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. 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.

Železniške naprave - Medobratovalnost voznih sredstev in sistemov za detekcijo vlaka - 2. del: Združljivost s tirnimi tokokrogi

Ta tehnična specifikacija za namen zagotavljanja združljivosti med voznimi sredstvi in tirnimi tokokrogi opredeljuje omejitve za direktno interferenco iz voznih sredstev in merilno metodo za preverjanje skladnosti voznih sredstev s temi omejitvami. Omejitve interference veljajo le za medobratovalna vozna sredstva, namenjena vožnji po linijah, opremljenih izključno s prednostnimi tirnimi tokokrogi, navedenimi v tej tehnični specifikaciji. V vseh primerih, ko je linija, po kateri bodo vozila vozna sredstva, opremljena s katero koli starejšo različico ali neprednostnimi tirnimi tokokrogi, ki niso navedeni v tej tehnični specifikaciji, se še vedno uporabljajo nacionalni tehnični predpisi. Metodologija preskušanja voznih sredstev (infrastrukturni pogoji, preskusne konfiguracije, operativni pogoji itd.), predstavljena v tej tehnični specifikaciji, velja tudi za ugotavljanje združljivosti z neprednostnimi tirnimi tokokrogi. Ta tehnična specifikacija podaja vodilo o izpeljavi omejitev interferenčnih tokov, določenih za vozna sredstva in opredeljuje merilne metode in merila vrednotenja.
