Hi Signalling Professionals:
Recently, I have encountered a track circuit design philosophy which I have doubted the actual benefit that it brings to the railway system.
is it better to implement track circuit with redundant function ? (that's if one track receiver fails, the system will automatic change to other receiver unit for the same track circuit, so the track circuit will work normally as usual). Anyone got ideas ? or has anyone seen this kind of design philosophy implemented for track circuit ?
