A trio of Richmond Moguls (work numbers 2158-2160) intended for freight work. The design had a the typical pinched first course swelling into full diameter just ahead of the second driven axle. The extended smokebox looked like an afterthought.
Data from DeGolyer, Volume 17, p.110 and SAL 1907 Locomotive Diagrams supplied in August 2013 by Allen Stanley from his extensive Rail Data Exchange. See Locobase 9351 for a description for the elegant diagrams that held the data for these locomotives. Works numbers were 12232-12233 in October 1891.
This pair of Moguls went to the SB RR in the year it completed its main line from Columbia, SC to Savannah, Ga.
When the Florida Central & Peninsular leased the railroad in 1893, it renumbered the pair as 216-217. The SAL later renumbered them 371-372. Their diagram showed a new firebox heating surface area reduced to 124.83 sq ft (9.74 sq m) and a grate area measuring 16.78 sq ft (1.56 sq m). The boiler then held 251 tubes and each was 13" (381 mm) longer. Total evaporative heating surface area now encompassed 1,571.56 sq ft (146.0 sq m).
In July 1917, 371 was sold to Georgia Car & Locomotive for switching duties.

Three years after the FC & P took delivery of a trio of Virginia-made Moguls, they went back to the builder for two more (work numbers 2333-2334). Compared to the earlier locomotives, this duo had smaller boilers and fireboxes, but a little more weight on the drivers.
