A railroad car body has a crossframe above and extending approximately the width of the car truck. The proximal side of the crossframe is pivotally attached to the car body for movement about a horizontal axis. At one end of the crossframe, at a spaced distance from the proximal side, is an upright strut extending between the crossframe and the truck. The upper and lower ends of the strut are connected respectively to the crossframe and the truck by ball and socket joints. At the other end of the crossframe, and at the same distance from the proximal side, is an upright double-acting hydraulic energy absorber connected, by ball and socket joints, at the top to the crossframe and at the bottom to the truck.
