IPC: B61L1/14
Filed: 1992-04-28
Abstract: A railway signal system for detection of the passage of a complete train in regions where there is no provision of continuous track circuits. Each train (1) is fitted at front and rear with a permanent magnet switching member (9, 13). The track section which has to be known to be clear of the train has a transponder (21, 23) at each end which, when energised, transmits to a receiver (15) on the train its own address and condition. The front end magnet (9), on passing the first transponder (T1) enables it and disables the second transponder (T2). When the rear magnet (13) passes the first transponder (T1), the second transponder (23) is enabled to transmit a signal to the train saying the complete train is in the section. Each transponder, instead of being selectively enabled or disabled, may be selectively switched to transmit a first or second code. <IMAGE>
