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.

    【課題】通信復旧時(例えば、列車が無線列車制御区間内に再進入した時)に通信すべき無線基地局を探索することなく、通信を再開することができる列車無線システムを得ること。【解決手段】車上制御装置67a,67b及び車上無線装置61a,61bは、列車6の先頭車両及び最後尾車両の少なくともいずれかに設けられ、車上制御装置67aは、列車6が無線列車制御区間から進出する時に無線基地局と通信している周波数情報(周波数f1)を保持し、列車6が無線列車制御区間内に進入する時には、列車6の進行方向側の車上制御装置67bは、周波数情報(周波数f1)を車上無線装置61bに出力して無線基地局を介して地上制御装置と通信の再開を行う。【選択図】図4
