Aerial photo taken on Nov. 26, 2019 shows a train running on a bridge over the Danjiangkou reservoir during a trial of Wuhan-Shiyan high-speed railway in central China's Hubei Province. Wuhan-Shiyan high-speed railway was put into operation on Friday. The railway line cuts half of the traveling time between Wuhan and Shiyan, making it more convenient for the passengers along the line. (Xinhua/Xiong Qi)
