PROBLEM TO BE SOLVED: To provide a train position detection system capable of detecting the train position by using passing information obtained when a train passes through a point with a ground marker installed thereon and position information of the ground marker stored in an onboard device. SOLUTION: An onboard device 11, a receiver 12 for a ground marker, and a track digital information receiver 13 are equipped on a train 1, a ground marker 33 to transmit passing information to the onboard device 11 is installed on a track circuit 3, and a ground device 31 to transmit the track digital information Tdi including position information (marker position information) on the ground marker to the onboard device 11 is provided. Marker position information included in the track digital information Tdi is stored in the onboard device 11, and the position of the train is detected from position information of the ground marker stored in the onboard device 11 by using passing information from the ground marker 33.
