Abstract Research purposes: Under the mode of express/local trains of urban express rail transit, the setting of overtaking stations affects the project investment, operation efficiency, and operation safety, which is one of the key problems in the planning and design of express/local train operation organizations. The number and operation proportion of express/local trains have an important impact on the setting of overtaking stations. This paper takes the operation organization design of express/local trains of Chongqing rail transit line 27 as an example, calculates and analyzes the influence of express/local train proportion on the line capacity, the number of overtaking stations, and the location of overtaking stations based on the overtaking station distribution calculation method. Suggestions are given for overtaking stations settings.
Research conclusions:(1) A smaller train proportion can better take into account the line capacity and the number of express/local trains. And a large train proportion can improve the line capacity, but the number of express trains will be lost. (2) The change of train proportion has little impact on the number of overtaking stations when the line capacity is certain. (3) By setting overtaking stations near the terminal stations, the line can better adapt to different operation ratios of express/local trains. (4) The research results can provide reference for the setting of overtaking stations and the design of the organization scheme of express/local trains in urban express rail transit.

Key words： regional rapid rail transit express/local train operation proportion overtaking station
