    Abstract: A system includes a drive system having one or more traction motors coupled in driving relationship to a plurality of wheels of a vehicle system. The traction motors are configured to provide both motive power for the vehicle system in a propel mode of operation and retarding effort to brake the vehicle system in a braking mode of operation. The system further includes a parking brake for maintaining a static position of the vehicle system when in an engaged state, and a controller configured to detect when the parking brake is in the engaged state. The controller is further configured to control at least one of the one or more traction motors to provide a braking effort to resist movement of the vehicle system when the parking brake is in the engaged state.

    Abstract: An apparatus for lifting and moving an axle of a rail vehicle includes a frame, a pair of rollers rotatably mounted to the frame to movably support the frame on a railroad track rail, and a pair of wedges mounted to the frame having mutually opposed ramped faces. The pair of wedges adjustable along the frame between a first position in which the ramped faces bracket, but do not contact, a rail vehicle wheel that rests on the track rail, and a second position in which the ramped faces engage the circumference of the wheel to support the wheel at a height above the railroad track rail. The apparatus further includes at least one jacking device for urging the wedges toward one another from the first position to the second position.
