SY 1018 departs Lijing mine

I nearly didn't get this shot. I had walked a considerable distance up the branch to the Lijing Mine on the Hengshan system of the Jixi coal railway. A few minutes earlier I had changed lenses and had not noticed that a small sealing ring had become partly detached. Shortly afterwards the loose ring stated to foul the mirror when it swung clear and the camera ceased to function. Detecting the fault and fixing it in the freezing temperatures induced mild panic as the train was about to set off. The spare camera was over a mile away in the minibus. Luckily I was able to sort it all out just as things started to move. I wonder what happened to the chimney on the locomotive?
