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 coupling pin is operated up and down by either manual or air operated actuators, and is locked in the up position by a manually operated safety latch. The upper frame is supported from dual steerable lower frames by primary air springs so that when the springs are deflated, the upper frame is lowered to allow the trailers to be pushed upon the load carrying surface. When the air springs are inflated, the trailers are raised so that the trailer wheels are carried above the railroad track. 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. An alternate automatic coupler as a substitute for the above described coupling scheme is also shown.
