A test high-speed train pulls into the Epanggong Station on the Xi'an-Chengdu railway in Xi'an, capital of northwest China's Shaanxi Province, Sept. 20, 2017. The 643-km Xi'an-Chengdu railway, which links Xi'an, capital of northwest China's Shaanxi Province, and Chengdu, capital of southwest China's Sichuan Province, will come on stream within this year. By then, trains will run at a designed speed of 250 km per hour, slashing travel time between the two cities from 16 hours to three hours. (Xinhua/Tang Zhenjiang)
