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.

A device for transporting freight articles in a ground or rail haul operations comprises a hollow housing including four corner sections, side walls, two center sections defining four openings each disposed between one edge of a center section and an edge of a respective corner section, a bottom portion and a top portion, wherein the two center portions are manufactured from see through or clear material. A door is mounted to selectively open and close a respective opening and swinging outwardly and towards a respective corner portion to selectively open the respective opening. Two channels are provided in the bottom portion, each in open communication with opposite sides of the bottom portion. Four feet or wheels are mounted on the bottom portion. Four receptacles are provided in the top portion, each sized and shaped to receive a foot therewithin.

A truck assembly for a rail vehicle includes at least one side frame including at least one lightener hole. At least one strain gage is disposed within the lightener hole(s). The strain gage(s) is configured to detect forces exerted into or onto the truck assembly. A method of detecting forces exerted into or onto a truck assembly of a rail vehicle includes disposing at least one strain gage within at least one lightener hole of at least one side frame of a truck assembly of the rail vehicle, and detecting the forces by the strain gage(s).

A railroad car truck including a first side frame, a second side frame, a bolster, and a plurality of warp restraints that are configured to prevent warping of the bolster relative to the side frames.

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.

A railroad car truck including a first side frame, a second side frame, a bolster, and a first plurality of warp restraints, each first warp restraint configured to prevent warping of the bolster relative to the side frames. Various embodiments include opposing bearings of each warp restraint that engage each other.

A chassis for a rail vehicle includes a chassis frame supported on at least first and second wheelsets and one A-frame linkage per wheelset on both sides of the chassis for horizontal axle guidance of the wheelset. Each A-frame linkage is connected in an articulated manner to one of two axle bearings of a wheelset by a wheelset-side bearing and to the chassis frame by two frame-side bearings. At least one of the bearings per A-frame linkage has a hydraulic bushing with variable longitudinal rigidity. The hydraulic bushing has at least one fluid chamber fillable with hydraulic fluid so that in the fluid chamber a hydraulic pressure can form for adjusting longitudinal rigidity. An acceleration sensor per axle bearing measures wheelset acceleration and an adjustment device adjusts hydraulic pressure in at least one of the fluid chambers depending on the measured wheelset acceleration.
