Aerial photo taken on Aug. 3, 2021 shows passenger train No. G9147 from Jinzhou North to Dalian operating along the newly opened Chaoyang-Linghai high-speed railway in northeast China's Liaoning Province. The 107-kilometer Chaoyang-Linghai high-speed railway which connects Chaoyang and Linghai in Liaoning Province was officially put into operation Tuesday. It allows trains to run at a top speed of 350 kilometers per hour, and greatly shortens the travel time between the Chinese capital of Beijing and some major cities including Dalian and Jinzhou in northeast China.
