Cherokee Saw Mill Company / Florida Central 2-6-0 "Mogul" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 20 (Locobase 13229)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 31, p. Works numbers were 32234-32235 in November 1907.

This pair of logging Moguls had the same boiler and grate as several other Baldwin products in the same period, but more cylinder volume. The larger cylinders more than compensated for the slightly taller drivers in providing starting tractive effort. J L Philips, the company that paid for the engine, ordered a pair for two different parts of its Florida Holdings.

The Cherokee Saw Mill 20 went to Caldwell Lumber, which later sold it to Long Paisley Lumber Company.

The Florida Central #100 was absorbed by the Atlantic Coast Line in February 1915 and renumbered 600. After five more years, the ACL sold the engine to North Carolina shortline Wilmington, Brunswick & Southern. The WB & S traded the 600 for another in locomotive rebuilder/reseller Georgia Car & Locomotive's inventory. GC & L passed it on to fellow rebuilder Birmingham Rail & Locomotive and they sold it to JM Griffin Lumber Company of Holopaw, Fla in July 1924 as their #5. Ultimately, the 5 went to Peavy Wilson Lumber Company.
