The EMD GP40X is a 4-axle road switcher diesel-electric locomotive built by General Motors Electro-Motive Division between December 1977 and June 1978. Power for this unit was provided by a turbocharged 16-cylinder EMD 645F engine which could produce 3,500 horsepower (2,610 kw).

Twenty-three examples of this locomotive were built for North American railroads. This unit was a pre-production version meant to test technologies later incorporated into EMD's 50-series locomotives GP50 and SD50. Ten GP40X were delivered with an experimental HT-B truck design that became an option (but never used) on the production GP50.
