The present invention comprises an elongated container which may be carried either by rail or on a highway by a conventional truck tractor. The container includes a pair of dolly engaging pins fixed to its floor at the opposite ends thereof. The pins are adapted to engage a fifth wheel mechanism mounted on a dolly having wheels thereon adapted to engage conventional railroad rails. The dolly includes two fifth wheel mechanisms, one for receiving the pin from one container and the other for receiving the pin from another container. Also mounted on the undersurface of the container is a fifth wheel carriage which is adapted to slide longitudinally with respect to the container and which is adapted to engage the fifth wheel mechanism of a conventional truck tractor. A pair of truck wheels are mounted on a carriage which can be mounted to the rear end of the container for use on a highway when being pulled by a truck tractor.
