摘　　要：市域铁路是适用于都市圈中心城市城区连接周边城镇组团的轨道交通系统,提供公交化、大运量、快速便捷的交通服务。为提高运输效率,市域铁路要求列控系统满足3 min追踪间隔,而站后折返间隔成为缩短追踪间隔、提高运输效率的最大障碍。应用于莞惠城际的CTCS2+ATO列控系统虽然具备半自动折返功能,但无法满足市域3 min的站后自动折返间隔要求。CTCS2+ATO列控系统应增加自动折返功能,以满足市域铁路需求。建议车载ATP实现快速换端、快速启机,减少换端过程耗时;建议车载ATO实现快速发车、快速运行、快速停车,减少运行过程耗时;建议CTC实现自动办理折入进路、自动办理折出进路,减少进路办理耗时;建议为不同编组列车设置不同的停车点,提升不同编组列车的折返效率;建议优化折返站的车站股道有效长和车站咽喉区长度,尽量减小折返进路长度,提升折返效率。通过以上改进措施,经过实验室验证,可以满足市域铁路的3 min折返间隔要求。The suburban railway is a rail transit system suitable for connecting the central city of metropolitan area with the surrounding towns,and provides public transportation,large capacity,fast and convenient transportation services.In order to improve the transportation efficiency,the train control system is required to satisfy the 3 minute tracking interval,and the back-turn interval becomes the biggest obstacle to shorten the tracking interval and improve the transportation efficiency.The CTCS2+ATO train control system applied in the Dongguan-Huizhou Intercity Railway has semi-automatic turn-back function,but it can not meet the requirement of the automatic turn-back interval after station for 3 minutes.CTCS2+ATO train control system should be added automatic turn back function,which can meet the needs of urban railways.It is suggested that on-board ATP can realize quick end change and quick start of mission to reduce the time consumption in end change process.It is suggested that on-board ATO can realize fast departure,fast operation and fast stop to reduce running time.It is suggested that CTC can automatically handle the turn in route and turn out route to reduce the time consuming for route handling.It is suggested to set different parking points for different marshalling trains to improve turn back efficiency of trains with different lengths,and to optimize the effective length of the station track and the length of the station throat area of the turn back station,minimize the length of the turn back route,and improve the turn back efficiency.Through the above improvement measures and laboratory verification,the 3 minute turn back interval requirements of municipal railways can be met.
