<p>PROBLEM TO BE SOLVED: To provide a train radio system capable of restarting communication without searching for a radio base station to communicate with when the communication recovers (for example, when a train enters a radio train control section again).SOLUTION: On-train control devices 67a, 67b and on-train radio devices 61a, 61b are provided on one of the head vehicle and tail vehicle of a train 6. The on-train control device 67a holds frequency information (frequency f1) that the train 6 communicates with a radio base station when exiting from a radio train control section, and when the train 6 enters the radio train control section, the on-train control device 67b on the ongoing side of the train 6 outputs the frequency information (frequency f1) to the on-train radio device 61b so as to restart the communication with a ground control device through the radio base station.</p> |
