These wood-burning Eight-wheelers had two interesting requirements in their specs. One is the very short valve travel (3 1/2"/89 mm), attibutable to its short-stroke setup. The other related to the increasingly likely gauge widening to 4' 8 1/2", specifying "Cylinders to be cast separate from saddle to facilitate changing gauge."
18-19 were sold in 1891 to the Ashley Price Lumber Company of Douglas, Ga, which they served at least until 1906. In 1893, the South Florida went through the gauge modification and 17 and 20 stayed with the railroad as it joined the Savannah Florida & Western Railway. They were off the roster by 1902.
After purchasing the two small wood-burning Eight-wheelers described in Locobase 16256, the South Florida bought an engine ordered in October 1882 for the Thibaud Brothers' Vera Cruz a Alvarado Railway in Mexico. (Locobase 11807 shows an identical engine built for the Hidalgo y Noreste Railway in 1882.) When that order was cancelled, the locomotive was purchased by the SF in April 1883.
Compared to the two earlier 4-4-0s, the 6 had a longer stroke, more heating surface area, and a larger tender. It served the SF until that road converted to standard gauge in 1886. It joined the 4 and 5 on the Orange Belt until 1890, when it was sold north to the Norfolk, Albemarle & Atlantic in Virginia. The NA&A was renamed Norfolk Virginia Beach & Southern in 1896, but the 6 retained its road number. Works number 6660 finally reached Mexico in 1899, when it was sold to Fosburgh Lumber to support logging there.
Locobase at first thought these two Eight-wheeled wood-burners (the second named C H Andrews) borrowed a lot of their design from the Herald, a single small Mogul delivered to the SFRR in 1881 and described in Locobase 16254. Few of the dimensions match, however, and while these are themselves quite small locomotives, they had somewhat more boiler, a non-cubic firebox, and taller drivers.
When the South Florida converted to standard gauge, this pair migrated to the Orange Belt in October 1886 as their #4. Don Hensley wrote that the Orange Belt came into being in the mid-1880s as a result of generous state land grants to narrow-gauge railway builders on Florida's "frontier". AKA The Tarpon Route, the OB Rwy was "one of the last common carrier narrow gauge roads to be built in Florida, which was also one of the last to be converted to standard gauge."
After 1893's business panic, the ailing OB was reorganized as the Sanford & Saint Petersburg in recognition of the long 152 mile (245 km) mainline between the two cities.
When the Plant System bought the S&SP in 1895 and converted it to standard gauge, the 4 was retired. The 5's later career supported southeastern logging companies. Dennis-Simmons Lumber bought it and later sold it to Williamson-Brown Land and Lumber of Cerro Gordo, NC in June 1904. The engine's record acquired a Baldwin "Extra Order" number at this point, which may indicate an overhaul. A year later, W-B sold the 5 to Marion Lumber Company of Marion, SC. (This transaction also attracted an Extra Order number in November 1907.)
