Southern Railway 722 is a Ks-1 class 2-8-0 "Consolidation" type steam locomotive built in September 1904 by the Baldwin Locomotive Works to run on the Murphy Branch, where it hauled freight trains between Asheville and Murphy, North Carolina for the Southern Railway (SOU).

In 1952, it was purchased by the East Tennessee and Western North Carolina Railroad (ET&WNC), alongside its sister locomotive No.

722 and 630 were both traded back to the SOU for use in their steam excursion program until 1980, when they were sent to the Tennessee Valley Railroad Museum (TVRM) in Chattanooga, Tennessee to make way for larger steam locomotives haul the longer and heavier excursion trains.

722 was taken out of service and was eventually purchased by the Great Smoky Mountains Railroad (GSMR) in late 2000, where it is currently being restored to operating condition, anticipated to be completed around 2026.

[1] In the 1920s, it had more upgrades added such as new cylinders and valve assemblies, which allow the locomotive to develop 46,700 lb (21,200 kg) of tractive effort and reclassified again as a "Ks-1" type.

208 and 207, respectively, while their tender coal bunker were cut down to give the engineer a clear view during numerous switching moves and reverse operation.

630) were both traded back to the SOU for use in their steam excursion program in return for a pair of former Central of Georgia ALCO RS-3s.

722 had its firebox repaired and was given a brand new paint scheme of SOU's Virginian green with gold linings to match the fellow excursion locomotive No.

[14][16] In October 1992, Southern's successor, Norfolk Southern (NS) presented the locomotive to the Asheville Chapter of the National Railway Historical Society (NRHS) in Asheville, North Carolina to be on display at the city's Biltmore section.

[16][17] In December 2000, the Great Smoky Mountains Railroad (GSMR), which operates a part of the same Murphy Branch where No.

722 was being disassembled for restoration work, the plans were halted due to GSMR's other steam locomotive ex-U.S. Army No.

1702 went out of service in 2005, leaving them both remaining disassembled outside the GSMR's workshop area in Dillsboro, North Carolina, exposed to the elements.

722 will be converted from burning coal to oil fuel and will eventually retain its 1970s SOU Virginian green excursion paint scheme once the restoration work is finished.
