Abstract: A method of moving a charging assembly to engage a vehicle is provided. The method may include driving an upper arm of the charging assembly with an actuator, moving a lower arm and a passive linkage using a force from the upper arm and the actuator, and extending or retracting the passive linkage using the force from the upper arm and the actuator. The method may include sensing one or more electrical characteristics of the charging assembly. The method may include engaging a stop of the passive linkage to allow a substantially vertical movement of a charging head of the charging assembly responsive to the electrical characteristics being below a threshold. The method may include moving the passive linkage away from the stop to allow a substantially horizontal movement of the charging head responsive to the electrical characteristics being at or above the threshold.

Abstract: A door monitoring system may include an optical sensor that may generate sensor signals indicative of a field of view of the optical sensor. The field of view may include at least part of an interior vehicle floor in front of a vehicle door. The system also may include controller that receives the sensor signals and that detects a presence or absence of one or more persons and/or objects within the field of view of the optical sensor. The controller may change a speed at which the vehicle door moves based on the presence or the absence of the persons and/or objects that are detected responsive to detecting the presence or absence of the persons and/or objects.

Abstract: A locomotive control system includes an operation manager controller electrically coupled to an operator controller of a locomotive and to a local vehicle control system of the locomotive. The operation manager controller receives an operator command from the operator controller and can regulate the operator command to control operation of the locomotive.
