Abstract
A railway communication system (10) includes a transmitter (12) receiving an input and producing a communication signal (18). The communication signal (18) includes at least two different portions (20,22) for separately encoding respective indications (38,40) of the input. The system also includes a receiver (14) coupled to a controlled device, the receiver (14) extracting at least one of the respective indications (38,40) from the communication signal (18). The receiver controls the device responsive to the at least one extracted indications (38,40).
