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. Each side sill has a height above the well floor, and a spacer is connected to the car body by an attachment which permits the spacer to be pivoted between a raised position clear of the well floor and a lowered position upwardly adjacent the well floor. The spacer has a predetermined height sufficient to support a trailer located in the cargo well, with its wheels resting on top of the spacer, high enough to locate lifting points on the trailer above the height of the side sill.
