Abstract
Refinements and improvements in intermodal rail vehicles for making up a train of highway trailers are shown. The improved intermodal vehicle has a one-piece upper frame assembly () with a horizontal load carrying surface below the ends of a drawbar for connecting the trailers. Each highway trailer has a coupler socket assembly at both its front and rear into which the drawbar enters and is connected to the intermodal vehicle by a vertical coupling pin projecting upward from the horizontal load carrying surface. The upper frame is supported from dual steerable lower frames () by primary air springs (). A backup suspension system is provided so as to support the upper frame in the event of failure of the primary air springs. A transition rail vehicle for adapting the unit train of trailers is provided, incorporating the necessary features of the intermediate intermodal vehicles heretofore described.
