The Datong-Qinhuangdao railway, or the Daqin Line, is one of China's most important coal-transport railway lines. As the need for coal keeps rising this summer, the Daqin Line has been busy transporting coal from Datong City in Shanxi Province to the Qinhuangdao seaport in Hebei Province.

However, continuous heavy rainfall has hit the Daqin Line recently.

Railway workers have since been overhauling the line to ensure safe and efficient operation. More staff members have also been deployed to monitor key operations along the line to ensure safety. Official statistics  in July show the Daqin Line transported nearly 38 million tonnes of coal, up 22 percent year on year. Since the beginning of August, the line has transported more than 22 million tonnes of coal.
