The reporter learned on the 22nd that recently, the national development and Reform Commission issued the multi-level Rail Transit plan for Chengdu Chongqing dual city economic circle (hereinafter referred to as the plan), which proposed that by 2025, the Chengdu Chongqing dual city economic circle on the track should be preliminarily built, with the total scale of rail transit reaching more than 10000 kilometers, forming a one hour commute circle in Chongqing and Chengdu metropolitan areas. According to the plan, the multi-level rail transit construction in Chengdu Chongqing twin city economic circle will take Chongqing and Chengdu "dual cores" as the center and Chengdu Chongqing main axis as the skeleton, coordinate the planning, layout and connection of trunk railway, intercity railway, municipal (suburban) railway and urban rail transit, accelerate the completion of intercity and municipal (suburban) railway short boards, and promote the "integration of four networks" of multi-level rail transit. Among them, in terms of building a trunk railway network with internal and external connections, strengthen the direct connection between Chengdu and Chongqing, build the Chengdu Chongqing middle line high-speed railway, and build a main direct passenger channel between Chengdu and Chongqing. Relying on Beijing Kunming Bao (Yin) Hai, LAN (West) Guangzhou, along the river, Xiamen Chongqing and other main high-speed railway channels, accelerate the construction of high-speed and common speed trunk railways, form a four-way expanded trunk railway network, and support Chengdu Chongqing region to quickly connect with other important urban agglomerations; fill the gap of the road network, appropriately strengthen the sections with tight capacity, build a large-capacity and efficient freight channel along the river, and improve the transportation of common speed railway channels such as the new land and sea channel in the West Yes, improve the layout of freight railway facilities. In terms of improving the fast and convenient intercity railway network, taking the Chengdu Chongqing main axis as the framework, the "dual core" radiation of Chongqing and Chengdu as the main body, and the node city connecting lines as the supplement, give priority to the use of Trunk Railways to run intercity trains, appropriately build intercity railways with passenger demand and guaranteed financial resources, improve the intercity railway network in Chengdu Chongqing, and realize the "dual core" direct connection The nodes of urban agglomeration are interconnected. According to the plan, by 2025, four-way channels in and out of Sichuan and Chongqing will be basically formed, forming a "one network" of facilities with clear functions and reasonable layout, a "zero transfer" hub with coordinated and efficient connection between points and lines, and a "integration" of passenger and freight transport and intermodal transport. The total scale of rail transit has reached more than 10000 kilometers, of which the scale of railway network has reached more than 9000 kilometers, covering all cities with a population of more than 200000, forming a 1-hour commute circle in Chongqing and Chengdu metropolitan area, realizing 1-hour access between Chongqing and Chengdu "double cores", and 1.5-hour access between "double cores" and regional centers and major node cities in Chengdu Chongqing, It is accessible to the core cities of major adjacent urban agglomerations for about 3 hours.
