ABSTRACT:
A center sill-less type gondola railroad car having an aluminum car body which includes an extra large load carrying compartment or container supported on a surrounding horizontal rectangular framework that consists essentially of a pair of transversely oriented shear plates at opposing ends of the car body, and a pair of parallel side sills which extend longitudinally between the shear plates and which are attached to the shear plates by special load transfer members, each of which members consists of two pairs of legs which extend radially from a common central juncture and which are designed to withstand the high stresses that peak at the spots where the members first contact the shear plates. The car body has a pair of oppositely disposed, upwardly curving side walls and a U-shaped, downwardly curving bottom portion which coact with a pair of stepped end walls to form the container which has an open top in spaced vertical relation above a closed bottom. The bottom portion of the container is secured to downwardly extending legs of the two load transfer members in spaced relation below a pair of V-shaped crotches which are formed by the legs and in which the side sills are secured. The side walls are fastened to the side sills in spaced relation above the juncture of the legs of each of the load transfer members.
