PROBLEM TO BE SOLVED: To provide a train radio system capable of avoiding a detection error of communication abnormality during end exchange.SOLUTION: The train radio system comprises: a ground control device; a radio base station 1; plural on-vehicle radio devices 5, 8 for performing radio communication between them and the radio base station 1 mounted on a train 100; and plural on-vehicle controllers 6, 7 connected to the respective on-vehicle radio devices 5, 8. The ground control device applies a control serial number N which is counted up for every generation of A→B information 12 to the A→B information 12 and then transmits the control serial number to the train 100. The on-vehicle control device 6 creates a transmission stop command 14 and creates a transmission start command 15 when a value of the control serial number N reaches a value of a switch timing serial number TN after completion of control platform switching. |
