Minnesota, Dakota & Western 2-8-0 "Consolidation" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 101 (Locobase 14092)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 46, p. 300. See also the Thursdaynighthikes history of Minnesota Railroads II at [] . Works numbers were 39393 in March 1913 and 44500 in December 1916.

Organized as the International Bridge & Terminal Company in 1902, this railroad gained its better-known initials in 1910 when E W Backus sought to connect some planned flour mills in International Falls, Minn, with Dakota wheat from the Pembina, North Dakota area. Moody's Manual of 1918 still carries a note that "It is proposed to construct 200 miles of line, extending from International Falls to various points in Minnesota."

But the mills weren't built and the railroad never grew beyond 44 miles. Moody's shows the line extending 22 miles to Loman, Minn, 3.3 miles from International Falls to Falls Junction, and the original IBT&C line from Fort Francis, Ontario and International Falls.
