Abstract

980,797. Automatic train control systems. WESTINGHOUSE AIR BRAKE CO. March 19, 1962 [April 10, 1961], No. 10333/62. Addition to 980,707. Heading B7N. In a modification of the automatic train control system described in the parent Specification, the co-operating train and track coils which signal the entry and exit of a train into and from a block section are replaced by a continuously operated carrier frequency transmitter 2CT on the train which supplies a signal modulated by a first tone in unit 2C1TT to aerial FANT at the front of the train and a signal modulated by a second tone in unit 2C2TT to aerial RANT at the rear of the train, the aerials couple to the block conductors and receive equipment is provided at each location, e.g. carrier receive apparatus R2C5 and associated tone receivers R2C1T5 and R2C2T5 at location 5, connected to the block conductor at the entrance end of the block. Furthermore, the train control signals from each location, e.g. generator 1CTT5 at location 5, are supplied to the exit end of the preceding block conductor BC4 and in addition to being received on the train are also received at location 4 by carrier receive unit R1C4 and associated tone receive equipment R1C1T4 and R1C2T4 connected to the entrance end of block conductor 4. Each location train control transmitter, e.g. 1CTT5, is capable of providing a No. 1 lowspeed tone, a No. 2 stick relay control signal and a No. 3 high-speed tone. Tones 1 and 3 are used for train control in the manner described in the parent Specification and tones 1 and 2 received at the entry end of a block are used, with the two tones received from the train when present, to determine the train control tones to be applied to the preceding block. With a train in block TS5, relays 2C1TR5 and 2C2TR5 associated with train tone receivers R2C1T5 and R2C2T5, respectively, are picked up, stick relay 5SR is released so that tone 2 only is applied to block conductor 4 and any train in block TS4 is controlled to a halt. With a train in block section TS6 (not shown) tone 2 only is received at location 5, relay 1C2TR5 and hence stick relay 5SR are picked up and tone No. 1 (slow speed) is applied to block conductor 4. With a train in block section TS7 (not shown) tone No. 1 is received at location 5, relay 1C1TR5 picks up and since stick relay 5SR is held by its stick circuit both tones No. 1 (low speed) and No. 3 (high speed) are applied to block conductor 4.
