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. 630, where they were served as switchers around Johnson City and Elizabethton, Tennessee.
In 1967, Nos. 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. In late 1985, No. 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.
