Abstract
A railroad freight car including a cargo well for carrying optionally either intermodal cargo containers or highway semitrailers has a side sill structure including a deep rectangular top chord and a depending web, supporting a well floor structure. The well floor structure includes reinforcing longitudinal and transverse channel members and horizontal top and bottom plates attached to the channels. Large circular openings, aligned with one another, are defined in both the top and bottom plates, and a peripheral ring of vertical material interconnects the margins of the top and bottom plates around the openings. A reinforcing walkway structure is located atop each side sill at each end of the cargo well. In a multi-unit car adjacent car units are supported on a single shared wheeled truck. A trailer hitch is carried on a body bolster of one of the adjacent units to support the front end of trailer whose wheels rest on the floor of the cargo well of the other of the adjacent units, so that a trailer otherwise too long can be carried on the multi-unit car.
