Project introduction
Basic overview
Chongqing-Lichuan Railway starts from Chongqing North Station in Yubei District of Chongqing in the west, and goes to Yubei District, Changshou District, Fuling District, Fengdu County and Shizhu Tujia Autonomous County in the east, connecting with Wuliang Station in Lichuan City, Hubei Province, and connecting with Yiwan Railway to Lichuan Station. The total length of the line is 264.4 kilometers, and the bridge-tunnel ratio is 80%. The design standard is the national railway I trunk line, the whole line is double-line electric traction, and the design speed is 200 kilometers per hour. With a total investment of 2.6/kloc-0.80 billion yuan, the whole line has two stations/kloc-0.2, which started on February 29, 2008, with a total construction period of 5 years and was completed by the end of 20 13.
Route direction and passing area
Chongqing-Lichuan Railway is an important part of the planned Shanghai-Han Rong corridor. The line is located at the junction of central and western China, starting from Yubei District of Chongqing in the west, and ending in Lichuan City, Enshi Tujia and Miao Autonomous Prefecture, Hubei Province, with Jiangbei District, Changshou District, Fuling District, Fengdu County and Shizhu County of Chongqing in the east longitude.
The main line of chongqing-lichuan railway starts from Chongqing North Station in Yubei District of Chongqing in the west, passes through Tieshanping and Yufeng Mountain Tunnel (DK 17+535), and basically leaves the main city. This section of the line crosses municipal roads many times, resulting in a large amount of house demolition and many facilities such as pipelines.
In Yubei District, the line basically follows the Chongqing-Changzhou Expressway at the foot of the slope of Zhang Guan Baiyan Scenic Area, enters Changshou District at DK49+500, and sets Changshou North Station on the ferry about 3.5 kilometers away from Changshou New City, and enters Fuling District through Huangcaoshan Tunnel, and sets up Fuling North Station near Fuling Lido Industrial Park.
After leaving Fuling Station, the line crosses the Yangtze River at DK 1 18, and enters the low mountainous area along the right bank of the Yangtze River from there, parallel to the Yangtze River. Fengdu Station is located at the foot of the mountain 3 kilometers away from Xinfengdu County. When the line leaves the Yangtze River in the southeast, it basically runs along the Longhe River, crosses the Longhe River six times, and sets up Shizhu Station. The line continues eastbound, and a sand station is set up after passing through three long tunnels: Wanshoushan, Shaiguan and Xiangjiaba. This line is basically parallel to the downtown expressway under construction.
After the line leaves Shaguan Station, the elevation line enters Hubei Province at the exit of Dutingshan Tunnel, passes through Qiyueshan Mountain Range and enters the karst residual hill landform area of Lichuan City. Finally, several continuous bridges are introduced into Wuliang Station of Yiwan Line.

Significance of architecture
The construction of Chongqing-Lichuan railway is conducive to the rapid formation of Shanghai-Han-Yu expressway as soon as possible, effectively solving the problem of tight capacity of Chongqing's foreign railway transportation corridor and opening up the double-deck container corridor of Shanghai, Han and Rong; It is conducive to promoting the coordinated development of the eastern, central and western regions, promoting the rapid development of local economy and the stability of immigrants in the Three Gorges reservoir area; At the same time, it is also conducive to implementing the strategy of sound and rapid railway development, building a developed and perfect railway network, comprehensively improving railway competitiveness, and building a "conservation-oriented society" and an "environment-friendly society". Therefore, the construction of Chongqing-Lichuan railway is of great significance and function to the road network and the national economy.
Necessity of construction
This line can reach the urban area through the Suiyu line to the west, and the Yiwan Railway and Hanyi Railway, which have been opened in the east longitude, go directly to Wuhan, and then communicate with Hefei, Nanjing, Shanghai and other cities in the middle and lower reaches of the Yangtze River. You can also connect North China and South China through the Beijing-Guangzhou railway channel, and connect Jiangxi, Fujian and other provinces and regions along the southeast coast through Wujiu. The project has a superior geographical position, and it is the most important main express railway transportation channel connecting East China, Central South China, coastal areas and parts of North China in Chongqing. * * * * Together with Xiang-Yu Line, Yu-Huai Line and Yu-Qian Line, it undertakes the passenger and cargo exchange between Chongqing and the eastern, central, north and southeast coastal areas.
Electrification Construction Completed on September 1 1 2065438, a special inspection vehicle carrying various inspection instruments carried out a cold-slip test on the Yulichuan Railway at a speed of 40 kilometers per hour, marking the basic completion of the electrification project of the line and entering the final countdown stage of power transmission and opening. With the Chongqing-Lichuan Railway expected to open to traffic before the end of 20 13, the entire Shanghai-Han Rong passenger corridor will also be fully connected.
