Abstract
A railroad freight car with a lengthened container well, including an extended and reinforced well car unit side sill, and a method for lengthening a container well of a railroad freight car intended for carrying an intermodal cargo container. A side sill extension member is welded into position, between a body bolster at each end of the container well unit and a nearest container support assembly, and a container-well bottom assembly is lengthened at each end of the container well. A longitudinally-extending doubler plate may be welded to the longitudinally central portion of the side sill, to ensure sufficient rail clearance at mid-length of the car.
