Abstract

A method for determining a sequence of railcars (14, 16, 18, 20) connected to a locomotive (12) on a train (10), wherein a control device (28) of the locomotive (12) is connected to railcars (14, 16, 20) comprising a control device (30, 32, 34) via a brake pipe (22), wherein the control device (28) of the locomotive (12) and the control devices (30, 32, 34) of the railcars (18, 16, 20) may exchange messages via a fast wireless network (52), comprises the following steps: Transmitting, by the control device (28) of the locomotive (12) of a unique identification code to the control devices (30, 32, 34) via a slow network constituted by the brake pipe (22); Transmitting, by the control device (28) of the locomotive (12) over the fast network, of messages indicative of a current state of the transmission carried out via the slow network, wherein the messages comprise the unique identification code; Determining, by the control devices (30, 32, 34), of a time delay between the state of the transmission received from the control device (28) and a state of the transmission measured on the slow network; Calculating a distance of each railcar (14, 16, 20) to the locomotive (12) from the time delay and a propagation velocity of the slow network; Requesting, by the control device (28) of the locomotive (12) of a report relating to the calculated distance and/or measured time delay by each railcar (14, 16, 20); Sending, by the control device (30, 32, 34), a report in response to the above request, if an identification code in the request matches an identification code received via the slow network and Ordering the railcars (14, 16, 20) by their distance to the locomotive (12). A Control device (30, 32, 34) for a railcar (14, 16, 20), wherein the control device (30, 32, 34) comprises a pressure sensor (38, 40, 42) for detecting pressure changes within a brake pipe (22) connected to a locomotive (12), wherein the control device (30, 32, 34) is configured to decode an identification code of the locomotive (12) encoded in the pressure changes, wherein the control device (30, 32, 34) further comprises a communication unit (46, 48, 50) for communicating over a wireless communications network (52) and wherein the control device (30, 32, 34) is configured to only respond to requests from a locomotive (12) if an identification code sent with such a request corresponds to the identification code decoded from the pressure changes.
