Rail freight services offer international and domestic transportation via freight corridors. A freight corridor defines the railway lines across one country or crossing the territory of different countries.
An efficient international rail freight requires good interconnections between countries. There are many itineraries that international trains need to follow. This calls for a coherent coordination of the corridors managers to ensure a fluid transportation.
As a mode of domestic and international transportation, rail freight shipping is most often compared to road freight. It is also used as an alternative to it or used in combination with road freight, as intermodal rail freight.
