北京“新标准”：轨道交通设计时速提升至每小时120公里

Core Viewpoint - The Beijing Municipal Planning and Natural Resources Commission and the Beijing Market Supervision Administration have revised the local standard for urban rail transit engineering design, resulting in the new "Urban Rail Transit Engineering Design Standard," which will be implemented on January 1, 2026 [1] Group 1: Enhancements in Design Standards - The new standard increases the total chapters from 26 to 31 and raises the maximum operating speed from 100 km/h to 120 km/h [2] - New provisions for fast and slow train operations are introduced, with fast train speed efficiency not lower than 60% and slow train speed efficiency not lower than 40% [2] Group 2: Operational Efficiency - The standard specifies that during peak hours, the interval for regular lines should not exceed 4 minutes, and for fast lines, it should not exceed 6 minutes [3] - For peak hours, the maximum interval for regular lines outside the main service area should not exceed 6 minutes, while for fast lines, it should not exceed 10 minutes [3] Group 3: Passenger Experience Improvements - The standard emphasizes improving passenger transfer experiences, suggesting the installation of automatic walkways in long transfer corridors [4] - It encourages the inclusion of diverse convenience facilities at stations, such as retail shops, food and beverage areas, and self-service zones [4] Group 4: Safety and Environmental Standards - The standard details safety requirements for underground structures, enhancing anti-floating design and waterproofing measures [5] - It sets energy-saving requirements for lighting, ventilation, and air conditioning systems, promoting the use of energy-efficient equipment [5] - The standard supports prefabricated intelligent green construction technologies, including design requirements for prefabricated stations and tracks [5]
