Detroit, Toledo & Ironton 2-8-0 "Consolidation" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 100 (Locobase 7864)

Data from DT&I 7-1955 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. 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.

Pletz's account goes into detail about the origins of the DT & I and is a worthy read. (The maps help). When the DT & I was formed out of several mostly bankrupt railroads, the it built new shops at Jackson, Michigan and laid 85 lb/yard (42.5 kg/metre) rail. It also went to Brooks for new power and took delivery of this set of 18 Consolidations.

NB: Superheater area is estimated based on similar installations for which the area is given.


Class 200 (Locobase 5433)

Data from table in January 1917 issue of RME.

A sturdy Consolidation with a relatively big grate for a bituminous coal burner and a sizable superheater fraction as well. The 200s exerted a high tractive effort for a 2-8-0, the steam for which was admitted through generously proportioned 14" piston valves.

The 200 was scrapped in October 1954.
