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.

Abstract: A control system for remotely configuring a locomotive includes a plurality of operational control devices located on-board the locomotive, the plurality of operational control devices being configured to implement a change to a designated configuration of the locomotive. A controller located on-board the locomotive is configured to activate the plurality of operational control devices to change the designated configuration of the locomotive upon receipt of a configuration command signal. An off-board remote user interface located remotely from the locomotive is configured to receive a single input from a user commanding a change in configuration of the locomotive, the single input being implemented by activation of a single input device on the remote user interface, and selectively send a configuration command signal to the on-board controller to activate the plurality of operational control devices to change the designated configuration of the locomotive.

Abstract: A cryogenic fluid system includes a vessel and a pumping system positioned for submerging within cryogenic fluid within the vessel. The pumping system includes an electric drive structured to move a pumping element within a pumping chamber to pump cryogenic fluid out of the vessel. A cooling jacket forms a heat exchange cavity about the electric drive such that heat is rejected externally of the storage vessel.

Abstract: A power system for a locomotive includes a dynamic brake (DB) grid, at least one chopper circuit, and a controller. The locomotive includes at least one traction motor to power one or more loads during a braking of the locomotive. The DB grid includes at least one resistor bank and is configured to dissipate at least a portion of the power generated by the traction motor. The chopper circuit includes a three-phase inverter module, and selectively disables an electrical communication between the resistor bank and the traction motor. The controller is coupled to the chopper circuit and the loads. The controller determines a magnitude of the loads, and controls the chopper circuit to disable an electrical communication between the resistor bank and the traction motor for a predetermined duration to control a portion of the power dissipated by the DB grid to meet the magnitude of the loads.
