城市轨道交通既有线路有效提升运营服务品质的途径相对较少，既有线路开行快慢车作为一种大胆尝试和创新突破，在高质量发展的背景下，具有非常广泛的应用需求。针对既有线路开行快慢车的方法进行系统梳理，根据不同线路特点和运营需求，提出既有线路开行快慢车的 4 种方法，分别是利用大的行车间隔开行快车、利用交替式跨站停车开行快车、利用故障停车线开行快慢车、利用小交路折返开行快慢车。结合国内外应用实例，对各种方法的开行原理、优缺点以及运营要求等进行详细分析，并介绍既有线路开行快慢车需要改造的内容

Current solutions for enhancing the efficiency of existing urban rail transit lines are limited. As a pioneering initiative,the concept of running express/local trains on these lines presents a versatile solution for Shigh-quality development scenarios.After systematically reviewing the methods for running express/local trains on existing lines, this paper introduces four distinctstrategies tailored to the unique features and operational needs of different lines: employing extended intervals for rapid trains,implementing alternate station-skipping for accelerated service, utilizing malfunctioned train stop lines for express/local runs,and operating partial-route shuttles for express/local trains. Drawing from domestic and international case studies, this researchdelves into the operating principles, advantages, disadvantages, and operational requirements of the aforementioned methods.Additionally, the necessary modifications for implementing express/local train services on existing lines are discussed.
