The wireless relay device according to the present disclosure includes: a reception unit to receive train control information; an information classification unit to classify the train control information into first control information requiring immediacy and second control information not requiring immediacy; a message generation unit to generate one message from the first control information contained in a piece of the train control information and to generate one message from a plurality of pieces of the second control information contained in a plurality of pieces of the train control information; and a transmission unit to transmit the messages generated by the message generation unit. With this configuration, it is possible to reduce the number of the data transfer messages which does not require immediacy while the instantaneous communication for the control information which requires immediacy is maintained.
