Lanzhou-Xinjiang Railway is the longest railway trunk line built after the founding of New China, and it is an important part of the northwest railway network in China. On August 23, 2006, the whole line was put into double-track operation, and on February 23, 2065438+2002+3 1, the electrification reconstruction project of the whole line was completed and put into use.
After the completion of the second line of the 20 14 Lanzhou-Xinjiang Railway (Lanzhou-Xinjiang Express Railway), the old Lanzhou-Xinjiang Railway continued to be used, which greatly improved the logistics level in Xinjiang, continued to deepen Xinjiang's role as a bridgehead for China's opening to the west, and made important contributions to the formation and development of the Belt and Road. The National Development and Reform Commission has approved that the construction standard of Lanzhou-Xinjiang Second Line is passenger-freight trunk railway, and the planned transportation capacity is: 40 million passengers and 350 million tons of goods annually. In the long run, passenger transport is the mainstay, and freight is also taken into account.
Lanzhou-Xinjiang Railway is the main railway transportation line from Xinjiang to China and an important part of the northwest railway network in China. In the more than 30 years after the completion of Lanzhou-Xinjiang Railway, Urumqi Railway Bureau has carried out large-scale transformation of the line, gradually realized power connection and adopted electrical centralization. Advanced technologies and equipment such as semi-automatic block and wireless train dispatching have fundamentally changed the backward situation of technology and equipment, and increased the line capacity to 2 million tons, reaching the domestic advanced level. 1986, China realized the traction power diesel engine for the first time.
Lanzhou-Xinjiang Railway was built in 1952- 1962. After crossing the Yellow River westbound from Lanzhou, the line crosses Wushaoling at an altitude of 3,000 meters, enters Hexi Corridor at the northern foot of Qilian Mountain, passes through Wuwei, Zhangye and Jiuquan, exits Jiayuguan at the western end of the Great Wall, crosses Yumen and Shule River at the southern foot of Mazong Mountain, and crosses Liu Hong to the west and enters Xinjiang. After Weiya, it passes through Hami, Shanshan and Turpan along the southern foot of Tianshan Mountain, crosses Tianshan Mountain in Dabancheng to Urumqi, passes through military reclamation cities such as Shihezi, Kuitun and Bole, and finally reaches the border port city of Alashankou. Along the railway, there are not only Hexi Corridor with abundant water plants, but also Gobi Desert where nothing grows. There are both emerging industrial cities and ancient cities with splendid culture; There are both melons and fruits in vilen and a mirage. It is a steel transportation line integrating China's natural geography and human geography.
Lanzhou-Xinjiang Railway passes through "Baili Wind Zone" and "Sanli Wind Mouth", so the construction and transportation are extremely difficult. * * * subgrade earthwork110.83 million cubic meters was completed in the whole line; There are 33 tunnels with a total extension of11.8km; Bridge 1 1 17, with a total length of more than 30 kilometers; Track laying on the main line is 2423 kilometers. Hekou Yellow River Bridge, 35km away from Lanzhou West Railway Station, is the first Yellow River Bridge designed and built by China. Bridges and tunnels in Wushaoling area are relatively concentrated, and there are Tianshan tunnels between Hougou and Dabancheng, as well as subgrade projects across windy areas, which are all key projects in the construction of Lanxin Line.
Architectural history
1952, 10 and 1 day, Lanzhou-Xinjiang Railway broke ground, and on 1958 and 12, it was laid across Liuhong River at the junction of Gansu and Xinjiang, ending the history of no railway in Xinjiang. Lanzhou-Xinjiang Railway is 978 kilometers in Xinjiang, which is a straight line into Xinjiang. 19711February, 457 km of Turpan-Korla section of South Xinjiang Railway started construction, and it was officially put into operation in August. 1984. 1In May, 1985, the construction of the 476-kilometer west extension line of Lan Xin Railway was started from Wuxi Station to Alashankou Station, the border port between China and Kazakhstan. /kloc-0 was opened to traffic in September, 1990, connecting Lianyungang in China in the east and Rotterdam in the Netherlands in the west, making Xinjiang a bridgehead for China's opening to the outside world from a closed inland area. 1September, 1992, the construction of Lanzhou-Xinjiang double track with a total length of1622km was started, which was completed in only two years. The transportation capacity of Lanzhou-Xinjiang Railway has increased from 1992 to 30 million tons. After six speed-raising reforms in recent years, the number of passenger trains has reached about 70 million tons in 2009.
The opening of Lanzhou-Xinjiang Railway ended the history of no railway in Xinjiang and contributed to the economic construction of Xinjiang. Lanzhou-Xinjiang Railway has also played an important role in the development of western Gansu. Hexi Corridor, which the route passes through, includes Zhangye, Wuwei, Jiuquan, Yumen and other vast areas, and is rich in resources. In the past, the economy was depressed because there was no railway. After the Lanzhou-Xinjiang Railway was opened to traffic, the development of mineral resources, industry, agriculture and animal husbandry in these areas have made great progress. After Lanzhou-Xinjiang Railway arrived in Jiuquan, Jingtieshan Branch Line was built, and jiuquan iron and steel Factory was built, which has now become the main steel base in northwest China. It also built the Liu Qing branch line leading to Jiuquan Satellite Launch Center. Yumen oilfield used to be transported by car, and the scale was not large. After the completion of Lanxin line, Yumen branch line was built, and the oilfield developed rapidly. This route plays an important role in developing natural resources in northwest China, developing economy, strengthening national unity and consolidating national defense.
On September 22, 2006, the electrification section of Lanzhou-Xinjiang Railway in Wu Jia was fully put into operation. 2012 65438+February 311:26, Urumqi west station, two electric locomotives (HXD 1C) pulling the 57002 freight train slowly out of the station with the whistle, marking the Lanzhou-Xinjiang electrified railway.
