SGCP 4000/MS 4000 simple grade crossing predictor/motion sensor

Operation of the SGCP 4000/MS 4000 system is based on the maximum impedance of an unoccupied track circuit, which is determined by the location of termination shunts and rate of change in impedance resulting from the physical location of a train as it moves within a track circuit. The system applies a constant current AC signal to the track and measures the level of the resulting voltage. These levels vary with approaching track impedance, which also varies due to the distance of the train from the crossing. This is how the system detects inbound motion of a train and activates the crossing warning equipment.
