ABSTRACT:
The railcar includes two car units interconnected by a drawbar. The drawbar and conventional outboard end couplers are mounted at the locations spaced apart along the longitudinal center lines of the car units. Each car unit is made up of a gondola carbody and two single axle trucks which support the carbody at four vertical load support points. Each carbody includes a depressed center section and a through sill which extends between the drawbar and the coupler within the center section for transmitting buff and draft forces along a rectilinear load path which coincides with the longitudinal center line of the car unit. Essentially all vertical loads imposed on the center section are transmitted to and borne by the side walls. The railcar may be of nonarticulated construction, but in either case is particularly suited for fabrication from aluminum.
