Abstract

With a view to the commercialization of the Korean automatic variable-gauge bogie in the Eurasia railway system, the aim of this research was to perform an economic analysis concerning the possible introduction and operation of this bogie at the present time. For this purpose, we compared the possible types of freight connection service for container transportation, transshipment and the gauge-adjustable system, estimating the total life-cycle cost (LCC) incurred by each system, depending on type and quantity, over the whole process of acquisition, operation, maintenance and disposal. Based on this, we presented a case-by case analysis. Furthermore, in estimating economic feasibility, we analyzed the cost-benefit ratio taking into account not only the objective LCC, but also the reduced time required for the gauge-change and customer convenience. After estimating the LCC and analyzing the cost-benefit ratio of the respective systems, we demonstrated the economic superiority of view of the gauge adjustable system.

연구의 목적은 동북아 철도물류시스템에 한국형 궤간가변대차가 상용화되는 것을 가정하고, 향후 궤간 가변대차의 도입 및 운영에 필요한 경제성 분석을 목적으로 하였다. 이를 위해 향후 컨테이너 수송에서 예상되는 화물 연계 서비스 중 환적방식과 궤간가변방식의 서비스 유형에 대하여 경로별 그리고 수송량 별로 수송시스템의 획득, 운영 및 유지보수, 폐기의 전 과정 속에서 발생되는 총 수명주기비용을 예측하고 이를 기반으로 각 대안을 비교 분석하였다. 또한, 각 대안별 경제성을 추정하기 위하여 객관적 비용으로 나타나는 LCC 비용뿐만 아니라 서비스 유형의 차이로 발생하는 궤간변경 지점에서의 통행시간 절감부분과 부가적인 서비스 등 서비스 이용자의 직접적인 편익을 고려한 비용-편익 비를 분석하여 경제성을 추정하였다. LCC 분석 및 B/C 분석결과, 경제성 측면에서 환적방식에 비하여 궤간가변방식이 우수함을 확인하였다.
