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.

Power management system for a consist

A method for operating a consist is disclosed. The consist includes a number of locomotives. The method includes selecting a power setting in a lead locomotive of the consist to generate an overall power request by an input device. Thereafter, a controller determines a power setting in each locomotive based on the overall power request. Next, the controller modulates a power output of one or more locomotives according to a difference between a measure of the overall power request and a measure of a combined power output of all locomotives according to the power setting determined by the controller, such that the combined power output matches the overall power request by keeping the power setting, determined by the controller, of each of the one or more locomotives unchanged.

Consists with linear throttle mapping

A system for adjusting wheel adhesion levels on multiple locomotive axles in a rail vehicle consist is provided. The system includes a first controller associated with a lead locomotive and a second controller associated with at least one trailing locomotive. A wheel adhesion level sensor is configured to detect a low wheel adhesion level at an axle and transmit that information to the first or second controller. The first controller adjusts the load being delivered to the axles by the motor in response to the low wheel adhesion level.

Consist adhesion level control system for locomotives

A rail vehicle consist may include a master unit and at least one trailing unit coupled to the master unit. The master unit may include a first processor in communication with a second processor of the at least one trailing unit. A power source may be disposed on the at least one trailing unit and may include a sensor associated with the second processor. A display may be disposed on the master unit and may be associated with the first processor to display characteristics monitored by the sensor wherein the display presents a message image, a warning image, and an isolate image.
