摘要： A system includes a track system having a first rail and a second rail, a track activity detection circuit electrically connected to each of the first rail and the second rail, a track shunt circuit electrically connected to the first rail and the second rail, wherein the track shunt circuit is configured to selectively electrically connect the first rail and the second rail through a shunt. A method includes receiving an instruction to apply a shunt between a first rail and a second rail of a track system, and electrically connecting the first rail to the second rail through a controllable track shunt circuit.

摘要： A system is provided for temporary protection operation of at least one controller box for a railroad switch turnout in a powered mode or non-power mode depending on the railroad configuration and independent of the controller box. A normal controller box is coupled to the normal switch point and includes a block slidably received within the housing based on moving the normal switch point to establish at least one pair of electrical contacts within the housing. A controller is coupled to the controller box to verify a pair of compressed contacts to determine that the normal switch point has moved to the normal position to cause the controller box to send an open signal to a pair of switch connections. The controller also verifies a pair of extended contacts to determine that the normal switch point has failed to move to the normal position to omit to cause said controller box to send an open signal to the pair of switch connections and maintain each respective switch connection to shunt the stationary stock rails.

摘要： In the state that a train moves from a track circuit 3T toward a track circuit 5T, and a train detection signal TD1 is supplied from the boundary between the track circuits 3T and 5T to the track circuits 3T and 5T, and the train detection signal TD1 is received by the train, if the signal intensity is suddenly reduced greatly immediately after the axle of the train passes the boundary between the track circuits 3T and 5T, it can be decided that the train passes the boundary between the track circuits 3T and 5T. Therefore, if absolute position information of the track circuit 5T is preserved beforehand in the train, the movement distance calculated from pulse output of a speed generator is corrected (replaced) in the absolute position information of the track circuit 5T, and hereafter is updated by the pulse output, thus the position of the own train can be easily detected as a movement distance.
