Copper Range 4-6-0 "Ten-Wheeler" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 51 (Locobase 12361)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 22, p. 139. Works numbers were 17272-17273 in December 1899.

The Copper Range site reports that the 51 was retired in 1922 and sold to Harry P. Bourke, Escanaba, Mi. then later resold to Northwestern Cooperage & Lumber Co of Gladstone.

52 was soon sold to the Pittsburgh & Western as their #252 and came into the Baltimore & Ohio in class B-25 and numbered #286.
