Memorial video for Sandaoling coal mine steam locomotives

The JS series steam locomotives working at Sandaoling coal mine are the last SLs still in active use in China. With the introduction of new diesel engines, they we reassigned to the shunting mission last year and were eventually retired the previous month(Jan. 2023). This video is not made by me and is a temporary solution before the original author uploads the video himself on youtube.
