Stearns Salt & Lumber Company 2-6-2 "Prairie" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 13607)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 34, p. 289. Works number was 34343 in February 1910.

This Ludington, Michigan extractive-industries company hedged its bets in exploiting both timber and salt deposits. Justin Stearns was convicted of receiving illegal refunds from the Pere Marquette at the turn into the 20th Century. This setback led him to diversify holdings further and led him to buy timberlands in the South, particularly in Tennessee and Kentucky. It was on one of the roads that hauled out the timbers that this logging Prairie went to work. It would later serve the Bagdad Land and Lumber Company and the Weir Long-Leaf Lumber Ccmpany.
