A quickly installable and removable integral lightweight floor structure trailer adaptor for railroad well cars for converting the well car from one for use with containers to one for carrying trailers, including a plurality of substantially equal height parallel disposed lightweight beams having substantially co-planer upper surfaces fixedly interconnected to form a rigid platform for the wheels of a trailer, the height of the beams being such as to raise the underside of a trailer to an elevation above the well car sidewalls a sufficient distance to provide withdrawal clearance for the loading arms of a trailer loading crane when the trailer with the adaptor carried thereby is loaded into the well car, and quick detachable coupling means securing the adaptor to the wheels of a trailer bogie with the tires seated on the adaptor to effectively restrain movement of the adaptor relative to the trailer wheels. The adaptor beams are of sufficient length to fit between and span the distance between the well car sidewalls and are of sufficient height to elevate a fully downwardly extended trailer landing gear above the normal floor plane of the well car when the trailer is seated in the well. Also provided are means for longitudinal and lateral positioning of the adaptor relative to the rear wheels of a trailer bogie.
