Abstract: A gondola railway car comprising 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 longitudinal trough portion between the trucks and the flat bottom portions, the trough portion having side edges joined to the side panel bottom edges and extending beneath the center sill, and an end wall at each end of the trough extending to the adjacent flat bottom portion.

Abstract: An underframe arrangement for a railway vehicle and including a deep section center sill joined to a draft sill portion through use of a transition beam member. Both the transition beam member and the draft sill have overlapping flange portions in the area adjacent the car body bolster and center filler. Overlapping these flange portions increases the strength of the draft sill to transition sill connection to resist buff and draft forces by directing these longitudinal forces into the bottom web of the draft sill and transition sill and from there through the transition section and into the deep section center sill which is capable of absorbing and dissipating large longitudinal loads. The overlapping members also increase the strength of the center filler area to provide an improved bolster.
