Chicago, St Paul & Kansas City 4-4-4 "Jubilee" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class M/Motor (Locobase 16226)

Data from CGW 7 1902 Locomotive Diagrams supplied in August 2013 by Allen Stanley from his extensive Rail Data Exchange.

The railroad's shops modified one of its class 80 Eight-wheelers to provide suburban service. The engine was originally delivered by Pittsburgh Locomotive Works to the Wisconsin, Iowa & Nebraska as their #5 and was transferred to the CStPKC in June 1886 when the WI&N was absorbed.

The new owner in turn merged with the Chicago Great Western in 1893, which renumbered the 80 with 3. It was dismantled in 1903.
