Abstract

See full text

Transceivers may be used in track circuits. A transceiver may comprise an H-bridge circuit comprising at least four switches. A control unit in communication with the H-bridge circuit may be constructed and arranged to selectively drive the at least four switches to selectively cause the H-bridge circuit to function as a transmitter or a receiver. A power supply terminal in communication with the H-bridge circuit may be constructed and arranged to connect to a power supply. A track interface terminal in communication with the H-bridge circuit may be constructed and arranged to connect to a track interface cable so that the H-bridge circuit is capable of transmitting signals to and/or receiving signals from the track interface cable.
