Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 39, p. 86. See the rootsweb reprint of Carl Boese, "The Early Days of Jacobson and Hill City" at [] . last accessed 4 February 2012. Works number was 37048 in October 1911.
SRLC laid its logging extension of the Duluth, Mississippi River & Northern in 1899 from Hibbing, Minnesota across the Mesabi Range into the town of Virginia. It was only open for a little more than a decade before it began selling off its property in 1912.
So why did the SRLC buy this Consolidation in 1911? The company continued to exploit part of its former holdings for decades and this engine helped move the timber. It was later sold to A Guthrie.
