Have a look at China's Xi'an-Chengdu Passenger Railway

Aerial photo taken on Nov. 3, 2017 shows the Qingchuan Railway Station of the Xicheng high-speed railway in Qingchuan County of Guangyuan City, southwest China's Sichuan Province. The 643-km Xi'an-Chengdu Passenger Railway is China's first rail route to run through the Qinling Mountains. With a designed speed of 250 km per hour, it will slash the travel time between the two cities from the previous 16 hours. (Xinhua/Xue Yubin)
