The Millen & Southwestern short line linked Millen and Stillmore over a 53-mile stretch in Georgia. These two Ten-wheelers had a note included in their specs that reflects the exigencies of a marginal operation: "Be very careful not to overrun weight on drivers on account of very light rail. Guaranteed to haul 270 to 280 tons of 2240 lbs up a straight grade of 2%, cars and track in good condition." The specs added that there should be enough metal in the cylinders to allow them to be bored out to 18".
The M & SW was merged with several other roads into John Skelton Williams' Georgia & Florida Railway system in 1906. The order of road numbers reversed for some reason when the G & F assigned 15 and 14 respectively; they were later renumbered 151, 150. 150 was sold to the 3-mile Sandersville Railroad in May 1934 while 151 went to the Milstead Railroad, an industrial short line also in Georgia, in November 1935.

(Thanks to Chris Hohl for his 7 April 2015 email noting an improbably high value for the tender's coal capacity.) Works numbers were 24997, 25021 in January 1905.
This batch was one of several featuring light Ten-wheelers with identical boilers. Another order featuring the larger firebox shown in this one was Pennsylvania's Bloomberg & Sullivan engines described in Locobase 12748.
When the Georgia & Florida was formed by combining the M&SW with five other Georgia shortlines in 1906, the G & F renumbered these two Ten-wheelers as 130-131. 130 was sold in 1922 to the Tampa & Jacksonville (later Jacksonville Gainesville & Gulf) as their 70. It was scrapped in August 1932. Also in 1922, the G & F sold the 131 to locomotive rebuilder/reseller Southern Iron & Equipment. SI & E found a buyer in Ruston, Louisiana-based Wyatt Lumber only a few months later.

John Skelton Williams formed the Georgia & Florida Railway system in 1906. According to the Rail Georgia site ([]) the six smaller railroads that were amalgamated were:
Name Connecting Miles
Augusta & Florida Railway Keysville-Midville) 30
Atlantic & Gulf Short Line Railroad Midville-Swainsboro 20
Douglas, Augusta & Gulf Railway Hazlehurst-Nashville 87
Barrows Bluff-Broxton
Millen & Southwestern Millen-Stillmore 53
Nashville & Sparks Railway Nashville-Sparks 12
Valdosta Southern Railway Valdosta-Madison, Fla 28
Williams later built three connecting segments that created a single mainline south from Augusta to Madison, Fla., acquired trackage rights to the Keysville-Augusta section of the Augusta Southern, acquired the Sparks-Western Railway, the Augusta Southern itself, and leased the Midland.
By 1930, the slow dissolution of the Williams system had begun and would slowly take hold until the Southern bought the remaining segments in 1963.
All but one of these low-drivered Ten-wheelers served the G & F throughout their careers. The specifications pages record 1916 correspondence between G & F and Baldwin concerning frame cracks. The resolution appears to have been that the frames would be made heavier.
51 was scrapped in 1951, 52-57 in February 1955. 50 was sold in August 1937 to Apalachicola Northern as their 151.
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 28 Vol 34, p. 144, 146.. Works number was 27098 in December 1905.
Not long after the 30-mile A & F took delivery of the 6 from Baldwin, John Skelton Williams's Georgia & Florida absorbed the road; see Locobase 12754 for a summary of this consolidated line. In the amalgamation, the 6 became the #10.
Not willing (or perhaps wealthy enough) to discard locomotives, the G & F kept this small, wood-burning Ten-wheeler in service for decades. It was scrapped in December 1950.
