A system and method to move a load across a surface. The system has a track on the surface in a first direction, a track cart that moves the load in the first direction and a transfer cart that moves the load in a second direction on a separate cart path. The surface can be corrugated panels having upstanding ribs and the track can have a mounting assembly that mounts the track to the ribs. The track cart slides under the load, lifts the load off the ribs and moves the load in the first direction. The transfer cart is integrated into a gap in the track so the track cart can move over the transfer cart or stop on the transfer cart to move the load in the second direction on ribs defining the cart path. The method uses the components to move the load across the surface.

A railroad car truck bolster including a first end, a first diagonal member, a transitional concave first turn of spring seat, a center rib assembly, first and second diagonal ribs, and a bottom member. The center rib assembly includes first, second, and third center ribs and a U transition. The bottom member includes thickened walls that define brake rod holes. The first diagonal member is connected to the first end via the concave first turn of spring seat. The center rib assembly is connected to the first end, the straight first diagonal member, and the first turn of spring seat. The first, second, and third center ribs are connected to one another via the U transition. The first and second diagonal ribs are connected to the first turn of spring seat. The third center rib is between the first and second diagonal ribs. The bottom member is connected to the first diagonal member.

Vehicles for use on a railway and their methods of operation are disclosed. In one embodiment, a vehicle includes a bogie with wheels engaged with opposing tracks extending along a length of a railway the bogie travels along. The vehicle includes at least one sensor configured to sense a position of the bogie and/or wheels relative to the tracks of the railway. A processor of the vehicle uses the sensed position of the bogie and/or wheels relative to the tracks to steer the wheels of the bogie along a desired path on the tracks as the bogie travels along the railway.

A rubbing plate of a side bearer of a railcar bogie is a rubbing plate of a side bearer provided at the railcar bogie so as to slidably contact a slide member arranged above or under the side bearer. The rubbing plate includes a recess-projection provided on an opposing surface of the rubbing plate, the opposing surface being opposed to a sliding surface of the slide member.

A railcar bogie includes a cross beam, an axle box, a supporting member, a plate spring, and an axle beam. The axle box accommodates a bearing rotatably supporting a wheelset. The supporting member is provided at an upper portion of the axle box. The plate spring supports a car width direction end portion of the cross beam and extends in a car longitudinal direction, and the plate spring includes a car longitudinal direction end portion supported by the supporting member. The axle beam couples the axle box and the cross beam in the car longitudinal direction and is opposed to the plate spring in an upward/downward direction. An installation seat is provided at an upper surface of the axle beam and includes an installation surface on which a pushing-up device configured to push up a lower surface of the plate spring can be placed.
