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

Residents look at the sketch map of Xi'an-Chengdu Passenger Railway in Xi'an, capital of northwest China's Shaanxi Province, Oct. 27, 2012. The 643-km line 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)
