Abstract: An intermodal road/rail transportation system wherein the freight containers or road trailers are adapted for transportation on detachable rail trucks or bogies. The system includes various bogie constructions, locking devices and trailer constructions which obviate the disadvantages of the prior art by, among other things, absorbing and/or minimizing the various stresses applied to the system. In the rail mode, the system allows the sequential starting of rail cars, thereby reducing the force necessary to start a string of trailers. The system also includes a variety of compatibility components to allow use of the system with other dissimilar intermodal or bimodal systems and/or conventional locomotives and freight containers.

Abstract: Two containers are mounted on telescoping chassis sections and moved toward each other. Mating coupler structure at juxtaposed lower corners of the containers rigidly connect the containers horizontally. At least one spacer member at the juxtaposed upper ends of the containers space the containers from each other. Cables connected to the ends of the coupled containers may be utilized to lift the containers as a unit off the chassis sections for loading into a container ship.

Abstract: The housing of a wheeled trailer has a discrete bottom rail-scuff plate along the bottom end of each side wall. Each scuff plate is coupled to the bottom wall of the housing and extends upwardly from the floor surface for a height of at least eight inches. The upper end portion of each scuff plate supports the lower ends of inner and outer panels of the side wall whereby the inner surface of the bottom rail acts as a scuff plate to protect the inner panels from being scuffed by the load or lift trucks for handling the load.

Abstract: A trailer container or the like has a rear header that extends upwardly and rearwardly from the roof. The roof is supported by a horizontally disposed flange at or adjacent to the bottom surface of the rear header so that the vertical height from the container floor to the rear header bottom surface is substantially the same as the height from said floor to said roof.
