The China Railways SN class was a series of 0-10-0 tender locomotives built by Baldwin Locomotive Works for the Gebishi Railway, transporting passengers and goods between Gejiu City and Shiping County. The locomotives served on this line until its closure in 1990.

At least three members of the class are known to be preserved. No.23 is currently displayed in the China Railway Museum, while No.26 is in the Shanghai Railway Museum,[4] No.29 is in the Yunnan Railway Museum.[5]
