PROTOTYPE SPECIFIC INFORMATION
Built in November 1980, Southern Railway’s six GP39X locomotives were built during a time a transition for EMD–from the Dash-2 series, to the 50-series. These 2,600hp units, powered by a 12-cylinder 645F3 prime mover, were essentially test beds (hence the “X” in their designation) for future medium-horsepower locomotives that would be part of the forthcoming 50-series. While resembling Phase I GP50s at first glance … “tapered” sidesills, “pointed” anticlimbers, rounded blower housing, and tall radiator intakes … these units had only a pair of 48” “Q-Fans” for radiator cooling, as well as revised clean air compartment and engine compartment layouts, in deference to their shorter 12-cylinder prime mover (vs. the 16-cylinder version used in the GP50).

Keeping with Southern Railway practice, these units, numbered 4600-4605, were equipped with 81” tall high short hoods, control stands set up for long-hood forward operation, bell on the long hood end, dual Nathan 5-chime horns, snowplows fore and aft, and walkway safety lights mounted to the long hood, dynamic brake housing, and high short hood.

In 1982, these six units were returned to EMD’s La Grange, Illinois plant for internal mechanical modifications and upgrades, essentially making them “true” GP49s, the medium-horsepower unit EMD cataloged as part of the 50-series. Their horsepower was raised to 2,800hp as a result, and their designation was officially changed to GP49 as well.

As medium-horsepower units, they could be found in a variety of service, from locals to mainline freights. They would continue on in service for Southern Railway’s successor, Norfolk Southern, gaining a coat of “Thoroughbred” black paint in the process, and remaining on their active roster into the early 2000s.
