*. The following is the introduction of Beijing Metro Line 9:
Beijing Metro Line 9 (hereinafter referred to as “Line 9”) is the first subway line in Beijing. Its construction is of great significance for improving the traffic conditions in the western part of the city, alleviating the traffic problems of Beijing West Railway Station, improving the travel conditions of Fengtai District, upgrading the city’s quality, and improving the investment environment.
Beijing Metro Line 9 starts from Guogongzhuang Station in Fengtai District in the south and Library Station in Haidian District in the north. The total length is 16.5km, with 13 stations and 1 depot. The line identification color is light green.
The southern section (except Fengtai East Street) was opened on December 31, 2011. Fengtai East Street Station opened on October 12, 2012. The northern section (except for the museum) was opened on December 30, 2012. *Museum Station opened on December 21, 2013.
The plan for Beijing Metro Line 9 appeared in the 1990s and is positioned as a vertical trunk line in the west of Beijing. In the Beijing Rail Transit Plan in 1999, the line 9 connects Guogongzhuang, Beijing West Railway Station, and Baishiqiao (. Library), which is roughly consistent with the line 9 line determined by .*; on the other hand, the line direction Go north through Zhongguancun, Old Summer Palace, and arrive at Xiangshan. This * line will be replaced by Line 4. In 2002, Line 9 was listed as one of the targeted routes to be opened in 2008, but further work was not implemented.
The underground structures of Beijing West Railway Station and Library Station were built earlier along with the railway station and Line 4. In 2007, Line 9 officially started construction. The Baiduizi Museum Station section will pass through the Yuyuantan Park Lake area. The East Lake of the park has been drained for half a year from the end of 2009, so that the shield machine can excavate in the ground with high pebble content.
The Guogongzhuang Depot Department has carried out the “superstructure development”, that is, the garage is supported by thickened steel plates, which are used as foundations to build houses and green areas, thereby saving urban land space. A similar scheme has been implemented in Sihui Depot (Line 1), and it has also been applied in Pingxifu Depot (Line 8) and Wulu Depot (Line 6) that were constructed at the same time as Line 9.
On July 17, 2011, a two-way tunnel between Guogongzhuang Station and Beijing West Station, which was about 10.8 kilometers long, was opened. On September 25 of the same year, the empty test operation began, and the passenger test operation was carried out on December 31, 2011 (Fengtai East). Dajie Station opened on October 12 of the following year). As Line 9 uses the outer track of Shuangdao Station at Beijing West Railway Station, it needs to enter the inner track reserved for Line 7 to make multiple U-turns during the turn-back process, which is difficult to operate. In addition, it runs off the network with the Fangshan Line*, resulting in passenger flow. Limited, so when it was first opened, Line 9 will take a guaranteed interval of 8 minutes and a minimum of 6 minutes.
Trial ride on the northern section of Metro Line 9
On November 1, 2012, the northern section of Line 9 began to operate without load according to the operation plan. On November 26, 2012, Beijing Rail Transit Construction Management Co., Ltd. invited some Beijing residents to the northern section of Line 9 for a trial ride. On December 30, 2012, the northern section of Line 9 was opened to traffic and officially connected to the subway network. The line opened this time is 5.35 kilometers long and has 4 stations (among them, the Museum Station was opened on December 21 of the following year).
