Detroit Southern / Iron Railway 4-6-0 "Ten-Wheeler" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 80 (Locobase 12342)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 24, p. 264. Works numbers were 23440, 23452 in December 1912; 23517 and 23566-23567 in January 1904.

The December engines were originally intended for the Chicago, Cincinnati & Louisville, but were diverted to the Detroit Southern.


Class 85 (Locobase 12343)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 27, p. 194. Works numbers were 25036-25037 in January 1905 and 25080 in February.

These were duplicates of the earlier batch of five shown in Locobase 12342 rolling on smaller drivers in a purely freight role. Like the others, they retained their road numbers when the DS was reorganized as the Detroit, Toledo & Ironton in 1905.


Class John Campbell (Locobase 12139)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 19, p. 200. Works number was 14206 in January 1895. See also William C Pletz, "The Railroad That Went No Place (but eventually made it)", Ann Arbor Train & Trolley Watchers, 1979 as hosted on the Michigan Railroads site at http://www.michiganrailroads.com/RRHX/Stories/DT&I-TheRailroadThatWentNoPlacePart1.htm.

The I Rwy was taken up by the Detroit Southern on 25 September 1902, when the engine was renumbered as 64 . After the DS entered receivership in 1904, the line emerged in 1905 as the Detroit, Toledo & Ironton.
