摘　　要：市域(郊)铁路主要布局在经济发达、人口聚集的中心城市,联通城区与郊区及周边城镇组团,主要满足通勤客流需求,高峰时段需要提供公交化运营服务。通过阐述大站快车概念及产品定位,分析市域(郊)铁路开行大站快车的必要性,剖析列车高峰小时能力构成要素,研究考虑采用CTCS-2+ATO+自动折返列控技术,基本可以实现20对/h的折返能力,在此基础上,结合客流特征,确定大站快车的开行方案。在采用快慢车共线运输组织模式下,通过铺画高峰小时运行图,分析车站具备越行条件和不具备越行条件2种方案,在保证大站快车均衡铺画的前提下,研究能力范围内大站快车可开行的最大对数。以北京枢纽东北环市郊铁路为例,对研究成果进行验证,为研究市域(郊)铁路开行大站快车提供参考。The suburban railway is mainly located in the central cities with developed economies and concentrated populations.It connects the urban area with the suburbs and surrounding towns,mainly responsible for facilitating the commuter flow and providing public transportation operation service during rush hours.By expounding on the concept and product positioning of express trains in major stations,the necessity of operating express trains in major stations along suburban railways was analyzed.According to the analysis of the components of the rush hour capacity of the railways,the CTCS-2+ATO+automatic reentry train control technology was considered,which could basically realize the reentry capacity of 20 pairs/hour.On this basis,the characteristics of passenger flow were analyzed,and the operation scheme of express trains in major stations was determined.By adopting the co-line transportation organization mode of express and slow trains and laying out the rush hour operation diagram,this paper analyzed the two schemes of the station with and without overtaking conditions and studied the maximum pairs of express trains operated in major stations on the premise of ensuring the balanced layout of express trains in major stations.The results of the study were verified by taking Beijing’s northeast-ring suburban railway as an example,which provided a reference for studying the operation of express trains in major stations along suburban railways.
