Roberval & Saguenay 2-8-0 Locomotives in Canada
Class Details by Steve Llanso of Sweat House Media
Class unknown (Locobase 6414)
Data from [
], Dr Jonathan Smith's unofficial website for the Boone & Scenic Valley Railroad in Iowa (visited 11 Dec 2004). Dr Smith explains that 17 served the R&S (near Arvida, PQ) until the line closed in 1970. A tourist line -- the Crab Orchard & Egyptian of Marion, IL -- bought it in 1975.
17 seems to have been one of the last used in revenue service in the US. Apparently before the CO&E's shop crew had a chance to prepare it for passenger service, a depot fire in 1977 led to a decision to operate as a freight-only line. Seeing the relatively fresh 2-8-0 in their yard, the CO&E restored it to service without its superheater or feedwater heater.
The BSV bought the 17 in 1987.
