Kanawha & Ohio 2-6-0 "Mogul" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 90/290 (Locobase 15976)

Data from AT&SF 9 -1920 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. See also DeGolyer, Volume 13, p. 125. Works numbers were 8219, 8221-8223 in October 1886, 8225-8226 in November.

Locobase 8900 shows the ten locomotives of a sixteen-engine order that were delivered as planned to the Gulf, Colorado & Santa Fe. The other six were sold before delivery to the K&O. In April 1890, the Kanawha & Ohio's 132 miles was reorganized as the Kanawha & Michigan and this Mogul sextet was renumbered 290-295.
