ABSTRACT:
A rail road car has a deck for carrying wheeled vehicles. The rail road car can be coupled to other rail road cars of the same type. Bridge plates are provide that permit wheeled vehicles to be conducted between adjacent rail road cars. The bridge plates have one end mounted to the rail road car at a pivot fitting. The pivot fitting allows the bridge plate to be moved from a length-wise position spanning the gap between cars, to a cross-wise stowed position. The bridge plates have fittings which permit three degrees of freedom relative to the adjacent rail road cars, namely a first degree of freedom to tolerate yawing motion of the first rail road car, a second degree of freedom to accommodate yawing motion of the second rail road car, and a third degree of freedom to accommodate variation in distance between the respective portions of the rail road cars to which the bridge plate is mounted while the rail road cars are moving.
