Abstract: The railcar includes a low profile skeletal frame having a depressed midsection with supporting surfaces extending therefrom and a four point truck suspension. Vertical loads are applied to the frame so that opposed bending moments are established with respect to one or both pairs of suspension load support points. The railcar is capable of transporting conventional trailers, semi-trailers or containers through existing tunnel clearances.

Abstract: A gondola railway car having a car truck attached to each end of a continuous center sill, a pair of generally vertical end panels, a pair of generally vertical side panels joined to the end panels, a plurality of cross bearers extending from the center sill to a longitudinal chord at the bottom of each side panel, a car bottom between the end and side panels having substantially flat portions over the trucks and a pair of longitudinal trough portions between the trucks and the flat bottom portions, each trough portion having a side edge joined to a side panel bottom edge and a side edge joined to the center sill, and an end wall at each end of each trough extending to the adjacent flat bottom portion.

Abstract: A vehicle decking bearer, by comparison with existing bearers, is better able to withstand the stresses due to normal work loadings, and is more easily incorporated in a vehicle structure, by reason of it consisting of a Z-sectioned longitudinal runner and a plurality of bolting stations by which it is U-bolted to the vehicle chassis. Each of the bolting stations comprises a bolt-hole able to receive the crotch of a U-bolt and located substantially in or near the neutral axis of the runner, and a bridge member secured to the runner so that a web portion of it, upon which the mentioned crotch rests, horizontally intersects said bolt-hole.
