Norfolk Lumber Company 2-6-2 "Prairie" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 13710)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 36. p. 121. (Thanks to Chris Hohl for his 31 December 2014 email giving the tender fuel capacity and his March 2015 email noting Locobase's typographic doubling of that figure. ) Works number was 35506 in November 1910.

After some years on this logging road, the wood-burning (tender capacity of 3 cords) 3 was sold to Camp Manufacturing as their #30
