Abstract
A center stub sill railway tank car is disclosed having a generally cylindric, elongate tank. A center stub sill assembly is secured to the lower portion of the tank at each end thereof for transferring longitudinal train and lading loads between the tank and the center stub sill assembly. A bolster assembly is secured to the center stub sill and extends transversely of the car. An improved cradle assembly is secured to the lower end portion of the tank for reinforcing the tank bottom in the area of the center stub sill, the cradle assembly having an arcuate cradle extending at least in part circumferentially upwardly from the bottom centerline of the tank generally at the longitudinal position of the bolster assembly, and an upwardly facing hat section elongate cradle secured to the bottom end of the tank and extending inboard from the cradle. The center stub sill has vertical flanges extending inwardly from the bolster assembly on the outside of the hat section shaped cradle pad and welded thereto so as to transmit loading between the cradle pad and the center stub sill assembly.
