철도물류 활성화를 위한 철도정거장 개량 연구: 피기백(PIGGY BACK)시스템 도입을 중심으로

There is no question that railroad investment is crucial for better transport systems and the Korean governmenthas continued to invest in railroad facilities. Nevertheless, the modal share of railroad, in particular, for freight hasdecreased. This is because rail freight transport can hardly meet customer needs such as just-in-time(JIT), adoor-to-door service, compared to road transport, to be specific, trucking which can directly carry the freights tothe final destinations. This has made the value of the railroad infrastructure less, which has been operated for thepast 114 years. This study proposes a new freight movement concept called Piggy Back System. This system cancarry freight trucks on the trains and deliver the freights to the final destinations. It can make a door-to-doordeliver system possible for railroad transportation, which is the key factor for modal shift from road to railroad.
For implementing this, this study proposes three important things: the cost-efficient reforming way of railroad yardthat has been used for the past 114 years, the diagram plan of train services, and some technical reviews likeclearance limits. This is the first study with practical proposals and solutions on this topic in Korea. Thesuggestions of this study cut down distribution costs by more than seven trillion won.
