Data from Baldwin Locomotive Works datacard as digitized by the DeGolyer Library of Southern Methodist University. Works number was 15469 in August 1897.
The short-lived Georgia Pine Railway ordered this wood-burning Ten-wheeler as the first road engine. The GPR, whose founder, John P Williams of Savannah, gained its charter in 1895, built 29 miles (50 km) connecting Bainbridge with Damascus, Georgia to the north and extended the line further north to Arlington another 10 miles (16 km) away.
In 1901, the GPR became the Georgia, Florida & Alabama, which renumbered the 1 as 121 and took advantage of the engine's light weight to run it on the Quincy branch. The GF&A sold the 121 to the locomotive rebuilder/reseller Georgia Car & Locomotive.
GC&L sold the engine to Upchurch Lumber Company (of Jacksonville, Fla) in July 1911. Upchurch operated the #10 for eight 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.
