Iron Railway 2-6-0 "Mogul" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 12 (Locobase 12562)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 22, p. 86. 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 [link]. Works number was 19720 in November 1901.

When the Iron Railway went back to Baldwin for a Mogul to supplement the 11 (Locobase 12341), it bought a bigger, more powerful version that was the largest of the three 2-6-0s Baldwin would deliver. The cylinder volume increase probably dictated similar growth in heating surface area.

The I Rwy was bought by the Detroit Southern on 25 September 1902 and the 12 was renumbered 65. The DS entered into receivership in 1904 and emerged in 1905 as the Detroit, Toledo & Ironton.

The DT & I eventually rebuilt the 65 as an 0-6-0 switcher and opreated until sometime in the late 1920s.


Class Charles R Batt (Locobase 12341)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 22, p. 86. 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 [link]. Works number was 16642 in April 1899.

The second of three Moguls to be delivered to the Iron Railway by Baldwin significantly changed the ratio between heating surface area and grate area when compared to the John Campbell (#10) of 1894. (Locobase 12139). As a result, the 11's heating surface area to cylinder volume ratio dropped by half.

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

The DT&I later gave the 64 the road number 60. The engine was gone from the rolls by 1930.
