An auxiliary drive axle assembly is disclosed for a railcar mover that provides traction for a railcar mover when required. The auxiliary drive axle assembly comprises a frame, a plurality of hydraulic motors, and a plurality of wheel assemblies positioned underneath a railcar mover. The auxiliary drive axle assembly may be lowered to a use position where the wheels engage the rails either upon demand by the railcar mover operator or automatically by a control system based upon a set of monitored parameters. When in a use position, the control system directs the power to the hydraulic motors such that the wheel assemblies can have optimal traction to assist the railcar mover.

A simulation system, device, and method for testing a train management system on a road-rail vehicle is provided. The simulation system includes: a brake pressure simulation device adapted to be connected to a first input of the train management computer, the brake pressure simulation device including at least one circuit configured to output signals representative of at least one brake pipe pressure; and a speed simulation device adapted to be connected to a second input of the train management computer, the speed simulation device configured to detect a speed of the road-rail vehicle and output signals representative of the speed. Also disclosed is a simulation system wherein the at least one circuit of the brake pressure simulation device is configured to have variable resistances.

A system for a well car includes a frame, a hitch coupled to the frame near the first end of the frame, and a first deck coupled to the frame. The frame includes a first pair of sockets located near a first end of the frame and a second pair of sockets located near a second end of the frame. Each socket of the first pair of sockets is configured to engage a support casting of a first pair of support castings located at a first position along a length of a well car. Each socket of the second pair of sockets is configured to engage a support casting of a second pair of support castings located at a second position along the length of the well car. The first deck is configured to hold wheels of a trailer when the trailer is coupled to the hitch.

A vehicle with a collapsible body. With this construction a one-person's vehicle can be folded together to a very compact size with the dimensions of an average suitcase. The body comprises two halves: a front and back part. Each of these parts contains a lower and upper hollow section. Each upper hollow section can slide telescopically in and out the lower hollow section, thus enlarging or reducing the length of the corresponding part. In the collapsed state both parts with all their sections are nested into each other. A further reduction of the volume of the collapsed vehicle can be achieved by using a chassis with two retractable slidable frame parts.

A railgear guide unit assembly for a road vehicle comprises a pair of rail wheels coupled to an axle, a first pair of pivotal links, and a second pair of pivotal links, wherein both pairs of pivotal links are coupled to the axle at one end. The assembly further comprises a pair of railgear pressure mechanisms, wherein the railgear pressure mechanisms each comprise an outer guide assembly, an inner guide translatable within the outer guide assembly, and a spring coupled to a first end of the inner guide to provide a compressive force on the inner guide. One end of each of the pair of pivotal links is coupled to a respective inner guide such that a movement of the inner guides of respective railgear pressure mechanisms corresponds to a movement of the respective pair of pivotal links.

Rail gear may facilitate a vehicle traversing on the rails of a railway. The rail gear may comprise a first rail guidewheel and a second rail guidewheel in rotatable connection with an axle. The rail gear may also comprise a first mount that is restricted from rotating with respect to the axle and a second mount that is configured to rotate with respect to the axle.

An urban rail transit vehicle includes a vehicle body, a plurality of driving rubber wheels and guiding steel wheels are installed on the bottom of the vehicle body; the plurality of driving rubber wheels are arranged along the length of the vehicle body, the plurality of guiding steel wheels are arranged along the length of the vehicle body; the vehicle body is provided with a first driving device for driving the guiding steel wheels to move up and down along the height of the vehicle body. In the urban rail transit vehicle provided by the present invention, guiding steel wheels capable of moving up and down are arranged on the vehicle body, realizing running on a railway line or an automobile transport road surface line, diversifying applications of vehicle and reducing construction cost.

A tamper apparatus configured for being transportable upon a road is provided. A chassis is configured for supporting the tamper apparatus. A retractable turntable unit is connected to the chassis. The turntable unit has a generally quadrilateral configuration with side walls, and is rotatably attached at substantially a center of mass of the tamper apparatus. A tamping unit is connected to the chassis and configured for performing packing of a ballast under railroad ties for correcting cross and longitudinal levels of a pair of rails of a railroad track. A buggy lift assembly is removably attached to the chassis and configured for providing track alignment of the rails. At least one set of retractable rail wheels is connected to the chassis such that the chassis is towable by an automobile.
