Cherry River Boom & Lumber Company 2-6-0 "Mogul" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 8 (Locobase 13896)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volumer 45, p 16. Works number was 40949 in December 1913.

The CRB & LC ceased common carrier operation in 1928, but remained in use as a logging road for decades. The 8 was sold in 1936 to Birmingham Rail & Locomotive, which sold it back to the CRB & LC for scrapping at Richwood.


Class 9 (Locobase 13897)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volumer 53, p 12. (Thanks to Chris Hohl for his 12 January 2017 email noting an improbably low tractive effort that Locobase later traced to the entry of an inaccurate number of cylinders (i.e.1 instead of the usual 2).) Works number was 44502 in December 1916.

A virtual repeat of the #8 that Baldwin delivered in 1913, the 9 used cylinders with 1" greater diameter. After 13 years on the CRB & LC, the 9 took an unusual path away, then back to the CRB & LC. First, the 9 was sold to locomotive rebuilder/reseller Southern Iron & Equipment. SI & E sent it along to another rebuilder/reseller Georgia Car & Locomotive. GC & L sold the engine to Pine Mountain Granite Company of Lithonia, Ga, which gave it #6. After a year, however, PMG sold it back to GC & L, which sold the 6 to yet another rebuilder/reseller, Birmingham Rail & Locomotive. BR & L delivered it back to the CRB & LC, where it regained the number 9.
