Introduction to the Chongqing-Li Railway Line?

The Chongqing-Lichuan Railway Line (Chongqing-Lichuan) is a component of the Shanghai-Hanrong Express Passenger Transport Corridor in the "Four Vertical and Four Horizontal" rapid passenger transport corridors in China's "Medium and Long-term Railway Network Plan". It is a connection in China. Chongqing City and Lichuan City, Hubei Province are national railway Class I double-track electrified railway trunk lines that mainly carry passengers and also take into account freight.

The Yu-Li Railway does not use the existing Chongqing-Huaihua Railway section from Chongqing to Fuling, but a completely new line from Chongqing North Station to Liangwu Station in Lichuan City. It has a total length of 264.4 kilometers and is about 28 kilometers long in Hubei Province. It is designed as a national railway Class I trunk line with two-line electric traction. The designed operating speed is 200 kilometers per hour for high-speed trains and 160 kilometers per hour for double-decker container trains (high-end freight trucks).

The Yu-Li Railway connects with the Yiliang Section of the Yi-Wan Railway and the Wanliang Railway at Liangwu Station in Lichuan City. Construction started on December 29, 2008, with a total construction period of 5 years, ending on June 30, 2013 Fully connected.

On October 8, 2013, the Yu-Li Railway started joint debugging and testing; comprehensive testing was completed before November 1; Spring Festival transportation map adjustment was completed on December 20; station buildings along the line were delivered for use on December 24. It officially opened for operation on December 28.

At 9:10 a.m. on May 7, 2014, Yuli EMU No. D2266 named "Fengdu" departed from Chongqing North Railway Station. "Fengdu" will run 4 times a day The round trip from Chongqing to Lichuan also marked the launch of the first named train from Chongqing by the Chengdu Railway Bureau.

The entire line has eight stations: Chongqing North Station, Shuangxi Station, Fusheng Station, Changshou North Station, Fuling North Station, Fengdu Station, Shizhu County Station and Liangwu Station.

Project Introduction

Basic Overview

The Yuli Railway starts from Chongqing North Station in Yubei District, Chongqing City in the west, and passes through Yubei District, Changshou District and Fuling in the east District, Fengdu County and Shizhu Tujia Autonomous County, connected to Liangwu Station in Lichuan City, Hubei Province, and connected with Yiwan Railway to Lichuan Station. The total length of the line is 264.4 kilometers, with a bridge-to-tunnel ratio of 80%. The design standard is the National Railway Class I trunk line. The entire line is double-wire electric traction, and the design speed is 200 kilometers per hour. The total investment is 26.18 billion yuan, with 12 stations on the entire line. Construction started on December 29, 2008. The total construction period was 5 years and was completed at the end of 2013.

The line direction and the areas it passes

The Yu-Li Railway is an important part of the planned and constructed Shanghai-Hankong-Rongcheng Corridor. The line is located at the junction of my country's central and western regions.

The main line of the Yuli Railway starts from Chongqing North Railway Station in Yubei District, Chongqing City in the west, and passes through Tieshanping via the Yufengshan Tunnel (DK17+535). The line basically leaves the main urban area. This section of the line basically leaves the main city. It has intersected with municipal roads many times, resulting in a large amount of house demolition and numerous pipelines, lines and other facilities.

In Yubei District, basically follow the Yu-Changzhou Expressway at the edge of the slope of Zhangguan Baiyan Scenic Area, enter Changshou District at DK49+500, and cross the ferry about 3.5 kilometers away from Changshou New Town. The Changshou North Station is set up, and the Huangcaoshan Tunnel passes through the Huangcao Mountains into Fuling District. Fuling North Station is set up near Fuling Lidu Industrial Park.

After leaving Fuling Station, the line crosses the Yangtze River at DK118. From there, the line enters the low mountainous area and runs parallel to the Yangtze River along the right bank of the Yangtze River. Fengdu Station is set up at the foot of the mountain 3 kilometers away from Xinfengdu County. The line exits the station. Leaving the Yangtze River in the southeast direction, it basically follows the Long River, crossing the Long River six times to reach Shizhu County, where Shizhu Station is set up. The line continues eastward and sets up a Shasha station after passing through three long tunnels: Wanshoushan, Shaziguan and Xiangjiaba. This section of the line basically runs parallel to the Shizhong Expressway under construction.

The line exits Shaguan Station and enters Hubei Province at the exit of Dutingshan Tunnel. It passes through the Qiyue Mountains and enters the eroded hilly landform area of ??Lichuan City. Finally, it is introduced into the Yiwan Line through multiple continuous bridges. Liangwu Station.

Significance of construction

The construction of the Chongqing-Lichuan railway will help to form a Shanghai-Han-Chongqing express channel as soon as possible, effectively solve the problem of tight capacity of Chongqing’s external railway transportation channels, and open up the connection between Shanghai, Han and Chengdu. The double-layer container channel; it is conducive to promoting the coordinated development of the eastern, central and western regions, promoting the rapid development of the local economy and the stability of immigrants in the Three Gorges Reservoir area; it is also conducive to the implementation of the strategy of good and rapid railway development, building a developed and complete railway network, and comprehensively Improve the competitiveness of railways and build a "conservation-oriented society" and an "environment-friendly society." Therefore, the construction of the Chongqing-Lichuan railway has important significance and role in both the road network and the national economy.

Necessity of construction

This line can reach the city through the Sui-Chongqing Line to the west, and directly to Wuhan through the opened Yi-Wan Railway and Han-Yi Railway in the east, thereby connecting Hefei, Nanjing, Cities in the middle and lower reaches of the Yangtze River, such as Shanghai, can also be connected to regions such as North and South China through the Beijing-Guangzhou Railway, and to Jiangxi, Fujian and other provinces on the southeast coast through Wuhan and Jiujiang. This project is strategically located and is the most important main express railway transportation channel between Chongqing and East China, Central and South China, coastal areas and parts of North China. Together with the Xiangyu Line, Yuhuai Line and Chongqing Guizhou Line, it is responsible for the link between Chongqing and East China. Passenger and cargo exchanges in central China, North China and the southeastern coastal areas.

The electrification construction was completed.
