Railway applications - Compatibility between rolling stock and train detection systems - Part 3: Compatibility with axle counters

For the purpose of demonstrating compatibility between rolling stock and axle counter detectors, this Technical Specification defines the interference limits and evaluation methods to verify rolling stock emissions. Wheel sensors and crossing loops are not covered by this Technical Specification. This Technical Specification gives recommended individual limits to be applied to establish compatibility between RST and all selected types of axle counter detectors, including any covered by national standards. The list of selected types of axle counters and their limits for compatibility are drawn on the basis of established performance criteria. It is expected that the trend for newly signalled interoperable lines will be fitted with types that meet the compatibility limits published in the TSI CCS Interfaces Document (ERA/ERTMS/033281). To ensure adequate operational availability, it is essential that the rolling stock complies with the defined limits; otherwise, the established availability of the valid output function of axle counter detectors may be compromised.

Železniške naprave - Medobratovalnost voznih sredstev in sistemov za detekcijo vlaka - 3. del: Združljivost s števci osi

Za potrebe dokazovanja združljivosti tirnih vozil in detektorjev števila osi ta tehnična specifikacija opredeljuje mejne vrednosti motenj in metode za preverjanje emisij tirnih vozil. Ta tehnična specifikacija ne zajema senzorjev na kolesih in kretnicah. Ta tehnična specifikacija določa priporočene individualne omejitve, ki jih je treba uporabljati pri določanju združljivosti med sistemi za zapisovanje podatkov (RST) in izbranimi vrstami detektorjev števila osi, vključno s tistimi, ki jih zajemajo nacionalni standardi. Seznam izbranih vrst števcev osi in njihovih omejitev glede združljivosti je sestavljen na podlagi uveljavljenih meril učinkovitosti. Pričakuje se, da bo trend na novo označenih medobratovalnih prog opremljen z vrstami, ki so skladne z omejitvami glede združljivosti, objavljenimi v dokumentu o vmesnikih (ERA/ERTMS/033281) tehničnih specifikacij za interoperabilnost (TSI CCS). Da bi zagotovili ustrezno operativno razpoložljivost, je bistveno, da so tirna vozila skladna z opredeljenimi omejitvami; v nasprotnem primeru je lahko ogrožena uveljavljena razpoložljivost izhodne funkcije števcev osi.

 Annexes B to D have been deleted.
This Technical Specification is Part 3 in the following series:

 CLC/TS 50238-2, Railway applications – Compatibility between rolling stock and train detection
systems – Part 2: Compatibility with track circuits;
 CLC/TS 50238-3, Railway applications – Compatibility between rolling stock and train detection

Introduction
This Technical Specification defines the interference limits and evaluation criteria for electromagnetic
compatibility between rolling stock and axle counter detectors.
The limits have been defined on the basis of a test specification described in prEN 50617-2:2013 [2] (cf.
CLC/SC9XA/Sec0779/CD) (laboratory tests).
This Technical Specification defines
 a set of interference limits for magnetic fields resulting from both rail current and equipment on board the
vehicles,
 evaluation criteria to verify rolling stock emissions and demonstrate compatibility with the interference
limits for magnetic fields,
 traceability of requirements (type of axle counter detectors considered for the limits).
In the relevant frequency range of the axle counter detectors, the magnetic field is dominant and only this type
of field is considered. Experience has shown that the effects of electric fields are insignificant and therefore
not considered.

1 Scope
For the purpose of demonstrating compatibility between rolling stock and axle counter detectors, this
Technical Specification defines the interference limits and evaluation methods to verify rolling stock emissions.
Wheel sensors and crossing loops are not covered by this Technical Specification.
This Technical Specification gives recommended individual limits to be applied to establish compatibility
between RST and all selected types of axle counter detectors, including any covered by national standards.
The list of selected types of axle counters and their limits for compatibility are drawn on the basis of
established performance criteria. It is expected that the trend for newly signalled interoperable lines will be
fitted with types that meet the compatibility limits published in the TSI CCS Interfaces Document
(ERA/ERTMS/033281).
To ensure adequate operational availability, it is essential that the rolling stock complies with the defined
limits; otherwise, the established availability of the valid output function of axle counter detectors may be
compromised.
NOTE The influences from metal parts or inductively coupled resonant circuits on the vehicle, eddy current brakes or
magnetic brakes, are not covered by this Technical Specification but are considered on the basis of national technical
specifications.
