1879, in order to facilitate the transportation of coal, the Qing government reluctantly agreed to build a railway to Xugezhuang with the help of Li Hongzhang. 188 1 September, the railway from Tangshan to Xugezhuang was repaired about 10 km long. What should I do if I have a railway but no locomotive? So the railway technicians designed and manufactured the steam locomotive themselves. After the locomotive was built, the workers drew two golden dragons on both sides of the locomotive, which were called "dragon" locomotives. Ironically, the train was stopped by a stupid minister in a few days. It turned out that they were afraid that the train would disturb the ancestors of the Qing Dongling, so it was forbidden to call the unknown on the railway, and only mules or horse-drawn coal cars were allowed. Later, people named this railway, which can only use mules or horse-drawn carts, "carriage railway".
