Stonega Coke & Coal 2-8-0 "Consolidation" Locomotives in the USA
Class Details by Steve Llanso of Sweat House Media
Class 4 (Locobase 11178)
Data from Interstate diagram published on [
] (visited 26 Dec 2004). See also DeGolyer, Volume 25, p. 276. Works number was 22001 in April 1903.
This was very similar to the Interstate Consolidations shown in Locobase 6440 and joined them in 1907. The Stonega line already interconnected with the Interstate and the 1903 specification showed that the tender was lettered "Interstate Railroad". At some point in its long career, the 4 was retrofitted with a set of Southern outside radial valve gear.
Never changing its physical location, the 4 operated on the IRR until 1953.
