Abstract: A bimodal container chassis for supporting a container during roadway and railway transit includes a mainframe having first and second ends, a top edge and a bottom angled edge. The bottom angled edge is positioned at an angle from horizontal. A running gear attachment is connected to the mainframe and slidable along the bottom angled edge in first and second directions between an over-the-road position and an over-the-rail position. The first direction is upward and toward the first end and the second direction is downward and toward the second end such that the running gear attachment is disposed adjacent the second end when in the over-the-road position and disposed upward relative to the over-the-road position and toward the first end when in the over-the-rail position.

Abstract: 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 connects 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 locks 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.

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 (26) 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 (28) by primary air springs (90). 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.

Abstract: The disclosure provides a bimodal container chassis of differing lengths in a gooseneck type as well as a flat beam type for supporting ISO and domestic containers and other cargo during highway as well as railway transit. The bimodal container chassis has a front end equipped with a king-pin for connecting to a tractor and a rear end equipped with braking and suspension components, axles, wheels and tires, which make the bimodal container chassis suitable for road transport. The bimodal container chassis has front and rear ends for connecting, and thereby suspending, the bimodal container chassis including but not limited to its payload between two rail bogies, which make the bimodal container chassis suitable for rail transit.
