Chongqing–Lanzhou High-Speed Railway is a major trunk high speed railway selected for construction under the 11th Five Year Plan set by the Chinese Government. Construction started in 2010. The railway line is expected to be completed and opened for service by the end of 2016.[1] This will allow for high speed train travel between Chongqing and Lanzhou, Gansu via Nanchong and Guangyuan, Sichuan.

Introduction

With a total length of 820 km, of which 435 km is located within Gansu Province, in addition to the construction of a branch to Nanchong and Guang'an that is 95 km long. It is being built as a new double line electrified railway, with high-speed freight train capable of up to 160 km/h, high-speed passenger trains traveling at 200 km/h although the design speed has been set to 250 km/h. The capacity of the line is expected at 50 train pairs per day and 50,000,000 tonnes of freight per year.

Lanzhou-Chongqing railway project is estimated to need a total investment of 77.4 billion yuan, of which the Gansu Provincial Government is to invest about 43 billion yuan, with the rest of the funding coming from a Ministry of Railways, Sichuan and Chongqing joint construction effort. The construction period is expected to take 6 years. After the completion of Lanzhou-Chongqing railway, rail transport from Lanzhou and Chongqing will be shortened from 1466 kilometers to 820 kilometers, train running time is reduced to 6.5 hours from 17.5 hours.

Recent high speed rail reforms has also meant direct Chengdu-Lanzhou and Chongqing-Xi'an services will use a combination of Xi'an–Chengdu High-Speed Railway and Chongqing–Lanzhou High-Speed Railway from where they meet at Guangyuan, Sichuan. This will negate a need to build a separate direct Chongqing-Xi'an or Chengdu-Lanzhou lines.[2]

Because of hilly terrain between Guangyuan and Lanzhou on 832 km of railway there will be 285 bridges totaling 104 km (13% of the route) and 178 tunnels totaling 506 km (63% of the route). Twelve of the tunnels will exceed 10 km in length, while longest tunnel will measure 29 km.[3]

Route

Lanzhou-Chongqing Railway runs west out of Lanzhou City through Yuzhong County, Weiyuan County, Min County, Tanchang County, Longnan City in Gansu. Crossing into Sichuan Province territory, it then travels by Guangyuan, Cangxi County, Langzhong, Nanbu County, Nanchong. Finally it enters Chongqing City via Hechuan District and Beibei District before terminating at Chongqing North Railway Station.

Unlike most other previously constructed high-speed railways, the Lanzhou-Chongqing Railway will not parallel any existing "conventional" railways, but will follow an entirely new route, providing railway access to towns and counties that did not have railway service of any kind before.

History

The southern section of the line, from Chongqing to Guangyuan, opened in December 2015.[1] As of April 2016, it only has very limited passenger service.

Incidents

In October 2011, 21 railway workers were killed when the vehicle they were traveling in overturned in Lintao County, Gansu. Seven other workers were injured.[4]
