Hello, Lanzhou to Urumqi on Lanxin high-speed railroad takes more than 11 hours, while Chengdu to Lanzhou takes the old Baocheng line and takes a detour from Baoji, which takes more than 21 hours, so the fastest way from Chengdu to Urumqi is more than 30 hours at present. However, the Chengdu-Lanzhou Railway, which will be opened to traffic in 2018, will realize that Chengdu to Lanzhou can be reached within 6 hours, and then from Chengdu, you can get to Urumqi within 20 hours
