Datong–Qinhuangdao railway
Datong–Qinhuangdao railway or Daqin railway (simplified Chinese: 大秦铁路; traditional Chinese: 大秦鐵路; pinyin: Dàqín tiělù), also known as the Daqin line (simplified Chinese: 大秦线; traditional Chinese: 大秦線; pinyin: Dàqín xiàn), is a 653 km coal-transport railway in north China. Its name is derived from its two terminal cities, Datong, a coal mining center in Shanxi province, and Qinhuangdao in Hebei province, on the Bohai Sea.

Daqin railway carries over 1/5th of the coal transported by rail in China, more coal than any other railway line in China and the world.[1]
The line was constructed in two phases between December 1984 and December 1992, with specifications changed from single-track to double-track during construction.[2] Design capacity was 100 million tonnes a year, which it reached after ten years, but continuous upgrades (wider subgrade, 75 kg/m rails, wagons with higher capacity and top speed, longer trains and stronger locomotives, radio operation and centralised traffic control, automatic train inspection) quadrupled capacity.[3]
In 2006, powerful locomotive models HXD1 and HXD2, with 9.6 MW and 10 MW power output respectively, entered Daqin line to replace the older DJ1 models.
