Abstract

1,178,375. Train control. WESTING- HOUSE ELECTRIC CORP. 11 March, 1968 [11 May, 1967], No.11711/68. Heading B7N. Apparatus for determining from a wayside control station the position and speed of a train in a signalling block comprises a transmitter 12 on the train coupled via coil 10 to two twin conductor trackside cables 14, 16, each of which has its conductors regularly crossed over 18 at points midway between the cross-overs of the conductors of the other cable and a wayside control station receiver connected to one end of the cables for detecting the phase reversals in the received signals. The other end of each cable is short-circuited and the receiver includes input transformers 34, 36, input filters 38, 40 and a phase-sensitive detector 42. The detector supplies output pulses the number and frequency of which are a function of the distance travelled by the train in the block and its speed. Signals can be passed to a receiver 60 on the train from a transmitter 50 at a local control station via centre-taps of the primaries of the receiver input transformers.
