Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 10a, p. 155. Works numbers were 5403 in December 1880 and 5746 in August 1881. See also Mallory Hope Ferrell, Tweetsie Country (1979 and 1991) and John Waite & Chris Ford, The Blue Ridge Stemwinder (2003).
These Moguls were the first two engines to run on the Tweetsie's rails. The ET & WNC, aka the Blue Ridge Stemwinder, was a beloved narrow-gauge line that connected Johnson City, Tennessee with the mountainous portion of North Carolina to the east. Ferrell introduces his account of the Tweetsie by defining the country through which it ran as "...being bounded on the North by the Great Depression, and the east by the state of North Carolna, on the west by Tennessee and on the south by hope and determination."
The Watauga was delivered in time to carry the supplies used to construct the road through the gorge carved by the Doc River. Colonel Thomas E Matson had determined that the only way through this hellacious territory was to allow for 4% grades and 32-degree curves.
The Tweetsie persisted, but the Wautaga was sold to the Linville Railway (which was associated with the Tweetsie) in 1899 and in 1912 to Newell & Bryant. The Cranberry went to the Hilton Lumber Company in 1910.
