Copper Range 2-8-0 "Consolidation" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class C-3S (Locobase 4842)

Data from, accessed 22 July 2007, is the source for the dates of construction -- 58278-58279 in December 1917 -- and their fates - both sold for scrap in March 1947. (Many thanks to Nicholas Turinetti for his 20 May 2014 querying the driver diameter and persuading me to revise the number.)

The CRRR ran in the Upper Peninsula of Michigan and these were the "Big Boys" of the railroad, according to Kevin E. Musser of the Copper Range website. These ran for 30 years after which they were sold for scrap.
