An EMD GP38-2 is a four-axle diesel-electriclocomotive of theroad switcher type built by General Motors Electro-Motive Division. Part of theEMD Dash 2 line, the GP38-2 was an upgraded version of the earlier GP38. Power was provided by an EMD 645E 16-cylinder engine, which generated 2000 horsepower (1.5 MW).

The GP38-2 differs externally from the earlier GP38 only in minor details. There is a cooling water level sight glass on the right side of the hood, and the battery box covers are bolted down, instead of hinged. It can be distinguished from the contemporary GP39-2 and GP40-2 in that its Roots blown engine had two exhaust stacks, one each side of the dynamic brake fan if fitted, while the turbocharged GP39-2 and GP40-2 has a single stack. The GP39-2 has two radiator fans on the rear of the long hood like the GP38-2, however the GP40-2 has three.

GP38-2W
The GP38-2W is a Canadian variant of the GP38-2. It is easily distinguished by its wide-nose
Canadian comfort cab . 51 of these locomotives were produced forCanadian National Railway during 1973–1974.There are snow-shields above the inertial-filter central air intakes behind the cab; the electrical boxes and equipment blower behind the cab also differ in detail from a standard GP38-2. They are otherwise identical. [cite book

1,801 examples of this locomotive model were built for American railroads and industrials, 257 for Canadian railroads and industrial, 156 for Mexican railroads and industrial and one unit for the Saudi Government Railroad. In addition to these, 20 more examples were built with high
short hood s containing steam generators for use on Mexican railroads. [Marre, Pinkepank - Diesel spotters guide]References
