The EMD GP39-2 is a 4-axle 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 2,300 horsepower (1,720 kW).
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.[1]
Original owners
The GP39-2 sold to five railroads and two industrial operators:[2]
| Railroad | Quantity | Road numbers | Notes |
|---|---|---|---|
| Atchison, Topeka and Santa Fe Railway | 106 | 3600–3705 | Remainder to BNSF; 3600-3616 sold to Willamette & Pacific Railroad in 1993. |
| Burlington Northern Railroad | 40 | 2700–2739 | All to BNSF |
| Kennecott Utah Copper Corporation | 32 | 1-3, 705–711, 779–799, 905 | 705-711 and 779-799 were built with raised cab roofs and extra windows for improved visibility in the Bingham open pit copper mine. Kennecott #3 was built for the Ray Mines Division of Kennecott Copper Corporation |
| Missouri–Kansas–Texas Railroad | 20 | 360–379 | 371 to UP as 2370, then to NEGS, then to WAMX as 3927, operating with AA |
| Phelps Dodge Corporation | 1 | 33 | |
| Reading Company | 20 | 3401–3420 | To Delaware and Hudson Railway, Chessie System, and then to CSX[citation needed] |
| Total | 239 |
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 GP38H-2 class of locomotives.[citation needed]
Preservation
Only one GP39-2 is preserved as of 2019:
- CSX 4317, former Reading Company 3412, is preserved at the Reading Company Technical and Historical Society in Hamburg Pennsylvania. 4317 is the first GP39-2 in preservation.
