Intermodal transportation refers to the movement of goods using multiple modes of transportation, such as by truck and train or by ship and truck. This allows for the efficient and cost-effective transportation of goods over long distances. Intermodal transportation is often used in supply chain management and logistics to move goods from the point of production to the point of consumption. It can also be used to transport goods between different modes of transportation, such as from a ship to a truck at a port.
