A railway vehicle (11) comprising a safety relevant component (19) providing status data about its operation, a diagnosing device (21) controlling said safety relevant component (19), processing said status data and generating diagnosis data about the railway vehicle condition, a safety relevant data network (13) interconnecting the safety relevant component (19) and the diagnosing device (21), an information data network (15), a transmitting device (29) sending data from the railway vehicle (11) to a remote back office (10), which is part of the information data network (15), and a unidirectional security gateway (43) interconnecting the safety relevant data network (13) and the information data network (15), which only allows data communication from the former to the latter and relays said diagnosis data from said diagnosing device (21) to the information data network (15). Said transmitting device (29) sends the diagnosis data to the back office (10). |
