The term intermodality first appeared in freight transport in the 1960s in the USA, in the context of the introduction of standardized containers. Such standardized containers can be transported by rail, by truck, by ship. Intermodal freight transport describes a kind of freight shipping in which a transport or loading unit is transported using two or more modes of transport. It should be noted that the principle only involves a change of loading unit. There is no transshipment of the actual goods.
