A railroad boxcar has side wall assemblies that extend between the door frame posts to the end walls of the car. The side wall assemblies have an array of vertical stiffeners in the nature of tapered posts mounted on pitched spacing to the outside of the wall sheet assemblies between the door frames and the end walls. Lateral stiffeners, in the nature of stringers, can be mounted between the tapered vertical stiffeners. Alternatively, rigid deformations can be formed in the sidewall sheets themselves between the vertical stiffeners to provide local reinforcement to discourage local rippling and warping in the side wall sheets.
