Apparatus for adapting well cars for trailer carrying use without degrading its double stacked container capability, including a trailer hitch head and mounting pedestal attached to the end deck of the well car for securing the trailer kingpin onto the car mounted hitch head, and a plurality of lightweight aluminum floor beams or panels which support the trailer bogies. The beams can be dropped into place on the car floor with locating pins providing the fore and aft positioning, and are sufficiently light that two men can lift and position them. In two forms the beams bridge between the lower side sills of the car and transfer the vertical load by bearing on the inward turned flange portion of the side sill, and in another form are partly supported by the car lower end plate. The floor beams structures add only approximately 500 to 600 pounds in weight, rather than the 5,000 pounds of a permanent type floor, and do not raise the trailer height above the normal double stacked container height. The floor beams height, on the order of one foot, permits the trailer to be loaded onto the well car with the trailer landing gear in fully downwardly extended position instead of having to retract the landing gear, which permits the trailer to be loaded and unloaded at siding in approximately half the time it takes to load and unload if the landing gear had to be raised and lowered. The height of the floor beams stops the vertical descent of the trailer at a point were there is adequate clearance for the crane loading arms to release the trailer after depositing it into the well car. Means for locking the beams assembly together is provided.
