The DF8 (Chinese: 东风8) is a type of diesel-electric locomotive used by China Railway in the People's Republic of China. It was in production from 1984 until mid-1990s, with mass production starting in 1989. The revised DF8B is still in production today. DF8 are almost exclusively used for freight services.
