BS EN 50617-1:2015EN 50617-1:2015 (E) 6 Introduction The working group SC9XA WGA4-2 has developed the limits for electromagnetic compatibility between rolling stock and train detection systems, specifically track circuits and axle counter sys
24、tems and correspondingly published two technical specifications CLC/TS 50238-2 and CLC/TS 50238-3. These limits and associated measurement methods are based on preferred existing systems (as defined in CLC/TS 50238-2 and CLC/TS 50238-3) which are well established and still put forward for signalling
25、 renewals by infrastructure managers. To meet the requirements for compatibility between train detection systems and rolling stock in the future and to achieve interoperability and free movement within the European Union, it is necessary to define a “Frequency management” including the complete set
26、of interface requirements. The train detection systems, track circuits and axle counters, are an integral part of the CCS trackside subsystem in the context of the Rail Interoperability Directive. The relevant technical parameters are enumerated in the CCS and LOC - train based parameters; - track b
27、ased parameters; - environmental and other parameters. Where possible, the parameters as defined are consistent with other European Standards. Each parameter is defined by a short general description, the definition of the requirement, the relation to other standards and a procedure to show the fulf
28、ilment of the requirement as far as necessary. An overview of the safety relevance of each parameter is given in the context of this European Standard in a separate table. BS EN 50617-1:2015EN 50617-1:2015 (E) 7 1 Scope This European Standard specifies the technical parameters of track circuits asso
29、ciated with the disturbing current emissions limits for RST in the context of interoperability defined in the form of Frequency Management. The limits for compatibility between rolling stock and track circuits currently proposed in this standard allow provision for known interference phenomena linke
30、d to traction power supply and associated protection (over voltage, short-circuit current and basic transient effects like in-rush current and power cut-off). These effects are assessed using modelling tools that have been verified by the past European research project RAILCOM. This European Standar
31、d is intended to be used to assess compliance of track circuits equipment and other forms of train detection systems using the rails as part of their detection principles, in the context of the European Directive on the interoperability of the trans-European railway system and the associated technic
32、al specification for interoperability relating to the control-command and signalling track-side subsystems. The European Standard describes technical parameters to consider for achieving the compatibility of the track circuit with the emissions limits defined in the frequency management for rolling
33、stock. These parameters are structured and allocated according to their basic references as follows: - Technical track circuit parameters; - Train based parameters; - Track based parameters; - Environmental and other parameters including EMC. Each parameter is defined by a short general description,
34、 the definition of the requirement, the relation to other standards and a procedure to show the fulfilment of the requirement as far as necessary. An overview of the safety relevance of each parameter is given in the context of this European Standard in a separate table. NOTE The allocated bands for
35、 track circuits and emission limits for rolling stock defined in the Frequency Management are currently used as input information to define mandatory requirements to be stated in index 77 of CCS TSI. The evaluation is conducted by the European Railway Agency. The immunity limits of the track circuit
36、s installed on non-interoperable lines, or on interoperable lines built before the publication date of this document, are not defined in this European Standard and remain the responsibility of individual infrastructure managers, NSAs and/or suppliers of train detection systems. In this case, the lim
37、its for compatibility are usually given in the infrastructure registers and/or the notified national rules. This European Standard is applicable to track circuits installed on all traction power supply lines, including non-electrified lines. However, for track circuits intended to be installed only
38、on non-electrified lines, some parameters may be not applicable. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
