Alexander & Rich Mountain 2-8-0 "Consolidation" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 6 (Locobase 12178)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 20, p. 71. Works number was 14625 in January 1896.

The A & RM had converted to standard gauge by the time they bought this small Consolidation, which wouldn't have looked out of place on the 3-foot line they had just replaced. It was, in fact, one of the smallest 2-8-0s produced for the standard gauge in any country, so Locobase suspects that it was originally intended for the skinny rail.

Transforming into the Alexander & Eastern in 1906, this West Virginia railroad operated the 6 until August 1910, when they sold it to the newly opened Croft Railroad. At the time of incorporation, the CR was reported to plan a road "...from a point near Alexander in Upshur County to or near the Zenders farm in the same county ..."

The CR sold the 6 to F C Cooke, still of Alexander, in 1925.
