PURPOSE: To provide an information transmission system for a railway vehicle which can rapidly and accurately execute the operation of various vehicle formation (integration or division of formed vehicles) on the way of operating drive and in which a bottleneck does not occur in an information transmission capacity between information communication networks in the formed vehicle. CONSTITUTION: When a plurality of information communication networks 20 in a formed vehicle are cascade connected between the networks in a predetermined order, an addition node address in which a predetermined offset address 32 is added to a reference node address 30 allocated to indoor units 24 of the information communication network 20b in the vehicle of a rear stage is reallocated to each indoor unit 24. The address 30 is used for the network 20a in the vehicle of a front stage, an addition node address is used for the network 20b in the vehicle of the rear stage, and hence a new single information communication network 20c for the vehicle is reconstructed. |
