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 was built as a new double line electrified railway, with freight train capable of up to 160 km/h, passenger trains traveling at 200 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 was estimated to need a total investment of 77.4 billion yuan, of which the Gansu Provincial Government invested about 43 billion yuan, with the rest of the funding was coming from a Ministry of Railways, Sichuan and Chongqing joint construction effort. The construction period was expected to take 6 years. By the completion of the railway rail transport from Lanzhou and Chongqing is shortened from 1466 kilometers to 820 kilometers, conventional train running time is reduced to 7 hours from 17.5 hours. Fast trains will complete the route in 5.5 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 reduce the need for a separate direct Chongqing-Xi'an or Chengdu-Lanzhou line.[3]
Because of hilly terrain between Guangyuan and Lanzhou on 832 km of railway there are 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 the longest tunnel, West Qinling Tunnel, measures 29 km.[4]
