In 2022,the coal production in Yulin,northern Shaanxi,reached 584 million tons,including 300 million tons transported via railways.The long-term railway coal freight volume is predicted to increase to 480 million tons,including 260 million tons destined for eastern regions.The region heavily relies on the Baotou-Xi'an Railway,which connects lateral railways such as Taiyuan-Zhongwei-Yinchuan,Huangling-Hancheng-Houma,Lanzhou-Lianyungang,and Baotou-Lanzhou lines for coal transportation.However,due to the saturated capacity on the Yulin-Suide section of the Baotou-Xi'an Railway and the near-saturated capacity on the subsequent route of the Taiyuan-Zhongwei-Yinchuan Railway(Shijiazhuang-Taiyuan section),these existing routes cannot meet the growing demand for further eastward coal transportation in the region.Therefore,this paper proposed a new transportation route for eastward coal transportation in northern Shaanxi.The research compared two schemes from the perspectives of project investment,channel scale,operation management,transportation organization,channel layout,and economic stimulation along the route:first,expanding the capacity on the existing route from Shenmuxi to Watang,and second,building a new Yulin-Jiaxian-Linxian route.Expanding the capacity along the existing Western Shenmu-Watang route optimizes the utilization of the existing railway infrastructure and surplus transportation capabilities.This approach involves a smaller engineering scale,serves more coal mines along the route,and maximizes the overall efficiency of the rail network;and it establishes a direct and smooth route for eastward Shaanxi coal transportation,which addresses the insufficient transportation capacity while relieving the capacity on the bottleneck section of the Baotou-Xi'an line,supporting southbound coal transportation from Shaanxi.
