Abstract: A first locomotive that includes a control unit is disclosed. The control unit may receive a power demand, determine a first power limit of the first locomotive, and receive a second power limit of a second locomotive and a third power limit of a third locomotive. The control unit may proportion the power demand into a first power allocation for the first locomotive, a second power allocation for the second locomotive, and a third power allocation for the third locomotive. The control unit may adjust the first power allocation based on the first power limit, adjust the second power allocation based on the second power limit, and adjust the third power allocation based on the third power limit. The control unit may cause an action to be performed in connection with the first power allocation, the second power allocation, and the third power allocation.
