A cushioning device includes a first housing with a first wall, a first extremity, a first open end and a first hollow interior. A second housing includes a second wall, a second extremity, a second open end and a second hollow interior, the second hollow interior sized to receive the first wall therewithin. A spring is disposed within each of the first and second hollow interiors between the first extremity and the second extremity. The first and the second housings are designed for a reciprocal linear movement relative to each other between a first position where the first open end being disposed at a distance from the second extremity and a second position where the first open end being disposed in a direct contact with the second extremity. The cushioning device may be installed within a sill of a railcar to cushion buff or draft forces from a coupler.

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.
