-1- Abstract: An underframe construction for rolling stock comprises longitudinal side sills, end sills connecting the opposite longitudinal ends of one of the side sills to the corres- ponding opposite longitudinal ends of the other side sill, body bolsters respectively located at positions correspond- ing to trucks, and center sills extended between the end sills and the corresponding body bolsters parallel to the side sills. A floor member is fixed in the area defined by the side sills and the end sills, and comprises an upper plate, a lower plate and a corrugated plate disposed between the upper plate and the lower plate. The corrug- ated plate has an alternate arrangement of longitudinal ridges and furrows and is fixed to both the upper and lower plates. The floor member is a load bearing member substituting for the cross beams and keystone plate of a conventional underframe construction. The result is an underframe construction that has a floor member with a weight and thickness smaller than those of the conventional construction.
