Silverton, Gladstone & Northerly 2-8-0 "Consolidation" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class Gold Prince (Locobase 12704)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 27, p. 23. See Mark L Evans, "The Silverton Railroads" page of the website at [], last accessed 10 June 2011.. Works number was 24130 in April 1904.

The SG & N was the third of three narrow-gauge railroads to be based in Silverton, Colorado and was the shortest of the 3 at 7.2 miles. Its path up Cement Creek included grades pitched at 5 1/2% and 99 curves of which 5 were wracked into 40-degree contortions. It opened on 2 July 1899.

After operating a couple of small, used Consolidations, the SG & N bought the Gold Prince, which was a much bigger and heavier locomotive.

After the closing of the Kendrick-Gelder smelter in 1908, the railroad went into irreversible decline and was leased in 1910 by Otto Mears, the owner of the other Silverton railroads and bought outright in 1915..

Silverton sold the 34 to the White Pass & Yukon in 1942; the WP & Y renumbered the engine 24.
