Daqin Railway is a state-owned coal rail-transport operator in China. The company's core asset, the Daqin Line, and its 41%-owned Shuohuang Line are China's most important and busiest "west-east coal rail-corridors." The combined volume dominates one third of the coal transported via railways across China. Coal rail-transport contributes more than 80% of Daqin's operating profit. In addition, Daqin also provides passenger rail service in Shanxi province, and hauls bulk goods on a limited scale. China Railway Corporation controls 62% of Daqin.
