Detroit, Toledo & Ironton 2-8-0 "Consolidation" Type Locomotives

Class 100 (Locobase 7864)

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

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.
