ABSTRACT:
A method and apparatus for determining the position of one or more locomotives in a train consist is disclosed. A receiver is mounted to each locomotive in a train consist. The receiver receives a signal such as a reference signal from a global positioning system determines a coordinate position for that locomotive. A processor determines a relative position for the locomotive in the train consist based on its determined coordinate position. This process is periodically repeated for each locomotive in the train consist so that the configuration of locomotives in the train consist may be tracked or verified as cars are added or removed from the train.
