Lanzhou–Chongqing railway or Lanyu railway (Chinese: 兰渝铁路; pinyin: Lán-Yú tiělù, "Lan" and "Yu" being the abbreviations for Lanzhou and Chongqing) is a higher-speed railway in China connecting Lanzhou and Chongqing. Construction started in 2010, last segment of the railway was opened for service in September 2017.[1][2] The line allows trains to travel between Chongqing and Lanzhou, Gansu via Nanchong and Guangyuan, Sichuan.

Introduction

With a total length of 820 km (510 mi), of which 435 km (270 mi) is located within Gansu Province, in addition to the construction of a branch to Nanchong and Guang'an that is 95 km (59 mi) long. It was built as a new double line electrified railway, with freight train capable of up to 160 km/h (99 mph), passenger trains traveling at 200 km/h (124 mph). The capacity of the line is expected at 50 train pairs per day and 50,000,000 tonnes of freight per year. The railway is designed to permit double-stack container operations.[3]

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 1,466 kilometres (911 mi) to 820 kilometres (510 mi), 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.[4]

Because of hilly terrain between Guangyuan and Lanzhou on 832 km (517 mi) of railway there are 285 bridges totaling 104 km (65 mi) (13% of the route) and 178 tunnels totaling 506 km (314 mi) (63% of the route). Twelve of the tunnels will exceed 10 km (6.2 mi) in length, while the longest tunnel, West Qinling Tunnel, measures 29 km (18 mi).[5]
