1. With transferrable container units.
2. Container ships are unloaded at ports like Long Beach Calif. onto trains.The trains carry the containers to places like Illinois where they are unloaded onto trucks and taken to a holding facility.Then they are hauled for delivery to their final destination.Then the empty containers are returned to the railroad,loaded back on trains and the process is reversed.
3. The last two answers didn't answer the question....IE...TRUCKING companies....not container ships. Big companies like UPS, Schneider, Yellow, Roadway, and others put their trailers on railroad flatcars especially designed for trailers that in most cases do not handle containers, and definitely not double-stacks. Double-stacks are transported in well cars that have a section that is lower between the bogies so as to reduce height. Trailers are loaded on TTX flats or spine cars at one end, travel fairly long distances, then are unloaded and delivered by truck. It avoids extra truck drivers, traffic jams, and such, and is a lot cheaper. Norfolk Southern has a special service called Triple Crown that utilizes special reinforced trailers with detachable rail wheels and therefore do not have to be loaded on railroad cars at all. they have to be reinforced for buff forces. A normal highway trailer would be ripped apart by the weight of the trailing trailers.
