Intermodal shipping refers to transporting freight using two or more modes of transportation, typically involving trucks, trains, and/or ships, without any handling of the freight itself when changing modes. The key benefit of intermodal shipping is that it takes advantage of the strengths of different transportation modes, typically resulting in cost savings, environmental benefits, and efficient long-distance freight transport. The most common form of intermodal transportation is using truck-rail-truck routes, where cargo is picked up by a truck, transported long distances by rail, and then delivered to its final destination by another truck.
