The only surviving locomotive of the narrow gauge East Tennessee and Western North Carolina Railroad (ET&WNC) is No. 12, a coal-fired 4-6-0 built in 1917 by the Baldwin Locomotive Works. It was originally used to haul passengers and freight over the ET&WNC's line running from Johnson City over the Appalachian Mountains to Boone, North Carolina from 1918 to 1940. Since 1957, it has been in operation at the Tweetsie Railroad theme park in Blowing Rock, North Carolina.
