5. CONCLUDING REMARKS
Due to the prioritized government policy, investment has been given to road construction rather than to railway network. Thus, railway infrastructure is inevitably deteriorated by limited investment and maintenance. Railway transportation mode cannot increase freight services both because of the limitation of special wagons for bulky merchandises and the limitation of number of service stations and coverage. The expansion of rail freight services thus are constrained and discouraged. Inadequate integration with off-rail transport service also disturbed the development of new freight services.
