 Thus, intermodal facilities have specialized cranes for handling the containers, and coal piers have car dumpers, loaders, conveyors, and other equipment for unloading and loading railroad cars and ships quickly and with a minimum of personnel.Often the equipment used to ship the goods is optimized for rapid transfer.For instance, the shipment of automobiles is expedited by autorack rail cars and roll-on/roll-off ships, which can be loaded without cranes or other equipment.
