The skirts provide an extended bearing area upon against which bundled loads can be secured. The skirts are inwardly reinforced to discourage deflection between adjacent upright members of the deep upper beam structure.

An autorack railroad car has an underframe that, in contrast to the prior art, has a straight-through center sill that is shallower, and of diminished geometry-based sectional properties generally, in the middle portion between the trucks than at the end portions at either the draft sills at the draft gear or at the truck centers. The bottom flange of the center sill is carried at a constant height from end to end, and is free of kinks in elevation. In the mid-span portion of the car, from truck center to truck center, the center sill is shallower in section than the side sills. The bottom flange of the center sill is carried at a height that corresponds to, or is higher than, the height of the lower flanges of the side sills, such that the cross-bearer arms are shallow, and the bottom flanges of the cross-bearer arms are substantially level.

This invention is a guided transport vehicle with berth with open side and bottom for a roadway vehicle to be driven along side on a station driveway and obliquely steered into the berth and lifted for transport on the transport vehicle and lowered to another station driveway and obliquely steered out from the berth.

A center beam car has a main deck structure extending laterally from a main center sill, a laterally extending top truss structure, and a central vertically oriented central beam structure. The center beam so formed defines bunks in which to carry cargo. The upper region of the web-work structure includes a top chord mounted to run between two end bulkheads. The deck has a central portion and end portions. The end portions of the deck are carried at a greater height than the center portion, the difference in height corresponding to the height of a bundle of lumber. The car has a center sill having a depth corresponding to the depth of the step in the deck. The end portion of the center sill has an internal plate defining a draft gear pocket upper wall. The medial portion of the center sill is narrower than the end portion, and of deep section, such that it has a high aspect ratio. Web separators are mounted in the medial portion of the center sill by a method that includes making part of the weld from outside the center sill through welding apertures. As the end deck is carried at a high level, the bolster is abnormally deep.
