A system and method which may include on each locomotive a propulsion system and a braking system, a transceiver for communication between the locomotives, and sensors for sensing operational conditions on the locomotive. A processor receives the sensed operation conditions, communicates information including the sensed operational conditions to the other locomotive, determines a propulsion or braking value or command based on the sensed operational conditions, pre-selected criteria and the information received from the other locomotive, and outputs the propulsion or braking value or command.
