A Study on the Scheme of Linking Jining-Datong Railway with Datong Railway Hub

Jining-Datong Railway is an important part of Huhhot-Nanning Railway corridor in the national “Eight North-South and Eight East-West” high-speed railway. Linking to Datong railway hub has a major in fluence on the overall alignment of Jining-Datong Railway and the general layout of Datong Railway Hub.Based on the analysis of the general situation of Jining-Datong Railway and Datong Railway Hub, combining with the forecast of passenger volume and passenger flow characteristics of the hub, three linking schemes are proposed according to the different factors, such as the route passing through the economic base, the general direction of the lines and the layout of the passenger stations in the hub. This paper makes a comprehensive comparison of the schemes and recommends the linking scheme of Xinrong on the east side, and analyzes the capacity of Datong South Railway Station. The capacity of the station meets the demand of the introduction capacity of Jining-Datong Railway.The research results meet the requirements of the overall trend of railway, conform to the urban master plan of Datong City and the master plan of Datong Railway Hub, and they also can effectively exert the capacity of the network points and lines.
