The global COVID-19 pandemic is having a significant impact on the development of many aspects all over the world. As an important part of public services, rail transit requires effective response countermeasures to control the spread of COVID-19. Considering the current development of the epidemic situation, this article discusses the characteristics of COVID-19 transmission and identifies vulnerable areas to target in order to prevent and control the spread of the epidemic in the rail transit system. Countermeasures adopted to prevent the spread of COVID-19 are analyzed in terms of external and internal categories, which were classified into six groups: passenger service, case care, information, staff, equipment and operation management. An evaluation architecture was also constructed, which was established from the perspective of effectiveness, economic efficiency, acceptability, privacy and so on. The effect of implementing the measures was evaluated by a social survey, and their advantages and shortcomings were analyzed, which can be used to guide future epidemic prevention and control for rail transit systems around the world. It is important to formulate a reasonable work schedule according to local conditions, providing a reference for rapid response to future public health emergencies of international concern.

全球COVID-19大流行对全世界许多方面的发展都产生了重大影响。作为公共服务的重要组成部分，铁路运输需要有效的应对措施来控制COVID-19的传播。考虑到当前疫情的发展，本文讨论了COVID-19传播的特征并确定了易受攻击的区域，以预防和控制该疾病在轨道交通系统中的传播。根据外部和内部类别分析了为防止COVID-19传播而采取的对策，这些类别分为六类：旅客服务，案例护理，信息，人员，设备和运营管理。还建立了从有效性的角度建立的评估架构，经济效率，可接受性，私密性等。通过一项社会调查评估了实施这些措施的效果，并分析了它们的优缺点，可以用来指导世界范围内未来轨道交通系统的防疫工作。重要的是要根据当地情况制定合理的工作时间表，为快速应对国际关注的未来突发公共卫生事件提供参考。
