A rail-based dry port (or inland port) has three basic requirements to fulfill a relevant commercial role: an intermodal terminal, the presence of logistics activities, and a corridor to a gateway that offers connectivity to external markets. 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 helps reduce transportation costs while maintaining reliable services and, therefore, benefits logistics activities (distribution centers). The principle of co-location provides additional value to an inland port, particularly by minimizing drayage. It involves setting up a real estate base that can be sold or leased to freight distribution activities.
