Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volumes 39, p. 3. Works number was 37161 in November 1911.
Produced as one of a pair (the other going to the Elkin & Alleghany and shown in Locobse 13193), the 10 stayed on the rails to which it was delivered for decades. Only in June 1948 was it sold to the Atlantic & Western of Sanford, NC and renumbered 12. At this point, the 12 was reunited with its production-line companion, which now bore A & W's number 10. Although it was soon retired, the 12 was not scrapped. Rather, it was donated in 1966 to Sanford's Rail House Historical Association, which put it on display.Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 34, p. 132 .Works numbers were 34682-34684 in May 1910.
Consolidations of no special note, this class of engines toiled for the N & S for almost 40 years. They were bought with 1% grades on 60-lb rail in mind.
