The Lanzhou–Zhangye high-speed railway is a high-speed rail line from Lanzhou to Zhangye, both in China's Gansu Province. The line runs along the Hexi Corridor and roughly parallels the Lanzhou–Xinjiang railway. Once fully completed it will form an alternative route to the Lanzhou–Xinjiang high-speed railway.
The line is constructed by China Railway Construction Corporation and designed for operations up to 250km/h.[1] [2]
