Omaha, Kansas City & Eastern / Quincy, Omaha & Kansas City 4-6-0 "Ten-wheeler" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 500/20/K-8 (Locobase 5470)

Data from a locomotive diagram published on Vernon Beck's website -- http://home.earthlink.net/~vnlbeck/K/ok501.tif (accessed 22 March 2003), a Baldwin Locomotive Works datacard as digitized by the DeGolyer Library of Southern Methodist University, and DeGolyer, Vol 21, p. 79. Works numbers were 15568-15577 in November 1897.

Reflecting their mid 1890s origins, these engines had the older style of dome over the firebox and a coned boiler. On the other hand, the boiler pressure is relatively high.

Itself a product of earlier foreclosures and restructurings, this railroad was reorganized in 1902 as the Quincy, Omaha & Kansas City (CB&Q). All of the Ten-wheelers in this were renumbered at that point.

At least two and possibly all ten of the locomotives were sold by the Burlington to the Chicago & Illinois Midland in 1926. The two that definitely briefly served the C&IM were ex-24 and 25, in class A-2 and enumbered first 5-6, then 505-506. Both were scrapped in 1929. If the other eight did indeed transfer to the C&IM, they were scrapped very shortly thereafter., although the scrapping dates suggest that they never left the QO&KC.


Class K-9 (Locobase 5471)

Data from a locomotive diagram published on Vernon Beck's website -- http://home.earthlink.net/~vnlbeck/K/9.tif (accessed 22 March 2003). According to Corbin & Kerka (1960, p 82), these came from the Jacksonville & St Louis in 1903. Both were retired before 1917.

Fitting right in with the period in which they were built, these light Tenwheelers had the older style of dome over the firebox, small narrow grate, and a coned boiler. The spread between the 2nd and 3rd drivers was almost 4' greater than that between the first and 2nd.
