Atlantic Mining Company 2-8-0 "Consolidation" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class John Stanton (Locobase 12116)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 19, p. 135. Works numbers were 14060 in August 1894 and 16028 in July 1898.

Gene Connelly could find no record of #5's fate - apparently it remained with the AMC for all of its operational life. #6 -- delivered with the name Baltic -- was sold to Charcoal Iron Company of America.

7 went as #8 to the Manistique & Lake Superior; for its subsequent history and a note about conflicting information, see Locobase 8891.
