type of train detection but it is expected that because the
list of preferred types and their limits for compatibility are drawn on the basis of established performance
criteria, the trend will be that upgraded interoperable lines are fitted with types which meet the compatibility
limits published in this Technical Specification. The complete set of compatibility requirements for existing
preferred and future types of track circuits to be installed on interoperable lines is outside the scope of this
Technical Specification.
In principle, the preferred types of track circuits from CLC/TR 50507 have been considered in defining the
interference current limits for RST. Where new upgrades of track circuits are available, their improved
susceptibility limits have been taken into account in this Technical Specification. These upgraded track
circuits whose limits are incorporated in the interference current limits for RST are marked with a star in the
lists of track circuits provided in Clause 6.
Annex A defines the interference current limits for compatibility with track circuits. The interference current
limits for RST are defined up to and including the highest frequency range occupied by existing track circuits.
The limits are defined under worst case credible failure conditions of the track circuit such as unbalance or
broken bonds or rails as defined by national authorities.
4.2 Application of Interference current limits to RST design
The interference current limits for RST and associated test methods apply to one influencing unit.
By definition, the interference current limits for RST are based on the maximum steady state interference
signal to which the track circuit may be exposed.
The rolling stock interference current limits for RST incorporate the established margins for the relevant track
circuits which take into account for interference current already generated by other vehicles on adjacent
tracks. Specific traction supply harmonics circulated through the impedance of the influencing unit are dealt
with as part of the evaluation methods.
1)
The interference current limits and the measurement specification defined in this standard apply to rolling stock intended to run over
interoperable lines equipped with preferred types of track circuits as defined by national infrastructure authorities.
---------------------- Page: 12 ----------------------
SIST-TS CLC/TS 50238-2:2010
- 11 - CLC/TS 50238-2:2010
In the case of testing of single traction units on the operational railway the interference current limits for RST
will have to be applied to the influencing unit by using applicable summation rules. See also Clause 7 and
8.1.
The interference current limits for RST are defined at absolute frequencies and therefore not dependent on
mains variations.
A vehicle is required to conform only to the interference current limits for RST for the traction system(s) (DC,
16,7 Hz, 50 Hz) on which it is intended to operate.
