The museum says that No. 3170 is likely one of only four SD40 locomotives preserved out of approximately 1,268 built. No. 3170 is powered by a 3,000-horsepower EMD 645-series General Motors engine. The locomotive was built for the Southern Railway in April 1971.
The locomotive made a recent appearance at the North Carolina Transportation Museum in Spencer, N.C., for the Southern Railway Historical Association’s annual conference and National Train Day celebration.
The museum plans to host a formal dedication of the locomotive in the future.
