Desloge Consolidated Lead Company 2-6-0 "Mogul" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 16 (Locobase 13702)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 36, pp. 67. See also Bill Earngey, Missouri Roadsides: A Traveler's Companion (Columbia, MO: U of Missouri Press, 1995), p. 76. Works number was 35565 in October 1910.

After suffering a disastrous fire in 1887 at its St Francois County mill, the Desloge company merged with the St Joseph Lead Company of Bonne Terre and, in 1890, the Mine A Joe Company and the St Francois Lead Mining Company. Their headquarters was in Slab Town, which lay to the west of the St Louis, Iron Mountain & Southern; Slab Town would be renamed Desloge by 1912.

This Mogul had the slope-backed tender that usually meant switching operations and appears to have operated its entire career for Desloge.
