J L Greer 2-6-0 "Mogul" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 22 (Locobase 13820)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 39, p. 53. For more on "deadhead logging", see "What is Deadhead Logging? on the Florida Department of Environmental Protection website at [link]; "Deadhead Logging - Frequently Asked Questions" at [link]; and a description of how Bruner Lumber Company recovers those "big sinkers" at [link]; all last accessed 27 May 2024. Works number was 37378 in December 1912.

(NB: About 10% of the old-growth cypress and longleaf pine trees felled in the late 1800s in to the 1900s were lost off river transport and sank to the bottom. See the sources referenced above for the recent decades' development of "big sinker" recovery.)

Richland, Florida's J L Greer Lumber company bought this logging Prairie. Although it changed owners three times, the 22 never changed its number. It's likely that the moves related to exhausting the cypress groves and longleaf pine stands one by one. Richland lies about 40 miles (64 km) northeast of Tampa. At some point, the engines moved about 30 miles west to J H Dowling Lumber in Odessa. Still later, the 22 traveled 120 miles north to Gulf Hammock and Patterson Lumber. For its final job, the 22 headed 420 miles down the peninsula to C J Jones Lumber based in Jerome, located southeast of Naples and 85 miles west of Miami.
