Abstract
Novel highway trailers can be mounted on railtruck assemblies to form a train of highway trailers, the railtruck assemblies including a conventional railtruck which supports a novel intermodal adaptor. The novel highway trailers include a forwardly extending tongue and coupling structure at the rear to which may be secured to the tongue of a following trailer and the intermodal adaptor of a railtruck assembly. The intermodal adaptor is mounted on the center plate bowl of the bolster of the railtruck. The adaptor includes locating means adapted to be received within the coupling structure of a leading highway trailer, which locating means permits the leading highway trailer and intermodal adaptor to become aligned with each other upon relative movement. The intermodal adaptor further includes securing means capable of maintaining the locating means within the coupling structure of the highway, trailer in a completely mounted position, a coupler pin, and shifting means capable of moving the coupler pin from a lower position to a raised position where it couples the forward end of a tongue of a following trailer to the rear of the leading trailer and the intermodal adaptor.
