Abstract

A train control system of the present invention includes: an on-board devicethat is mounted on a train and has an vehicle radio set VRScapable of performing wireless communication; fixed radio sets (WRSto WRS, and SRS) that are disposed along the railroad track R and capable of performing wireless communication by a time division multiple access method with the vehicle radio set VRS; and a ground devicethat calculates distance from a train A to a stop point before a preceding train B on the basis of the location information of the train A obtained by the wireless communication between the vehicle radio set VRSand the fixed radio set. The on-board devicegenerates a stop pattern on the basis of the distance, and performs a travel control so that the train A travels at a speed equal to or less than the stop pattern.
