Abstract

985,385. Track circuits. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Dec. 10, 1962 [Dec. 13, 1962], No. 47109/62. Heading B7N. A track circuit comprises a track relay TR with a main winding 11 connected across the rails 1 and 2 and an auxiliary winding 9 connected in series with the feed circuit to the rails. The auxiliary winding opposes the effect of the main winding thereby extending the distance over which a train shunt is detected by the circuit. Fig. 2 (not shown) illustrates the use of the circuit in a level crossing control arrangement.
