Oneida & Western 2-8-0 "Consolidation" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 20 (Locobase 14351)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 53, pp. 394+. See also Josetta Griffith (ed), "The Oneida & Western Railroad", Scott County, Tennessee FNB Chronicles, archived on the web at Works numbers were 43529 in June 1916.

Originally conceived as the Jamestown, the railroad that was intended to open up the "Big Survey" adopted a name change to the Oneida & Western in 1913. The Stearns Lumber Company strenuously resisted the construction of this interloping railway and filed in court to stop it. The court agreed that the railroad's promoters did not have a "proper legal right". On the other hand, observed retired Stearns president Frank C Thomas to Griffith, bringing against "a company called the O&W Railroad, that action made it a corporate body and therefore, as of then, it did exist!"

Griffith suggests this as the reason for a 5 August 1913 charter amendment that changed the name from Jamestown Railroad Company to Oneida and Western Railroad Company. By the time the 20 reached the O&W, 15.2 miles of track linked Oneida to Gernt. When it was completed in 1921, the line covered 30 miles with maximum grades of 4% and 20 degree curves (radii of 288 feet/87.8 m).

The O&W sold the 20 to locomotive rebuilder/reseller Birmingham Rail & Locomotive in July 1937. BR&L found a ready buyer in New Jersey's Rahway Valley, which renumbered the engine #15. Twenty-two years later the RV sold the 15 to Nelson Blount, who sold it to the Monadnock Steamtown & Northern Amusement. Ultimately the engine joined many others in the Bellows Falls (later Scranton) Steamtown collections.
