A carbody of a railcar includes: an underframe; a first member provided at one of vertical sides of a vertical center of the underframe, supported by the underframe, and absorbing collision energy; a second member provided at the other vertical side of the vertical center of the underframe, supported by the underframe, and contacting an obstacle when the first member is compressed by collision with the obstacle. In a case where the second member receives a reaction force from the obstacle when the first member is compressed by the collision with the obstacle, the second member transfers to the underframe a moment load that is opposite in a rotational direction to a moment load transferred to the underframe by the first member.

A railway vehicle and a head car cowcatcher thereof are provided. The head car cowcatcher includes a flow guiding plate; a front-end frame mounted at a front end of an inner side surface of the flow guiding plate; and longitudinal sills mounted at two sides of the inner side surface of the flow guiding plate. Two ends of the front-end frame are respectively connected to the longitudinal sills located at the two sides. The rigidity of a connecting part of the longitudinal sills and the front-end frame is smaller than the rigidities of any parts of the longitudinal sills and the front-end frame. When obstructions are cleared or a train collision occurs, the connecting part of the front-end frame and each of the longitudinal sills would be largely deformed if the impact force the cowcatcher bears is beyond the maximum load the cowcatcher can bear.

Anti-climbing device for a rail vehicle includes a baffle plate, wherein a plurality of mutually parallel protruding first formations are arranged along a linear path on the baffle plate, and a plurality of mutually parallel protruding second formations are arranged along a linear path on the baffle plate and are orientated normally with respect to the first formations, where the extent of the second formations over the face of the baffle plate is smaller than the extent of the first formations over the face of the baffle plate, and where the first formations, at intersection locations of the formations, each have a recess in which the extent of the first formation is reduced.

An anti-climber device for a rail vehicle includes an impact plate having a plurality of protruding formations, wherein the profile of the formations when the anti-climber device is in the installed position is formed as a polygonal curve with a repeating sequence of sections that rise and fall relative to the horizontal, where the extent of the formations above the surface of the impact plate follows a polygonal curve with a repeating sequence of rising and falling sections.

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.
