The Dash 8 Series is a line of diesel-electric freight locomotives built by GE Transportation Systems. It replaced the Dash 7 Series in the mid-1980s, and was superseded by the Dash 9 Series for freight usage and the Genesis Series for passenger usage in the mid-1990s. All models of the Dash 8 Series are powered by a 16- or 12-cylinder, turbocharged, GE 7FDL 4-stroke diesel engine.
