An intermodal road/rail transportation system wherein the freight containers or road trailers are adapted for transportation on detachable rail trucks or bogies. The system includes various bogie constructions, locking devices and trailer constructions which obviate the disadvantages of the prior art by, among other things, absorbing and/or minimizing the various stresses applied to the system. In the rail mode, the system allows the sequential starting of rail cars, thereby reducing the force necessary to start a string of trailers.

A railroad bogie intended to be placed between the ends of two freight containers, said bogie including a rigid chassis having two ends mounted on railroad wheels, each of the two ends of the chassis having a support which includes a container support surface to accommodate an end of a freight container, said support including means to attach said container end to said support in a removable manner and each of said two supports being pivotally connected to the chassis such that said supports pivot about a point which is substantially coplanar with the container support surface; wherein the supports each comprise a lower bolster perpendicular to the longitudinal axis of the chassis and attached thereto, and an upper bolster intended to accommodate an end of a freight container, with the upper bolster having in its center a support surface in the shape of a sphere segment resting on a support surface having a complementary spherical shape to constitute a pivot with a substantially vertical axis; and wherein the sphere segment of the upper bolster rests on the lower bolster via two surfaces making possible a predetermined sliding between them along the longitudinal axis of the chassis.
