Abstract

In a system and method for communicating data in a locomotive consist or other vehicle consist (comprising at least first and second linked vehicles), a first electronic component in the first vehicle of the vehicle consist is monitored to determine if the component is in (or enters) a failure state. In the failure state, the first electronic component is unable to perform a designated function. Upon determining the failure state, data is transmitted from the first vehicle to a second electronic component on the second vehicle, over a communication channel linking the first vehicle and the second vehicle. The second electronic component is operated based on the transmitted data, with the second electronic component performing the designated function that the first electronic component is unable to perform.
