摘要

An object is to improve the arrival rate of communication data used for train control between a ground wireless base station and an on- vehicle wireless station. A train control system controls an operation of a train 11 by transmitting and receiving, between an on- vehicle wireless station 21 mounted on the train 11 and a ground wireless base station 31, information that includes train control information by wireless communication, the train control information being information for controlling an operation of the train 11. general transmission information Ul, which is information included in the information that includes the train control information and is transmitted only once from the ground wireless base station 31 to the on-vehicle wireless station 21. The train control information CI is transmitted repeatedly a plurality of times from the ground wireless base station 31 to the on-vehicle wireless station 21. Among the repeatedly transmitted train control information CI, the on-vehicle wireless station 21 uses, for an operation of the train 11, a piece of train control information CI, which the on-vehicle wireless station receives without lack of data lack for a first time.
