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 interference current emissions from rolling stock. The measurement and evaluation methods for verifying conformity of rolling stock to these limits in presented in a dedicated annex.
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 in a dedicated annex.
This Technical Specification 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 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.

Bahnanwendungen - Kompatibilität zwischen Fahrzeugen und Gleisfreimeldesystemen - Teil 2: Kompatibilität mit Gleisstromkreisen

Die vorliegende Technische Spezifikation legt – mit dem Ziel der Sicherung der Kompatibilität zwischen Fahr-zeugen und Gleisstromkreisen – die Grenzwerte für die Aussendung von Störströmen durch Fahrzeuge fest. Die Mess- und Bewertungsverfahren für den Nachweis der Einhaltung dieser Grenzwerte durch die Fahrzeuge sind in einem zugehörigen Anhang dargestellt.
Die Beeinflussungsgrenzwerte gelten nur für interoperable Fahrzeuge, die für einen Einsatz auf Strecken bestimmt sind, die ausschließlich mit den in dieser Technischen Spezifikation aufgeführten bevorzugten Gleisstromkreisen ausgerüstet sind. „National Notified Technical Rules“ sind immer dann anzuwenden, wenn die Strecke, für deren Einsatz das Fahrzeug vorgesehen ist, mit einer älteren Version oder nicht bevorzugten Gleisstromkreisen, die nicht in dieser Technischen Spezifikation aufgeführt sind, ausgerüstet ist. Die in der vorliegenden Technischen Spezifikation angegebenen Prüfverfahren für Fahrzeuge (Infrastrukturbedingun¬gen, Prüfanordnungen, Betriebsbedingungen usw.) sind jedoch auch für die Ermittlung der Kompatibilität mit nicht bevorzugten Gleisstromkreisen anwendbar.
Diese Technische Spezifikation enthält einen Leitfaden für die Ableitung von Störstromgrenzen, die für Fahr-zeuge festgelegt sind, und sie definiert Messverfahren und Bewertungskriterien.
Diese Technische Spezifikation legt fest:
a)   eine Reihe von Störstromgrenzwerten für RST (en: Rolling Stock; de: Fahrzeuge), welche für die folgenden Arten von Traktionssystemen gelten:
1)   Gleichspannung (750 V, 1,5 kV und 3 kV);
2)   Wechselspannung 16,7 Hz;
3)   Wechselspannung 50 Hz;
b)   Verfahren für den Nachweis der Kompatibilität zwischen Fahrzeugen und Gleisstromkreisen;
c)   Messverfahren für den Nachweis der Störstromgrenzwerte und Bewertungskriterien.
ANMERKUNG 1   Die Grundparameter von Gleisstromkreisen im Zusammenhang mit Störstromgrenzwerten für RST gehören nicht zum Anwendungsbereich der vorliegenden Technischen Spezifikation.
ANMERKUNG 2   Vorgänge im Zusammenhang mit der Traktionsstromversorgung und der zugehörige Schutz (Überspan¬nung, Kurzschlussstrom, Unter- und Überspannung bei Verwendung von Nutzbremsen) gehören zur Auslegung des Gleisstromkreises und sind nicht Bestandteil dieser Technischen Spezifikation.

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

Ta tehnična specifikacija opredeljuje omejitve oddajanja motečega toka iz voznih sredstev za namene združljivosti med voznimi sredstvi in tirnimi tokokrogi. Metode merjenja in ocenjevanja za preverjanje skladnosti voznih sredstev s temi omejitvami so predstavljene v ustreznem dodatku.
Omejitve motenj veljajo samo za interoperabilna vozna sredstva, namenjena obratovanju na linijah, ki so posebej opremljene s prednostnim tirnim tokokrogom, ki je naveden v tej tehnični specifikaciji. Priglašena nacionalna tehnična pravila se morajo še vedno upoštevati v primerih, če je linija, na kateri obratujejo vozna sredstva, opremljena s katerokoli starejšo ali neprednostno različico tirnega tokokroga, ki ni navedena v tej tehnični specifikaciji. Vendar se metodologija voznih sredstev (infrastrukturni pogoji, preskusne konfiguracije, obratovalni pogoji itd.), ki je predstavljena v tej tehnični specifikaciji, uporablja tudi za določanje združljivosti z neprednostnimi tirnimi tokokrogi.
Ta tehnična specifikacija podaja smernice za izpeljavo omejitev motečega toka, ki so navedene za vozna sredstva, ter opredeljuje metode merjenja in kriterije ocenjevanja v ustreznem dodatku.
Ta tehnična specifikacija določa:
a) omejitve motečega toka za vozna sredstva (RTS), ki veljajo za vsako od naslednjih vrst vlečnega sistema:
1) sistem z enosmernim tokom (750 V, 1,5 kV in 3 kV);
2) sistem z izmeničnim tokom in frekvenco 16,7 Hz;
3) sistem z izmeničnim tokom in frekvenco 50 Hz;
b) metodologijo za prikaz združljivosti med voznimi sredstvi in tirnimi tokokrogi;
c) metode merjenja za preverjanje omejitev motečega toka in kriterije ocenjevanja.
OPOMBA 1: Osnovni parametri tirnih tokokrogov, ki so povezani z omejitvami motečega toka za RTS, ne spadajo na področje uporabe te tehnične specifikacije.
OPOMBA 2: Vsi pojavi, povezani z vlečnim napajalnim sistemom in z njim povezane zaščite (prenapetost, kratkostični tok, upad napetosti ali prenapetost pri uporabi regenerativnih zavor), so del zasnove tirnega tokokroga in ne spadajo na področje uporabe te tehnične specifikacije.

1 Scope
This Technical Specification 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 interoperable rolling stock which is intended to run on lines
exclusively equipped with preferred track circuits 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 in a dedicated annex.
This Technical Specification 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.

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
2)
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
