To provide a communication relay device for a train and a communication relay method thereof making it possible to perform communications between devices and facilitate management of communication identification information even when communication identification information such as a redundant IP address is given to the same type of devices installed in different vehicles, and making it possible to perform a flexible operation at the time of merging or dividing of vehicle formations. When data is transmitted from a communication terminal (4a) to a communication terminal (4b), a communication relay device (1a) converts car identification information of a communication source of communication-source identification information included in a communication packet into a car number of a vehicle (9), and transmits the data to an inter-vehicle communication path (2a). When data is transmitted from the communication terminal (4b) to the communication terminal (4a), the communication relay device (1a) converts car identification information of a communication destination of communication-destination identification information included in a communication packet into a "0"-th car indicating own car, and transmits the data to an in-vehicle communication path (3a).
