A mounting interface for attaching supporting components to a buffer of a rail vehicle. The interface has a mounting body with a component fastening region and an attachment region that is different therefrom. The component fastening region is equipped with fastening elements and/or holes for attaching the components. The attachment region is formed in such a way that it can be fastened to at least two fastening points at the rear side of a buffer flange using buffer screws. There is also described a buffer system and a rail vehicle with such a mounting interface.

A railway vehicle includes a carbody frame which includes a roof, a bottom side opposed to and spaced apart from the roof, two opposite sides, a front end face, and a rear end face opposite to the front end face. The roof, the bottom side, the two opposite sides and the front and rear end faces delimit altogether an inner space. One or more posts are positioned at at least one of the front and rear end faces and extend, along a substantially vertical axis, for at least a portion of a vertical distance existing between the roof and the bottom side. One or more crushable devices are connected to and extend along the substantially vertical axis for at least a predominant portion of the vertical extension of an associated post of the one or more posts.

A collision energy absorbing device of a railcar includes: an outside plate constituting an outer tube including an axis extending in a car longitudinal direction; and at least one partition plate extending in the car longitudinal direction in an internal space surrounded by the outside plate, the at least one partition plate fixed to the outside plate and dividing the internal space. An outer shape of the outer tube is a shape that is symmetrical with respect to a virtual horizontal surface including the axis, and the at least one partition plate includes a missing portion in the internal space.

A rail vehicle car for transporting passengers comprising a car body, a car body floor, a car body ceiling and a front end area. An A-pillar is disposed in the front portion. The car body has a longitudinal extent and a transverse extent, and the longitudinal extent is greater than the transverse extent. The car body includes a height extension transverse to the longitudinal and transverse extensions. The A-pillar is substantially centered in the transverse direction so that the front region is divided into a first side and a second side, and the first side comprises 30-70% of the transverse extent.

A railcar that allows a first end beam to move toward a second end beam when an intended load is input is provided. A railcar includes a fuse member that couples a first end beam to a second end beam along a car longitudinal direction, and the fuse member buckles when a load received in collision exceeds a predetermined value to allow the first end beam to move toward the second end beam, thus ensuring reduction of variation of the load that allows the first end beam to move toward the second end beam. Consequently, when the intended load is input, the first end beam is allowed to move toward the second end beam.
