    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.

    Abstract: A cryocooler assembly for cooling a field winding of an electrical machine having an axis of rotation is provided. The assembly includes a cryocooler and a reservoir coupled in flow communication to the cryocooler and configured to contain a cooling agent. A flow assembly is coupled in flow communication to the reservoir. The flow assembly includes a first flow loop coupled in flow communication to the reservoir; a second flow loop coupled in flow communication to the reservoir; and a plurality of flow members coupled in flow communication to the first flow loop and the second flow loop and coupled to the field winding. Each flow member is configured to thermosiphon the cooling agent in a first state from the reservoir and in a second state to the reservoir.
