Abstract
A system for communicating track information within a consist having at least a first and second locomotive may include a first transceiver associated with the first locomotive and configured to receive the track information from a remote transceiver. The system may include a communication link connecting the first locomotive with the second locomotive and a communication controller associated with the first locomotive. The communication controller may be configured to identify a lead locomotive and send a signal to the lead locomotive indicating that the track information is fully received from the remote transceiver. The communication controller may be configured to, if the lead locomotive is a locomotive other than the first locomotive, send the track information to the lead locomotive via the communication link, and if the lead locomotive is the first locomotive, send at least a portion of the track information to the second locomotive via the communication link.
