What is BS EN 50617-1 - Track circuits about?
BS EN 50617 discusses technical parameters of train detection systems for the interoperability of the trans-European railway system. BS EN 50617-1 outlines the technical parameters of track circuits associated 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 BS EN 50617-1 allow provision for known interference phenomena linked to the 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.
BS EN 50617-1 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 technical specification for interoperability relating to the control-command and signalling track-side subsystems.
BS EN 50617-1 describes technical parameters to consider for achieving the compatibility of the track circuit with the emissions limits defined in the frequency management for rolling stock
BS EN 50617-1 is applicable to track circuits installed on all traction power supply lines, including non-electrified lines.
Note: However, for track circuits intended to be installed only on non-electrified lines, some parameters may be not applicable.
Who is BS EN 50617-1 - Track circuits for?
BS EN 50617-1 on train detection systems for the interoperability of the trans-European railway system is useful for:
- Regulatory authorities
- Test centres
Why should you use BS EN 50617-1 - Track circuits?
BS EN 50617-1 guideline assists you with a description of the train detection system, safety relevance of parameters, technical track circuit parameters, IRJ failure detection, the response of the receiver to transient disturbances, train-based parameter - shunt impedance, track-based parameters, environmental, and other parameters for train detection systems for the interoperability of the trans-European railway system for track circuits.
This will support you to meet requirements for compatibility between train detection systems and rolling stock in the future. And will encourage you to achieve interoperability.
