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.

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 bogie includes a chassis, including two beams, two crosspieces, two axle structures, each including two journal boxes, and a transverse axle shaft, extending in the transverse direction between two ends each supporting a respective wheel, the wheels defining an inner space between them, defined in the transverse direction between the wheels of a same axle shaft, and defined in the longitudinal direction between the two axle shafts, at least one motor supported by one of the crosspieces of the chassis, arranged in the inner space defined by the wheels, and including a coupling shaft, and at least one reducer. The bogie includes a primary suspension, including flexible mountings arranged between the crosspieces and the beams of the chassis, the reducer is arranged outside the inner space, the coupling shaft of the motor extending from the motor beyond one of the corresponding beams to the reducer.

The present disclosure relates to a maglev bogie, in particular to a maglev bogie with a centering function and a guiding method thereof. The maglev bogie comprises a maglev guide frame, crank arm brackets, guide wheels, first onboard magnet groups and cylindrical gears, wherein the crank arm brackets are hinged to the four corners of the top and bottom of the maglev bogie, the guide wheels are rotatably connected to the ends of the crank arm brackets, two first onboard magnet groups are slidably connected to each of the two inner sides of the upper part of the maglev guide frame, some of the cylindrical gears are connected to the top of the maglev guide frame where the upper crank arm brackets are hinged, two of the cylindrical gears are rotatably connected to each of the two sides of the top of the maglev guide frame, and every two adjacent cylindrical gears are meshed with each other. With the arrangement of the crank arm brackets, the guide wheels and the cylindrical gears, when the guide wheels on one side is squeezed by overhead track beam and displaced, the guide wheels on the other side can be synchronously driven to displace, so as to ensure a centered state of the maglev guide frame, the first onboard magnet groups, the overhead track beam and beam-borne magnetic track.

A coupler system includes: a coupler main body attached to a longitudinal direction end of a carbody of a railcar so as to be rotatable in a yaw direction; a curvature information acquiring portion configured to acquire curvature information of a track, the railcar being located on the track; a control portion configured to determine a target rotation angle of the coupler main body in accordance with the acquired curvature information and output a rotation signal regarding the determined target rotation angle; and a rotation angle changing portion configured to rotate the coupler main body to the target rotation angle based on the output rotation signal. When the railcar is stopped or when the railcar is traveling at a coupling speed, the control portion outputs the rotation signal to start rotating the coupler main body.
