A more thorough explanation:

Intermodal transport, also known as multimodal shipping, is the transportation of goods using multiple modes of transportation and often involves more than one carrier. For instance, a shipment may be transported by air or sea, and then transferred to a truck or train for delivery to its final destination.

For example, a company may ship a product from China to the United States using a combination of air and sea transport. The product would be loaded onto a cargo plane and flown to a port, where it would be transferred to a cargo ship for the ocean portion of the journey. Once the ship arrives at a port in the United States, the product would be transferred to a truck or train for delivery to its final destination.

Another example of intermodal transport is the transportation of goods from a warehouse to a retail store. The goods may be transported by truck to a rail yard, where they are loaded onto a train for the long-distance portion of the journey. Once the train arrives at a rail yard near the retail store, the goods are transferred to a truck for the final delivery.

Intermodal transport is an efficient and cost-effective way to transport goods over long distances. It allows companies to take advantage of the strengths of different modes of transportation and can help reduce transportation costs and improve delivery times.
