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 e...
