The pusher structure is returned to the front end of the container after the dumping operation. The conveyance is adapted to be a flatbed truck trailer having tracks thereon receptive of bottom rollers on the container, whereby the container is adapted to be brought adjacent to a dump site on a railroad flatcar, transferred to the trailer, taken to the dump site, the pusher structure operated to unload the container, and the container then returned to the railroad car.
