수도권 광역철도 급행열차 운행방안 연구 - 경원선.중앙선을 중심으로 -

The operation of express train on the Seoul Metropolitan Subway Network is centered on the Kyungbu and Kyungin lines and the short section between Dongducheon station and Ganyung station which is 20.7km long. It is true that the needs of many customers who want to reduce their commuting hours by express train is not satisfied. This paper proposes that the operation of express trains be enlarged to Sungbuk station on Kyungwon line which comes to 34.9 km long, and to Yangsu station from Youngsan station on Jungang line. The type of operation is mixed one with high and low speed trains, which operates express train by use of existing siding tracks without improving facilities such as extra building of sidings. This pragmatic study is to apply the goal of reducing running time as express train and to suggest the selection of appropriate stops, effectivenes analysis of express train operation and formation of train diagrams to actual operation.
