A railway staff worker records the data of bullet train 55861 at Hanzhong Railway Station during a test run on a high-speed railway linking Xi'an of northwest China's Shaanxi Province with Chengdu of southwest China's Sichuan Province, Nov. 22, 2017. The first full-course test run was carried out Wednesday on the Xi'an-Chengdu high-speed railway, which is scheduled to enter operation within the year. 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 to 3 hours. (Xinhua/Tao Ming)
