The GP39X was an experimental locomotive that was designed to test 50 Series components. Six EMD-owned locomotives were built and in full SOU garb. These units were later converted to GP49 standards. Also, two GP39DC's were produced; the GP39 had an A.C. alternator as standard equipment, however Kennecott ordered two GP39's with D.C. generators.

All GP39-2's are the 12 cylinder 645E engine rated at 2300 horsepower. The various Phases are a railfan designation that refers to the different carbody variations (large vs small radiator, engine moved back thus moving the air intakes and such, the post-80 quieting mods, the GP49 carbodies, etc.).
