Graham County 2-6-2 "Prairie" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class Junaluska (Locobase 13721)

Data from DeGolyer Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 36, p. 165. See also John B Yeach, The History of Railroading in Graham County", archived at http://www.grahamcounty.net/GCHistory/12-railroads/railroads.htm, last accessed 14 January 2012. Works number was 36045 in February 1911.

Bought by the Whiting Manufacturing Company, the Junaluska served the 12.1 miles of line between Robbinsville and Topton, North Carolina. According to the Graham County history website: "On June 5, 1911 Mr. F. S. Whiting and his associates in the Whiting Manufacturing Company purchased stock and proposed an alternate route to the one from Topton through the gap due to the cost of building the road to the gap. He proposed a route from Fontana down the Little Tennessee River on its South Bank, up Meadow Branch across the gap to the Cheoah River and then up the river to Robbinsville."

Yeach adds that such was the financial precariousness of the enterprise, neither route was built for years. In 1923-1924, Champion Paper and Fiber bought up thousands of acres of timberland, a boon that inspired a new look at the GC RR's prospects, Yeach reports: "Mr. H. C. Bemis purchased the outstanding stock of the Graham County Railroad Company, renewed the charter, and started construction of the railroad over the original route from Topton to Robbinsville. The arrival of the first locomotive and cars in Robbinsville in late 1925 was cause for a big celebration by the citizens of the county."
