Abstract (en)
[origin: CA1171162A] A railway track circuit is provided formed by the two rails of a railway track portion and comprising a transmitting member connected to the downstream end of the circuit and a receiving member connected to the upstream end. There is also at least one electromagnetic sensor disposed at a given position along the track circuit. A receiver is associated with this sensor and there are switching means for switching the transmitting and receiving members of the track circuit, after the receiver associated with the sensor, has been de-energized by the passage over the sensor of the first shunt axle carried by a train running over the track.
