Train control system and train control method

Abstract

A train control system includes: a plurality of trains; a train operation control device that identifies a relief-object train that is a train having failure and determines a relief train that is a train that moves on to the relief-object train to relieve the relief-object train and a protective section in which the relief train can travel, on the basis of on-track information acquired from the trains; and a ground control device that sets, in the trains, the protective section determined by the train operation control device. The trains each transmit the on-track information including location information and failure information with use of which the train operation control device can determine a state of a failure when the failure occurs, to the train operation control device via the ground control device.
