ABSTRACT:
A train position detection system which enables train position detection based on a combination of passing information obtained when a train passes over a point at which a ground marker is installed and position information about the ground marker stored in an onboard device. The onboard device, a ground marker receiver and a track digital telegram receiver are mounted on a train. A ground marker that transmits passing information to the onboard device is provided on a track circuit, and a ground device that transmits a track digital telegram containing position information about the ground marker (marker position information) to the onboard device is provided. The onboard device stores the marker position information contained in the track digital telegram, and the position of the train is determined based on the passing information transmitted from the ground marker and the position information about the ground marker stored in the onboard device.
