EMD GP39-2
The EMD GP39-2 is a 4-axle road switcher diesel locomotive built by General Motors Electro-Motive Division between 1974 and 1984. 239 examples of this locomotive were built for American railroads. Part of the EMD Dash 2 line, the GP39-2 was an upgraded GP39. The power for this locomotive was provided by a turbocharged 12-cylinder EMD 645E3 diesel engine, which could produce.
Unlike the original GP39, which sold only 23 examples as railroads preferred the reliable un-turbocharged GP38, the GP39-2 was reasonably successful, ascribed to its better fuel economy relative to the GP38-2 which became of more interest in the 1970s energy-crisis, and to its better performance at altitude.

Rebuilds
Several GP40-2 locomotives were rebuilt by Morrison–Knudsen with head-end power generators, which meant that 1,000 horsepower of the locomotive would go to the generator instead of being used for tractive effort. Because of this, they were renamed the GP39H-2 class of locomotives.Preservation
Only one GP39-2 is preserved as of 2019:- CSX 4317, former Reading Railroad 3413, is preserved at the Reading Company Technical and Historical Society in Pennsylvania. 4317 is the first GP39-2 in preservation.
