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. 철도투자의 필요성은 누구나 공감하고 정부에서도 지속 투자를 시행하고 있으나 철도의 화물수송 분담률은 오히려 감소하고 있는 실정이다. 이는 다빈도, 신속, 신뢰성을 요구하는 즉시인도(Just In Time: JIT)와 문전수송 (Doorto Door) 등 고도화되는 고객의 욕구를 충족시키지 못하였기 때문이다. 결과적으로 지난 114년 동안 구축된 철도인프라 시설이 점점 효용가치를 잃어 가고 있다. 이에 본 연구에서는 철도수송의 근본적인 문제점인 문전수송(Door toDoor)을 해결하지 않고는 도로수송을 철도수송으로 전환하는 것은 어렵다고 보고 도로에서 철도로의 전환(ModalShift)이 가능하도록 철도수송 시 철도화물역에서 최종목적지로 환적없이 화물자동차를 직접 운반하는 피기백(PiggyBack)시스템이라는 신개념을 정립함으로써 문전수송(Door to Door)에 의한 철도화물 수송의 경쟁력 확보 및 활성화방안을 제시하고자 한다. 피기백(Piggy Back)시스템 적용방안으로는 짧은 기간 내에 적은 투자비로 즉각 시행이 가능하도록 지난 114년 동안 구축된 기존 철도인프라를 활용하는 정거장 배선계획을 제시하고, 이에 따른 세부 열차운행방안 및 피기백시스템 도입시 건축한계 등 기술적인 검토를 시행함으로써 연간 국가 물류비를 약7조원이상 절감할 수 있는 획기적인 방안을 우리나라 최초로 제시하였다.

Determining the investment priority of the railway project is essential to keep its object of railway investment. [National railway construction plan] provide 4 major evaluation indicators and their weighting range in determining the investment priority of railway construction. Which are investment efficiency, inter-regional balance of development, network effects, government supporting policy. However this present criteria has inconsistency in determining economical feasibility of the railway transportation when applying the same evaluation indicator, investment efficiency, with the road transportation. The railway transportation is superior to road transportation in terms of transportation capacity and distance, while offering less carbon emissions. In spite of the prominent position of the railway transportation, it can be failed to obtain its proper investment priority when being determined under economical feasibility based. Therefore, this study analyzed the inconsistency under present evaluation criteria and proposed new evaluation method for the investment priority of the railway construction using AHP(analytic hierarchy process), while differentiate from the road construction. This method is optimized for only determining the priority of the railway construction itself under object of railway investment respectively.
