China News Service, Beijing, September 16 (Reporter Du Yan) Today, the reporter learned from the Beijing Major Project Office and Beijing Investment Corporation's railway company that the remaining section of Beijing Metro Line 8, the first phase of Line 19, the west extension of the airport line, The remaining section of S1 line has entered a three-month no-load trial operation stage, plus the remaining section of Line 14, the southern section of Line 17, and the western section of Line 11, which have started trial operation on September 10, are scheduled to open to traffic at the end of the year All of the 7 subway lines have officially entered the no-load trial operation stage.
The relevant person in charge of the Beijing Major Project Office said that most of these new lines that have entered the no-load trial operation are concentrated in the central city area, which is difficult to construct and debug. Many line stations use the existing line to carry out construction work during the evening outage. .
With the no-load trial operation, it marks that Line 8 will be completed and become the main line running through the north and south along the central axis of Beijing. Beijing’s first medium-to-low-speed maglev line S1 will be fully opened, and the first phase of line 19 will connect Beijing’s north and south. Another major artery of subway traffic in China.
According to the relevant person in charge of the railway company affiliated to Beijing Investment Corporation, according to the plan, the 7 lines that enter the no-load trial operation will be comprehensively tested and verified for vehicles, power supply, signal, communication and other systems during this period, as well as for people and equipment. , The system and the system are fully run-in, and will be put into operation after three months of no-load trial operation and strict acceptance.
It is understood that the remaining section of Line 8 is about 4.3 kilometers in length, starting from the National Art Museum Station in the second phase of Line 8 in the north and Zhushikou Station in the third phase in the south. There are three stations including Jinyu Hutong Station, Wangfujing Station and Qianmen Station. Among them, the transfer between Wangfujing Station and Line 1 can be realized, and the transfer between Qianmen Station and Line 2 can be realized.
The lines are all located within the core area and are interconnected with surrounding businesses. The design scheme is complicated, the site conditions are cramped, cross operations are frequent, and the construction is difficult.
After the opening of the remaining section of Line 8 at the end of the year, Line 8 will become a traffic trunk line that runs through the north and south, further improving the scope and quality of subway services and providing convenient conditions for people to travel.
The first phase of Line 19 has a total length of 22.4 kilometers. It starts from Xingong Station in Fengtai District in the south and ends at Mudanyuan Station in Haidian District in the north. There are 10 stations in total. All stations except Xinfadi Station and Niujie Station are transfer stations.
With an average station spacing of 2.3 kilometers, the line forms a "big station express" and "automatic driving" operation mode. It is the first line in Beijing to reach a speed of 120 kilometers per hour.
As the line passes through the central city and the geological environment is complicated, the construction unit combined with the actual project and the goal of opening to traffic to carry out the commissioning of high-speed trains in sections. The commissioning started on the same day, creating conditions for the follow-up full-line trial operation.
The west extension project of the Airport Line has a total length of about 1.8 kilometers. The starting point is at Dongzhimen Station on the existing Capital Airport Line. It is laid underground along Dongzhimen Inner Street and ends at Beixinqiao Station.
The project consists of one station and one section, and a transfer station is set up at Beixinqiao Station to transfer with the existing Metro Line 5.
After the completion of the west extension of the airport line, it will greatly relieve the pressure on the passenger flow of Dongzhimen Station, improve the overall system operation capacity of the Capital Airport Line, and effectively strengthen the connection between the Capital Airport Line and the rail transit network, expand the service scope of the Capital Airport Line, and depart from the central city. The Capital Airport will be more convenient.
The remaining section of the S1 line is about 1.2 kilometers in length, from Jin'anqiao Station to Pingguoyuan Station, with one station and one section. After the trial operation, it will lay the foundation for the implementation of the "three-line transfer" of the Pingguoyuan integrated transportation hub, which will effectively facilitate the surrounding residents to travel.
According to the relevant person in charge of the Beijing Major Project Office, according to the "2021 Beijing Urban Rail Transit Construction Plan", there are currently 15 lines under construction in Beijing, with a total length of 291.3 kilometers, and 7 lines (sections) of 54.5 kilometers are planned to be opened by the end of the year. As the largest number of lines open to traffic in the past years, Beijing's rail transit operating mileage will reach 781.5 kilometers after opening, which will further enrich and improve the city's rail transit network, open up line breakpoints, improve service capabilities, and better bear the capital's public transport travel The role of the main force.
