A communication system for transferring communication within a railway train comprises a data bus (ETB, ECN) adapted to transfer data according to the Internet Protocol via point-to-point connections. Devices (A1, A2) are connected to the data bus (ETB, ECN), wherein the devices (A1, A2) are adapted to receive and/or send safety-relevant data (e.g. braking, door control) via the data bus (ETB, ECN). The data bus may be in a ring (2,3,4,5) featuring ring switches (RS), allowing data to be sent along multiple paths, and such rings in each carriage or group of carriages are connected to a backbone bus (ETB) running throughout the train, and connected via train switches (TS). |
