The locomotives headed main line excursion trains over the entire Southern system until 1978, they were both leased to the Tennessee Valley Railroad Museum (TVRM) in Chattanooga, Tennessee.[4] In 1992, 722 was moved from Southern's successor Norfolk Southern to Asheville, North Carolina to be on display where it had been used in revenue freight service a long time ago.[4]
2000-Present
630, which had been on loan to TVRM, was finally donated to the museum in 1998 by Norfolk Southern.[5] While 722 was purchased by the Great Smoky Mountains Railroad (GSMR) in December 2000.[5] GSMR has plans to restore the locomotive, but it remains disassembled outside their Dillsboro, North Carolina workshop area.[citation needed] In addition, the cost for 722's restoration is $700,000.[6]
