The electric vehicle can include: a payload interface, a payload suspension, a chassis, a set of bumpers, a sensor suite, a controller, a chassis suspension, and an electric powertrain. The electric vehicle 100 can optionally include a payload adapter, a power source, a cooling subsystem, and/or any other suitable components. The electric vehicle functions to structurally support a payload, such as a cargo container (e.g., intermodal container, ISO container, etc.), and/or to facilitate transportation of a payload via railway infrastructure.

A bogie frame includes a cross beam extending in a car width direction and including a car width direction middle portion at which a center pin arrangement space is formed. The cross beam includes a pair of pipe members extending in the car width direction and lined up so as to be located away from each other in a car longitudinal direction, and air spring seats provided at upper surfaces of car width direction end portions of the pair of pipe members. At least one of the pair of pipe members includes a curved portion at a car width direction middle portion thereof, the curved portion projecting outward in the car longitudinal direction such that a clearance between the pair of pipe members increases. The center pin arrangement space is formed between the pair of pipe members by the curved portion.

A bogie of a rail vehicle includes a frame, which includes two box-shaped longitudinal beam main bodies and a transverse beam main body; a wheelset, which includes an axle box, an axle and wheels mounted at two ends of the axle; a drive system, which at least includes a gearbox and a drive motor. Practice has proved that the two axle boxes arranged on the inner sides of the two longitudinal beam main bodies can reduce a volume by about 10%, and reduce a weight by about 10% to 15%, which can further reduce air resistance, and realize energy saving and emission reduction. The longitudinal beam main body is located on an inner side of a wheel, a span of the two the longitudinal beam main bodies is reduced, and the torsional rigidity of the frame is reduced, which is beneficial to improving a curve passing capacity.
