A gondola car for hauling bulk cargo has a stub sill for receiving longitudinal loads. A shear plate is connected with the stub sill, and longitudinal side sills and connected as by welding to side portions of the shear plate. Side walls extend upwardly from the side sills. The shear plate has an opening therein adjacent the longitudinally inward end of the weld to the side sill for reducing stress in the end of the weld. Cover structure overlies the opening, and side wall support structure is connected with the cover structure and engages the side walls to support them.
