High altitude high-speed trains. The Lixiang Railway has been put into operation, and the first section of the Chuanqing Railway in Sichuan has been opened. By the end of November, the history of railway closures in Diqing Tibetan Autonomous Prefecture in Yunnan and Aba Tibetan and Qiang Autonomous Prefecture in Sichuan has gradually ended. The high-speed rail is entering the airport. The Jinxing Intercity Railway is undergoing trial operation and will officially open within the year. At that time, you can take the high-speed rail directly from Beijing Daxing Airport to Tianjin, adding a new touch to the "Beijing Tianjin Hebei" railway. According to the data of State Railway Group, from January to October, the fixed assets investment of national railways reached 572.6 billion yuan, up 7.2% year on year; In the whole year, the railway is expected to complete more than 760 billion yuan of fixed assets investment, and more than 3000 kilometers of new lines are expected to be put into production. Towards the end of the year, the construction of railways across the country has entered a period of intensive investment and production: the opening of the Changjing Huang high-speed railway is imminent, marking the imminent completion of the entire Hangchang high-speed railway line; The trial operation of the Guangxi Fangchenggang Dongxing Railway started on December 2nd, and the border city of Dongxing between China and Vietnam is about to be connected to the national railway network... Especially in the western region, the complex geology has always been the "backbone" of railway construction. Since the beginning of this year, with new progress made in a number of railway projects such as the Guinan High Speed Railway, Chuanqing Railway, Lixiang Railway, and Chengdu Ziyi High Speed Railway, the construction of western railways has accelerated. Data shows that from January to October, fixed assets investment of railway projects under construction in Chongqing, Sichuan and Guizhou reached 84.46 billion yuan, up 20.23% year on year. How difficult is it to gnaw on "hard bones"? The Chuanqing Railway transitions from the Chengdu Plain to the Qinghai Tibet Plateau, crossing active fault zones 11 times, and is listed by the design unit as one of the most difficult railways to repair in China. Wang Xiaoguang, the chief engineer of China Railway 12th Bureau Project, admitted that the Liutongzhai Tunnel is the most difficult tunnel he has ever participated in, with a total length of 16.4 kilometers and a 5-minute train passage. The construction project took 10 years. What is the significance of gnawing on "hard bones"? Wang Xiaoguang said, "The entire construction process takes two steps and one step back, but only by persevering can we break through the 'expressway' connecting the western region with the outside world." On the day before the opening of the Sichuan Qingdao Railway, Liu Yongming, a 67 year old resident of Maoxian County, Sichuan, sent a message to his daughter in Guangzhou: "The high-speed train has arrived at our doorstep. This year, during the Chinese New Year, your whole family must come back." With the growth of railway investment in China, The world's largest high-speed railway network continues to be densified: in Heilongjiang, the construction of the northernmost high-speed railway Harbin Iraq high-speed railway ushers in new progress, and the northernmost high-speed railway station under construction Yichun West Station has been capped; In Guangdong, the Shanwei to Shantou South section of the Shanshan high-speed railway entered the trial operation phase on November 25th, entering the countdown mode for operation; In Shaanxi, the highly anticipated Yan'an Yulin high-speed railway has started construction, and the "Happiness Road" on the loess ground continues to spread. Data shows that from January to November, 1636 kilometers of new railway lines were put into operation nationwide, including 1488 kilometers of high-speed railways; As of the end of November, the operating mileage of railways in China reached 155500 kilometers, including 43700 kilometers of high-speed railways. The tide is surging, and the magnificent scenery is like this. In the first 10 months, the total railway freight volume in China was 4.172 billion tons, a year-on-year increase of 0.7%, and the passenger volume was 3.285 billion people, a year-on-year increase of 119%. Relying on one railway after another, the mobile China is even more vibrant. (Lai Xin She)
