Abstract: Objective: The design and maintenance concepts of metro depot in China are relatively outdated. It is necessary to combine new concepts and ideas in the construction of metro depot, and propose practical recommendations for optimizing the design and construction of metro depot. Method: Taking into account the era background of China in terms of high\|quality and sustainable urban rail transit development, a thorough analysis is conducted on the problems existing in the metro depots, such as outdated facilities and equipment, lagging vehicle maintenance processes, and asynchronous integration of TOD (transit\|oriented development). Based on the experiences of metro depot construction in China, taking into consideration the actual operational needs, combining the development of intelligent and informatized technologies, as well as the application of new technologies in rail transit both domestically and internationally，key aspects such as the intelligent, informatized, green and energy\|saving construction, and the integration of TOD are analyzed, recommendations for the design and construction of urban rail transit metro depots under high\|quality development are proposed. Result &Conclusion: The design of metro depot should focus on top\|level layout and high\|point positioning, gradually constructing intelligent system, improving the level of humanization, promoting green and energy conservation, and advancing the integrated construction of TOD.
