Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 21, p. 54 Works numbers were 15464 in August 1897.
Essentially identical to the Detroit & Lima Northern delivered a few months earlier (Locobase 16233), this wood-burning Eight-wheeler had smaller drivers, higher boiler pressure, and a larger tender.
Formerly the Gainesville Rocky Point & Micanopy, the G&G emerged in 1895 after reorganization. It was reorganized again as the Tampa & Jacksonville in 1907. A few years later, the locomotive apparently went to locomotive rebuilder/reseller Southern Iron & Equipment for a rebuild, but remained with the T& J. In 1927, the T&J was once again renamed, this time as Gainesville, Rocky Point & Micanopy.
The 100 remained on the road through all of the changes and was only scrapped after the GRP&M was abandoned in 1944.
