Since the outbreak of COVID-19，the urban rail transit industry has experienced an unprecedented test. Based on the investigation of urban rail transit enterprises，this paper summarized the measures taken by enterprises during the epidemic period and their effects from the aspects of passenger service management，equipment and facilities cleaning and disinfection，epidemic prevention materials management and internal personnel control. The results showed that the main measures for passenger management were temperature measurement at the station，wearing masks on the bus，setting up observation area and emergency treatment of febrile persons. In the aspect of passenger flow control，it is difficult to accurately control the train load ratio，and the technical means of passenger tracking are limited. At the same time，there is still a gap in the construction of public health emergency management system and emergency information platform.
