Multimodal transport is a generic term for the transport of goods, but also for the transport of passengers, in which two or more modes of transport are used. Intermodal transport is limited to the transport of goods in freight transport. The term intermodal transport is used worldwide. It means that goods are transported in the same loading unit or road vehicle by two or more modes of transport. The loading unit changes the mode of transport. The goods to be transported remain in the same loading unit. Combined transport is a sub-concept of intermodal transport in Europe, in which the main part of the journey is made by rail, inland waterway or sea, and the pre- and post-carriage by road is kept as short as possible. Beyond the conceptual differences, the aim is to get the best out of the individual modes of transport and to combine their advantages. TRAINMILE combines the flexibility and range of road transport with the efficiency, safety and sustainability of rail.
