A rail-based dry port (or inland port) has three basic requirements to fulfill a relevant commercial role; an intermodal terminal, logistics activities, and a corridor to a gateway. Economies of scale (massification of flows) and economies of agglomeration provide multiplying effects. Particularly, a high capacity and frequently serviced intermodal corridor coupled with an efficient rail terminal help reduce transportation costs while maintaining reliable services and therefore benefit the dry port’s customers, which are mostly logistics activities (distribution centers). The principle of co-location provides additional value to an inland port, particularly by minimizing drayage. It involves setting a real estate base that can be sold or leased to freight distribution activities.
