Peace River Phosphate Mining 2-8-0 "Consolidation" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 4 (Locobase 12910)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 28, p. 207. See also how the PRPM was turned into the Charlotte Harbor & Northern in 1907 at Donald R Hensley, Jr "The Boca Grande Route" (, last accessed 22 July 2011). Works number was27256 in January 1906.

This small Consolidation arrived on the PRPM rails in west central Florida just before the management repositioned the business, gained control of the recently chartered Alafia, Manatee & Gulf Coast Railway, and took on the name of Charlotte Harbor & Northern. Obviously well suited to low-speed, light-rail operation up 1 1/2% grades and around 6-degree curves, the 4 served the CH & N for only about a decade before being sold to locomotive rebuilder/reseller Southern Iron & Equipment in 1917.

SI & E's sale to Mayo Lumber co. in May 1918 began a series of moves over the next 10 years to variety of operators. C.H. Grayson Lumber Company bought the engine next and renumbered it # 41. Grayson sold the 41 to another rebuilder/reseller, Georgia Car & Locomotive. GC & L found a buyer in Lake Wales, Fla -- packing crate producer WC Sherman, which renumbered it again as 31. One more time to SI&E, then to Capitola, Fla's Moore Carr Lumber Co in April 1924.
