Abstract
1,199,353. Track circuits. WESTINGHOUSE ELECTRIC CORP. 18 July, 1968 [23 Aug., 1967], No. 34249/68. Heading B7N. In a track signalling system wherein the rails are electrically continuous and carry traction current, the track circuits are defined by shortcircuit members 24, 26 connected across the rails and adjacent circuits are operated on different frequencies. Signal transmitter 16 operating at frequency F 1 , feeds a loop 18 coupled to the rails at short-circuit 26 and the associated receiver 22 is fed from a loop 20 coupled to the track circuit at short-circuit 24. Additional receivers coupled to the rails may be provided intermediate the ends of the circuit to indicate which part of the circuit is occupied by a train. For additional security the circuit transmitters are modulated and the receivers give a clear indication only when both carrier and modulation is present and the modulation is comparable with the known modulation transmitted. The modulation is used for train command purposes.
