Centralized Traffic Control 1. Traffic control system (TCS) or centralized traffic control (CTC) is a block system under which train movements are authorized by block signals whose indications supersede the superiority of trains for both opposing and following movements on the same track. FRA 236.828 2. Signal control – train movements are controlled by signal […]

Railway Interlocking of Level Crossing Gate LC gate LC gate interlocking method – I 1. The level crossing annunciation relay (LCAR) is kept normally energized in the gate lodge when no route over the level crossing has been set. 2. Any route is set, the concerned ASR/TRSR/TLSR drops which in turn de-energizes LCAR. 3. This […]

Railway Signalling Equipment Treadle Presentation What is Treadle? A treadle is a mechanical or electrical device that detects that a train axle has passed a particular location. They are used where a track circuit requires re-inforcing with additional information about a train’s location, such as around an automatic level crossing, or in an annunciator circuit, that sounds a warning […]
