In order to provide sufficient and efficient service, rail freight station should be restructured or reallocated to the areas with more freight volume and are in the strategic locations. The possibility to extent potential stations into regional distribution center and transport hub should also be considered (Hesse 2004). Overall, this will contribute to reduce operational cost, resulting in improving efficiency of rail transport service as a whole. To achieve this, it is important to formulate a better integration of freight transportation service between railway and other transportation modes such as integration between rail and truck and integration between waterway and rail. This swift mode transfers are the key to successful intermodal operation, which lead to the higher potential of becoming the center of GMS distribution
center (Regan and Golob 2000).
