Abstract Research purposes：The Chongqing - Guizhou railway is a line for the mixed passenger and freight traffic, and is an important part of the convenient，rapid，large capacity channel from the Sichuan，Chongqing and the northwest area to the Guizhou, Guangxi, Hainan, Guangdong areas. The line needs to access into the Guiyang hub in the northern city and the passenger train of the railway accesses into the Guiyang Bei Station. But where does the freight train access into the Guiyang hub is the urgent problem to be solved because it relates to the disturbance level to the city planing and the construction investment. This paper compares and analyzes the two optional plans of accessing the freight train into the Dulaying Station via connecting line and accessing the fright train into the existing Sichuang - Guiyang Railway via connecting line to determine the more reasonable plan.
Research conclusions：From the analysis of the line direction of the Chongqing - Guiyang Railway after it accessing into the Guiyang hub，it is concluded ： ( 1) The plan for the freight train of the Chongqing - Guiyang Railway accessing into the Guiyang hub should consider the demands of the upgrading of the existing railway line to reduce the abandon projects in long — term future. (2) The plan for the fright train accessing into the existing Sichuang - Guiyang Railway via connecting line can save the construction investment and has a good coordinations with the projects in the near future and long - term future. (3) This research can provide the reference to the similar works.
