Locomotives GSMR had a current operational diesel locomotive roster of seven 4-axle (B-B) units, as any 6-axle (C-C) unit would be too big for the tunnels, and too long for some the line's tight or sharp curves. All of the current units were built by The Electro-Motive Division of General Motors (EMD). GSMR has two
GP9s, Nos. 1751 and 1755, a
GP30 No. 2467, two
GP38-2s Nos. 2668 and 2335, an
F9A No. 4210. GSMR owns one operational
steam locomotive;
S160 2-8-0 "Consolidation" type
No. 1702, which was built by
Baldwin Locomotive Works in September 1942 for the
U.S. Army during
World War II. In 1991, it was purchased by the GSMR, and it operated until 2004, when it was taken out of service, due to firebox issues. Afterwards, the restoration work of No. 1702 began in mid 2014 and completed in late July 2016 with the locomotive reentering excursion service. GSMR also owns another 2-8-0 built by Baldwin,
Southern Railway Ks-1 No. 722, which worked on the former Murphy Branch from 1904 to 1952 and later operated from 1970 to 1980 in the Southern Railway's steam excursion program. The GSMR purchased it in late 2000 and planned to restore it to operating condition by 2026. The locomotive will be converted to burn oil like No. 1702. During 2010, GSMR purchased a third steam locomotive, a former
Swedish State Railways 4-6-0 No. 1149, in
Union City, Tennessee. In 1990, the GSMR considered importing a newly-built
China Railways SY steam locomotive for use in their operations, but for unknown reasons, they never placed an order. In 2020 GSMR retired
GP9 No. 777 and
GP7 No. 711 was retired in early 2022 respectively. The two units were purchased by YouTuber Jimmy Donaldson (better known as
MrBeast), who used No. 777 and No. 711 for a stunt in a later video. The video were uploaded to YouTube in 2022. No. 777 was scrapped soon after the video it was featured in, and No. 711 was left abandoned in a field in Whittier, NC.
