Georgia Pine 4-6-0 "Ten-wheeler" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 12239)

Data from Baldwin Locomotive Works datacard as digitized by the DeGolyer Library of Southern Methodist University. Works number was 15469 in August 1897.

Within 4 years of its delivery to the GPR, this small Ten-wheeler went on to the Georgia, Florida & Alabama and later renumbered 121. The GF & A sold the 121 to the locomotive rebuilder/reseller Georgia Car & Locomotive. The GC & L sold the engine to Upchurch Lumber Company (of Jacksonville, Fla) in July 1911. Upchurch operated the #10 for 8 years before selling it to another rebuilder/reseller Birmingham Rail & Locomotive in November 1919 and the BR & L flogged it off to Forest, Mississippi's Bienville Lumber as their #7.
