Train control system

Abstract

The train control system includes: an on-board device 3 mounted on a train 2 traveling on a predetermined track 1; a vehicle radio set 4 that transmits and receives information of the on-board device 3; wayside radio sets 5 each of which is disposed at a predetermined location on the ground to transmit information to and receive information from the vehicle radio set 4 information; a ground device 8 placed by the track 1 and connected to the wayside radio set 5; an operation controlling device 12 that transmits operation information of the train 2 to the ground device 8; and an interlocking device 11 that performs an operation control of a turnout 6 for switching tracks. The ground device 8 detects the location of the train 2 on the basis of wireless propagation time between the vehicle radio set 4 and the wayside radio set 5, receives entering track information of the train 2 from the operation controlling device 12, and controls an interval between a preceding train 2 and a following train 2.
