Data from the List and Descriptions of Southern Railway Locomotives 1914 supplied in March 2004 by Allen Stanley from his extensive Rail Data Exchange. These were works numbers 2499-2500 in 1895.
Low-drivered eight-wheelers were bought at about the time the Augusta Southern was created through a 1893 reorganization of the Augusta, Gibson & Sandersville. The main line ran 80 miles between Augusta, Georgia and Sandersville. Procuring the 3 1/2-mile Sandersville & Tennille gave the AS access to the Central of Georgia's Macon-Savannah.
In 1901, the AS came under the control of the Southern Railway, but still operated independently. When the road encountered financial difficulties in 1919, it was acquired by the Georgia & Florida and operated until 1934.
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 18, p 133. Works number was 13166 in December 1893.
This little Eight-wheeler went into service on this little short line. The AS would connect Camden, Ark with Ruston, Louisiana by 1900. By 1906, Dot was too small for the service it performed so the AS RR sold it to the Tremont Lumber Company, which renumbered it 51.
