Abstract
A car coupling system for a rail vehicle includes a draft sill, and a crash energy management system disposed within the draft sill. The crash energy management system includes a first end plate, a second end plate, and a central tube disposed between the first end plate and the second end plate. The central tube is configured to deform in response to a force exerted into the car coupling system that exceeds a predetermined force threshold. Deformation of the central tube attenuates at least a portion of the force.
