既有复线区段快速列车越行站的布局研究

在分析列车运行图结构的基础上，深入研究了列车越行方式的产生条件，详细分析了既有复线区段开行快速列车而中间站配线数量不变时，对线路通过能力和列车旅行速度的影响，建立了快速列车越行站布局的概率模型。并以京广线和京沪线为背景进行了仿真分析，给出了我国既有复线快速列车越行站分布和站线配置的一般原则和结论。

An Investigation on Layout of Overtaking Stations for Express Trains along Existing Double Track Railways

Based on the analysis of the structure of train diagrams, the conditions for specific overtaking modes to take place are discussed. The carrying capacity and the speed of passenger trains are analyzed on condition that express trains are to be put into operation on the existing double track railways and the number of tracks in intermediate stations to be unchanged. A probability model for layout of overtaking stations for express trains is proposed. Simulation is conducted by taking the Beijing Shanghai and Beijing Guangzhou railways for example. Some principle for layout of overtaking stations for express trains along existing double track railways are suggested.
