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, providing a light but stiff floor structure with a small vertical height.
