With the opening of two important trunk railways, the intensive commissioning period of railway projects this year has arrived. On November 28, the Zhenjiangguan to Qingbaijiang section of the Sichuan-Qingdao Railway was opened, which marked the first railway in northwest Sichuan.
Two days earlier, on November 26, the Lijiang-Shangri-La section of the Yunnan-Tibet Railway was officially put into operation, ending the history of Shangri-La's lack of railway.
According to the commissioning plan of the China Railway Group, it is expected that a number of railway lines will be opened as scheduled in the last month of this year. These lines include the Jipu section of the Jizheng high-speed railway, the Lairong high-speed railway, the Jinxing intercity railway, the Chengyi high-speed railway, the Changjinghuang high-speed railway, the Shanwei-Shantou southern section of the Shantou-Shantou high-speed railway, the Longyan-Wuping section of the Longlong high-speed railway, the Fangdong railway, and the Xubi railway.
On December 1, the Gu'andong to Shengfang section of the Beijing-Tianjin-Hebei Intercity Railway successfully passed the preliminary acceptance, taking another solid step towards high-quality opening.
Preliminary acceptance is an important part after static acceptance and dynamic acceptance, and then it will enter the stage of security assessment and operational preparation. China Railway Group, Hebei Province and Tianjin Municipality jointly set up a preliminary acceptance committee, and the inspection team was led by Tang Xiaoguang, director of the Construction Department of China Railway Group, to listen to the reports of relevant units, sample inspection of internal information, add test trains to check the line, and check the construction of the site.
Zhong Shenggui, chairman of the company, and Zhu Pengfei, general manager of the company, led a team to attend the meeting, and relevant personnel of Beijing Bureau Group and various participating units participated in the preliminary acceptance. The construction of the Jinxing Intercity Railway started in August 2020, the girder erection was completed on September 13, 2022, and the track laying of the whole line was completed on April 6, 2023. Under the correct leadership of the China Railway Group and the strong support of the local government, the company, together with the Beijing Bureau, organized all participating units to conscientiously implement the relevant requirements of quality, safety, construction period, investment and construction in accordance with the law, and promoted the project construction with high-standard design, high-quality construction and high-efficiency management, and achieved two "100%" (100% solution before the implementation of design problems and 100% solution before static acceptance of quality problems), and completed the joint debugging and joint test in only 32 days. Public Works Track Integrated TQI Downlink 269, upward 27. The CDI management score of catenary is 100 points, which has achieved the project construction goal.
Jinxing Intercity Railway is a landmark project to implement the major national strategy of coordinated development of Beijing-Tianjin-Hebei, and is the fifth railway trunk line connecting Beijing-Tianjin after Beijing-Tianjin Intercity, Beijing-Shanghai High-speed Railway, Beijing-Bin Intercity and Beijing-Shanghai Railway. After the project is put into operation, Tianjin, Beijing Daxing International Airport, Yongqing County, Anci District and other cities and counties along the route will form a "half-hour traffic circle", which will have a far-reaching impact on improving the layout of the regional road network, promoting the transportation integration of the Beijing-Tianjin-Hebei region and the coordinated development of regional economy and society.
