Duluth & Iron Range 2-8-0 "Consolidation" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class D (Locobase 15910)

Data from the C&EI 6 - 1904 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 2832-2837 in May 1889.

These must not have suited the D&IR's requirements very well because they were sold to the Chicago & Eastern Illinois in April 1892. See Locobase 7129.
