"Fuxing" will drive on the Qinghai-Tibet Railway The "Magic Sky Road" will be upgraded to create another miracle
【The miracle we have created over the years (9)】
Lhasa, 5 May (Reporter Zhan Yuan and Gama Dorji) The Qinghai-Tibet Railway has spread good news again -- the "Fuxing" EMU will drive on the Qinghai-Tibet Railway for the first time! The reporter recently learned from China Railway Qingzang Group Co., Ltd. that the quality upgrading of the Qinghai-Tibet Railway has entered a new stage, and the Xining to Golmud section is expected to complete the upgrade this year, and the running time of the 2.829 km line of this section will be shortened to less than 251.5 hours, and the shortest is 2.4 hours, which is nearly 8 hours shorter than the 6.8 hours of the current fastest train. A more modern Qinghai-Tibet Railway will see a significant increase in transportation capacity and service quality.
The Qinghai-Tibet Railway runs from Xining City, Qinghai Province in the east to Lhasa City, Tibet Autonomous Region in the west, with a total length of 1956,<> kilometers, making it the world's highest altitude and longest plateau railway.
The Qinghai-Tibet Plateau has high altitude, steep terrain, complex terrain, and extremely closed traffic. At the beginning of the founding of New China, more than 4,1 camels had to be used to transport materials to Tibet, and the consumption along the way was huge, with an average of 12 camels lost for every 20 kilometer traveled. The <>th-century American traveler Paul Teru once asserted: "With the Kunlun Mountains, the railway will never reach Lhasa." ”
In 1958, construction began on this "most difficult railway in the world to repair". The first phase of the project was completed in May 1984; The second phase of the Golmud-Lhasa section was started in 5 and opened to traffic in 2001.
After decades of unremitting efforts, the construction of the Qinghai-Tibet Railway has broken through three world-class engineering problems, such as cold and lack of oxygen, permafrost, and fragile ecology. The completion and operation of the train broke the curse of Tibet's lack of railway, and the vast snowy land and majestic Kunlun witnessed this miracle in the history of the world's railway!
According to data from China Railway Qingzang Group Co., Ltd., from its opening in 2006 to the end of 2022, the Qinghai-Tibet Railway has transported a total of 8 million tons of cargo and 03 million passengers.
Today, this "magic road" will be faster and more stable. "This quality improvement and renovation began in July 2022, from Xining all the way west through Huangyuan, Haiyan, Gangcha, Tianjun, Ulan, Delingha to Golmud." Wang Qingan, director of the technical construction department of the Xining Station Reform Headquarters of China Railway Qingzang Group Co., Ltd., said: "After replacing the EMU, the power is increased, and the speed of passenger trains can be increased from the original 7 to 120 kilometers per hour to 140 kilometers per hour. More trains can be added to increase capacity. ”
It is reported that one of the difficulties in this quality improvement and transformation is to rectify the freezing damage of the plateau railway roadbed, especially the section around Qinghai Lake. "Groundwater is abundant here, and if the roadbed is not well drained, it will cause stagnant water, frost heave in winter, which will cause track deformation, and the train may 'shake' when running." Wang Qingan said, "After rectification, the smoothness of the track will be better, so that the train can run fast and stable." ”
The renovation will also strengthen bridges and culverts, comprehensively improve the quality of equipment in the Xige section, build a new Haiyan station building, and renovate and expand the Delingha station building to allow EMUs to operate and stop. In terms of station reconstruction and expansion, Delingha Station in the hinterland of the Qaidam Basin, the largest intermediate station in the Sige section, will be expanded from 5200,10700 square meters to 2000,<> square meters, and a new station building of <>,<> square meters will be built at Haiyan Station, and the main structure has been completed.
