Railway Signalling Level Crossing Interlocking Circuits • Connected Relays: • LXLR: This relay picks up by proving all concerned ASR/OVSRs of signals in whose route/overlap the L.C. gate falls are free.(i.e., picked up) and UCRs are de-energized (i.e., route is not set). • LXRR: It proves that the gate is free to be opened for […]

OVERLAP FLANK PROTECTION RAILWAY SIGNALLING OVERLAP The distance beyond a stop signal which must be clear and where necessary locked in order to clear previous signal. Background The purpose of an overlap is to provide an unobstructed portion of line beyond the exit signal reserved in case the train passes the exit signal at danger. […]

Principles of Train working and need for signalling All over the world Railway transportation is increasingly used, as this mode of transport is more energy efficient and environmentally friendly than road transportation. Trains move on steel rail tracks and wheels of the railway vehicle are also flanged Steel wheels. Hence least friction occurs at the […]
