To provide a train radio system capable of smooth radio communication in response to a plurality of railway operators that use mutually different communication methods and provide inter-connected through services.SOLUTION: In a train radio system 1001 of the present disclosure, a radio device 701 mounted on a train 11 includes a main radio unit 73 and a sub radio unit 74. The main radio unit 73 wirelessly communicates with a plurality of company A base stations 2a using a company A communication method while the train 11 is traveling on a company A operation line SA. The sub radio unit 74 is in a standby state for communication using the company A communication method until the train 11 reaches a first switching point D1, which is a predetermined distance before, from a boundary C between the company A operation line SA and a company B operation line SB, and switches the communication method from the company A communication method to the company B communication method when the train 11 reaches the first switching point D1.SELECTED DRAWING: Figure 1

    【課題】本開示は、通信方式が異なり相互乗り入れを行う複数の鉄道事業者に対応して円滑な無線通信が可能な列車無線システムの提供を目的とする。【解決手段】本開示の列車無線システム1001において、列車11に搭載された無線装置701は、主無線部73および副無線部74を備える。主無線部73は、列車11がA社運行路線SAを走行中にA社通信方式で複数のA社基地局2aと無線通信する。副無線部74は、列車11がA社運行路線SAとB社運行路線SBとの境界Cから予め定められた距離だけ手前側の第1切替地点D1に到達するまで、A社通信方式での通信の待機状態であり、列車11が第1切替地点D1に到達した場合に、通信方式をA社通信方式からB社通信方式に切り替える。【選択図】図1
