Since the beginning of this year, the construction of railway projects in many parts of the country has continued to advance and made new progress. Reporters learned from China National Railway Group Corporation on the 13th that in the first half of this year, the fixed assets investment of national railways was 355.9 billion yuan, up 5.5% year on year. A total of 301 kilometers of new lines were put into production, and the construction of modern railway infrastructure system was accelerated. The relevant person in charge of China Railway Group stated that since the beginning of this year, the railway department has fully utilized the advantages of the long industrial chain, wide radiation, and obvious driving effect of railway construction investment, coordinated the use of resources, solidly promoted railway planning and construction, and maintained a high level of railway construction investment. Recently, a batch of new lines and stations have been put into operation. The newly built Chongqing Xiamen high-speed railway from Chongqing East to Qianjiang has been put into operation, and the Chongqing Xiamen high-speed railway from Chongqing East to Changsha has been connected; The section from Songcheng Road Station to Kaifeng Station of Zhengzhou Kaifeng Intercity Railway has been completed and opened to traffic, and the Zhengzhou Kaifeng Intercity Railway has achieved full line operation; The newly built Chongqing East Station has been put into operation, the renovation and upgrading project of Cangzhou Station has been completed, and the newly renovated Rizhao Station has been put into use. The key railway hub functions have been significantly improved. At the same time, ongoing construction projects are progressing smoothly. Each participating unit strengthens safety, quality, investment, and environmental control, strives to complete more physical work, and strives to create high-quality projects. In Sichuan, the first double track box girder of the Chengdu Chongqing Middle Line High speed Railway over Suining Nei High speed Extra large Bridge, constructed by China Railway 19th Bureau, was erected, weighing 541.5 tons, accumulating experience for large-scale beam erection operations in the future. In Guizhou, the Yangjiahe Extra Large Bridge on the Huangbai Railway, constructed by China Railway 23rd Bureau, is intensively carrying out pier construction. Its highest pier is 117 meters high, which is the highest pier on the Guizhou section of the Huangbai Railway. In Guangdong, the construction of the ballastless track bed for the control engineering high school interchange super large bridge of the Guangzhou Zhanjiang high-speed railway, undertaken by China Railway 25th Bureau, has been completed. The total length of the bridge is 5101 meters, and the builders have successfully controlled the installation accuracy error of the track plates within 2 millimeters, achieving "millimeter level" accuracy. In addition, the railway department focuses on the railway engineering and key networking, supplementary network, and strong chain projects identified in the national "14th Five Year Plan" outline, vigorously carrying out preliminary work such as new project survey and design, feasibility study, and preliminary design. At present, positive progress has been made in the preliminary work of projects such as the Yining Aksu Railway, the addition of a second line to the Guizhou Guangxi Railway, and the Wenzhou Fuzhou High speed Railway, laying the foundation for early construction.
