　　【Abstract】 With the rapid urbanization and promotion of urban agglomeration in metropolitan areas in China, urban express rail transit lines have a rapid development trend. The express rail transit planning and design, as well as its construction and operation, are not satisfying in China, while the industry development is still evolving with signif-icant issues to address. With a summary of planning and construction, operation performance, technical standards, and main problems in practical cases of urban express rail transit lines in China, this paper uses trend prediction, case analysis, and horizontal analogy to address several key issues, such as the interactive coordination between network planning of express rail transit lines and urban land use planning, appropriate construction timing adapted to urban development, and reasonable system formats and technical standards. The paper concludes that key factors to increase passengers flow and level of service of express rail transit lines include direct access to urban core areas, effective connections with different travel modes, and the network-based and high frequency operation of metropol-itan railway. The paper also suggests scientifically developing a standard system of express rail transit lines and identifies main issues to be addressed in the future.
