<p>An intermodal system for moving highway semi-trailers by rail transportation. Trailers of any length are carried on a plurality of rail bogies (10) such that one end of the semi-trailer is carried by one rail bogie and the other end of the semi-trailer is carried by another rail bogie (10). Each rail bogie has a frame structure (12) supported on spaced-apart, wheeled axles. The frame structure defines a central drop deck section having a stationary, longitudinally extended, planar platform. Each rail bogie (10) further includes a trailer securement sytem. The trailer securement system includes a chock assembly (42) for facilitating trailer loading through simultaneous rotational movement of the semi-trailer's wheels through an arc on the platform (16) and translatory movement of the wheels along a predetermined longitudinal path on the platform. The chock assembly (42) includes a transversely spaced pair of joined chock blocks (48,50) normally arranged on one side of the semi-trailer's wheels. The present invention further presents a method for forming a consist comprising a highway semi-trailer supported between first and second rail bogies.</p> |
