Lanzhou-chongqing railway originated from Dr. Sun Yat-sen's founding strategy, and the planned route is basically "Lanzhou-Guangyuan-Nanchong-Chongqing". Dr. Sun Yat-sen pointed out in the General Plan for the Founding of the People's Republic of China that this line "passes through a region rich in products and minerals" and "is the most important railway system in China". At the same time, it was included in the top priority of the central railway system of the National Government.
After the founding of New China, the relevant departments have conducted preliminary work such as demonstration, survey and design for this railway for many times. As early as 1950s, the Ministry of Railways organized the survey of Guangyuan-Chongqing section, but actually only the Guangyuan-nanbu county section was surveyed, which was later stopped for some reason.
1994, initiated by Cangxi, Langzhong and southern Sichuan, counties and cities along the 2 12 national highway in Sichuan and Gansu provinces jointly established the "lanzhou-chongqing railway Project Establishment Cooperation Meeting". Since then, 105 old Red Army cadres have signed a letter and obtained the personal instructions of the State Council Prime Minister Zhu Rongji about lanzhou-chongqing railway at that time. By the year 2000, the lanzhou-chongqing railway Project had officially entered the work target of the people's governments of three provinces and cities. In 2005 and 2007, the people's governments of the three provinces and cities submitted two proposals for the construction of the Lanzhou-Chongqing Railway to the National Development and Reform Commission.
The main line enters from Longnan, Gansu. Duyao Town in Qingchuan is the first stop in Sichuan, and then passes through Yangmu Town to Guangyuan Station. Guangyuan will have three stations: Guangyuan, Guangyuan West and Guangyuan South. Then it passes through Yuanba, Cangxi, Langzhong ancient city, goes south, the first mouth of Jialing River goes south, goes out of Sichuan from Wusheng County, Guang 'an, then enters Chongqing at Hechuan Station and meets suining-chongqing railway in Hechuan City, Chongqing. In addition to the main line, there is also a Guang 'an branch line, which is planned to lead from Nanchong East Station of Dacheng Railway in Nanchong City, and connect with Xiangyu Line after passing through Yuechi County and Guang 'an. According to the design, the main line of the line is built according to the 200 km/h double-track electrified railway, and the branch line is designed according to the 160 km/h single-track electrification standard.
Lanzhou-chongqing railway will set up Langzhong Station in Jiangnan New District, 3 kilometers away from the ancient city of Langzhong, designed according to the waiting standard of 2,000 people. Besides Lanzhou and Chongqing, Nanchong and Guangyuan, Langzhong Station will be the largest station on the line.
The length of the bridge and tunnel line is about 560 kilometers, accounting for about 70% of the total length of the line. It is predicted that in 2020, the freight from Lanzhou to Guangyuan will be 24 million tons/year, 20 pairs/day of buses, 0/60,000 tons/year of freight from Guangyuan to Chongqing and 22 pairs/day of buses. In 2030, the freight from Lanzhou to Guangyuan will be 32 million tons/year, 28 pairs/day of buses, 20 million tons/year of freight from Guangyuan to Chongqing, and 32 pairs/day of buses. There are 30 stations and 2 line stations on the whole line.
Through the Qinling Mountains and Sichuan Basin.
On September 26th, 2008, the construction of lanzhou-chongqing railway, the traffic artery across Gansu, Sichuan and Chongqing, started in Lanzhou. The Lanzhou-Chongqing line crosses the Baocheng line south of the Longhai line near Guangyuan, Sichuan, forming a huge X-shape. It connects Lanxin Line, Baolan Line, Lanqing Line and Qinghai-Tibet Line in the north, Huai Yu Line in the south, connecting the Yangtze River Basin and the Yellow River Basin, crossing the western resource-rich areas, and crossing two western provinces and a municipality directly under the central government. It is the shortest and most convenient passage from northwest to southwest.
After the completion of lanzhou-chongqing railway, the railway distance from Lanzhou to Chengdu and Chongqing will be shortened from 1 172 km and 1466 km to 836 km and 820 km respectively, and the running time of passenger cars will be shortened from17.5h and 22h to 7.5h and 6.5h respectively. According to the preliminary calculation of the railway department, after the completion of lanzhou-chongqing railway, the railway freight from Lanzhou to Chengdu and Chongqing will be reduced by about one third, and the time will be shortened by about two thirds, which has great economic and social benefits.
Lanzhou-chongqing railway is designed as a national railway I-class, double-track electrified railway. The target speed of passenger cars is 160km/h, and the planned transportation capacity is 50 pairs of passenger cars/day and 50 million tons of freight/year. Lanzhou-chongqing railway is a convenient, fast and large-capacity transportation channel between northwest and southwest regions. The completion of this important traffic trunk line is conducive to promoting social and economic development along the line, speeding up people along the line to get rid of poverty and become rich, building a well-off society in an all-round way, strengthening the connection between southwest and northwest, and narrowing the gap between time and space.
If lanzhou-chongqing railway extends from Chongqing to Guangzhou via Huaihua, Shaoyang, Hengyang and Chenzhou, it will form an artery connecting northwest, southwest and Pearl River Delta. From Lanzhou to Chongqing, then through Huaihua, Wugang, Yongzhou, Chenzhou and Ganzhou, and finally to Xiamen, the Lanzhou-Xiamen Railway was expanded to become a channel connecting the northwest, southwest and Fujian triangles.
Lanyu Line passes through Linxia Hui Autonomous Prefecture and Gannan Tibetan Autonomous Prefecture in Gansu Province, and is close to Aba Tibetan and Qiang Autonomous Prefecture in Sichuan Province. These three states are also the borders of Tibetan, Hui, Qiang and other ethnic minorities and Han. In particular, the Lanzhou-Guangyuan section runs through the Tibetan-Hui inhabited area for 600 kilometers. The construction of lanzhou-chongqing railway is conducive to the development of local ethnic economy, changing the closed and backward appearance of ethnic areas, forming a lifeline connecting southwest and northwest, and building the Qinba Economic Corridor. This will play an extremely important role in strengthening national unity, ensuring the peace of one party and maintaining political stability in the western region. At present, due to the restriction of backward traffic, especially the lack of railway transportation, the economic development along lanzhou-chongqing railway is extremely backward. Among the 25 counties and cities that the line passes through, there are 13 national key poverty alleviation counties and 4 provincial key poverty alleviation counties. The per capita net income of farmers in many counties is less than 2000 yuan. However, there are abundant resources of agriculture and animal husbandry, nonferrous metal (lead-zinc mine), coal, building materials and cultural tourism along lanzhou-chongqing railway. The construction of lanzhou-chongqing railway is conducive to the development of various resources along the route, transforming resource advantages into economic advantages, accelerating the pace of getting rid of poverty and building a well-off society in an all-round way in old, less, border and poor areas, and effectively improving the living standards of people along the route.
Lanzhou-chongqing railway starts from Xining to Golmud in the north, connecting lines, Lanqing line, Baolan line and Qinghai-Tibet line, opening another north exit for the southwest, connecting Chongqing Huai (Hua) line in the south, connecting Hunan-Guizhou, Beijing-Guangzhou, Zhejiang-Jiangxi, Guizhou-Guangxi, Hunan-Guangxi-Guangzhou line in the north, and connecting Sichuan Baocheng (Du) line and Chengda line in the north. At the same time, lanzhou-chongqing railway can connect the Yellow River and the Yangtze River, which is equivalent to building another "steel" bridge in the upper reaches of the two major river basins. Building the Lanzhou-Chongqing railway as soon as possible is also conducive to improving transportation capacity and consolidating national defense. At present, there is only one baoji-chengdu railway connection in the southwest and northwest areas with complex geological structure and tight transportation capacity, and there are many detours and long time. The passenger and freight traffic between the two places is easily restricted by the "bottleneck" in the northern section of this line, which invisibly increases the transportation cost. According to the calculation of the First and Second Institutes of the Ministry of Railways, the mileage from Chengdu to Lanzhou, Gansu via this line is 139 km shorter than that via the existing line (Baocheng-Baolan line), saving nearly 3 hours. Compared with the existing line (Chengdu-Chongqing Baocheng-Baolan Line), the mileage from Chongqing to Lanzhou via this line is shortened by 5 1 1 km, and the time is saved by 10 hour. The construction of Lan-Yu line can not only divert part of the traffic volume of Baocheng line, break the bottleneck of the line and reduce its transportation load, but also shorten the transportation distance and time and improve the transportation capacity. Moreover, Lanzhou-Chongqing railway can be connected with the proposed Qinghai-Tibet railway through the Jialing River combat readiness channel determined by the Central Military Commission, which has potential strategic value for consolidating the southwest frontier.
Lanzhou-chongqing railway, as one of the leading post-earthquake reconstruction and supporting infrastructure projects, will provide long-term transport capacity guarantee for post-earthquake reconstruction and economic and social development, which fully reflects the firm support of the state for the restoration and reconstruction of disaster areas along the route, and will certainly inspire the confidence and determination of people in earthquake-stricken areas to speed up reconstruction.
