Florida Southern 2-6-0 "Mogul" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 22 (Locobase 16423)

Data from "Narrow-Gauge Mogul Locomotive", Railroad Gazette, Volume XV [15] (3 August 1883), p. 509. See Locobase 16422 for a description of the Toledo, Cincinnati & St Louis, which ordered thirteen of this class, but could only take delivery of five. Works numbers were 901-902 in April 1883.

As explained in Locobase 16422, eight of the wood-burning narrow-gauge Moguls from the Dunkirk, NY builder were either diverted before delivery or quickly sold back and appear under the railroads that bought them from either E B Phillips or Brooks.

These Moguls were bought by a new narrow-gauge line in central Florida that was established in 1879 as the Gainesville, Ocala & Charlotte Harbor. Renamed Florida Southern in 1881, the Orange Belt Route's main line ran south-southeast from Gainesville through Ocala and Leesburg to Pemberton's Landing. Later extensions to Lane Park and Astor created a backward J.
