Transloading, also known as cross-docking, is the process of transferring a shipment from one mode of transportation to another. It is most commonly employed when one mode cannot be used for the entire trip, such as when goods must be shipped internationally from one inland point to another. Such a trip might require transport by truck to an airport, then by airplane overseas, and then by another truck to its destination; or it might involve bulk material (such as coal) loaded to rail at the mine and then transferred to a ship at a port. Transloading is also required at railroad break-of-gauge points, since the equipment can not pass from one track to another unless bogies are exchanged.

Since transloading requires handling of the goods, it causes a higher risk of damage. Therefore, transloading facilities are designed with the intent of minimizing handling. Due to differing capacities of the different modes, the facilities typically require some storage facility, such as warehouses or rail yards. For bulk goods, specialized material handling and storage are typically provided (as, for example, in grain elevators). Intermodal transport limits handling by using standardized containers, which are handled as units and which also serve for storage if needed.
