According to some embodiments, a railcar comprises a first well component supported by a first railcar truck and a second railcar truck. The first well component is disposed between the first railcar truck and the second railcar truck. The length of the first well component is restricted to transport an intermodal shipping container no longer than twenty feet in length. In particular embodiments, the first well component is configured to transport a double stack of twenty-foot intermodal shipping containers. Each twenty-foot shipping container of the double stack may be loaded to maximum weight of 67,000 pounds. Particular embodiments include an articulated railcar with two or more twenty-foot well components.

A bearing for mounting an anti-roll bar on a bogie frame, the anti-roll bar extending along an axis transverse to the bogie and being mobile in rotation relatively to the frame around the axis, the bearing including a first half-shell, and a second half-shell adapted so as to be attached on the first half-shell by means of a first attachment system, the first half-shell and the second half-shell then forming a housing crossing through along the axis and adapted for receiving the anti-roll bar. The first half-shell is distinct from the frame and adapted so as to be attached on the frame by means of a second attachment system.

A bogie is capable of being moved from a rest configuration to an active configuration in which the bogie carries at least one vertical load. The bogie includes a chassis, at least one pair of wheels, and a shaft extending along an axle axis for each pair of wheels. Each wheel has a wheel hub extending along a hub axis and an axle box attached to the chassis and receiving the associated hub. Each hub is rotatable relative to the associated axle box. For each hub, the hub axis forms a non-zero camber angle with the axle axis of the associated shaft when the bogie is in the rest configuration.

A coupling includes a claw part and an intermediate piece. The intermediate piece includes a tube piece produced from aluminum or from an aluminum alloy, and a buffer part received in an end region of the tube piece and including elastic damping elements for receiving the claw part. The damping elements are surrounded by the end region radially at an outside in a circumferential direction. The buffer part includes a part which is different from the damping elements and is produced from a material of a brittleness which is greater than a brittleness of the tube piece.

A rail transport system includes a rail (10) provided with a first concave portion built thereon, and a rail vehicle comprising a bogie (21) and a vehicle body (22). The bogie (21) has a second concave portion (110) for straddling the rail (10), the bogie (21) movably straddles the rail (10), and the vehicle body (22) is connected to the bogie (21) and is pulled by the bogie (21) to run along the rail (10). The rail transport system according to embodiments of the present disclosure has the advantages of simple structure, low cost, small occupied space, and high stability.

A power train for an amphibian operable in land and marine modes includes a prime mover having an integral speed change transmission, at least a first land propulsion unit, at least a first marine propulsion unit, and a power transmission unit including a drive member configured to couple the prime mover to the at least first marine propulsion unit, wherein the prime mover is arranged to drive the at least first land propulsion unit through/via the integral speed change transmission in the land mode, and the prime mover is arranged to drive the at least first marine propulsion unit through/via the power transmission unit in both the marine mode and the land mode.

A traction mechanism, a bogie assembly and a straddle-type monorail vehicle are disclosed. The traction mechanism comprises: a traction component, comprising a transmission shaft and a traction connecting rod, the transmission shaft and the traction connecting rod being connected, the transmission shaft being suitable to be rotatably connected to a vehicle body, and the traction connecting rod being suitable to be hinged to a bogie frame; and a traction crank, both ends of the traction crank being suitable to be respectively hinged to the bogie frame and the vehicle body. The traction mechanism of the present disclosure has a simple and compact structure, and a transmission path of a traction force is short. The traction mechanism is convenient to assemble and disassemble, occupies a small space, is wide in usage range, can be used for low-floor and high-floor vehicles, and is also applicable to a single-axle bogie, a double-axle bogie and a multi-axle bogie.
