Kansas, Oklahoma & Gulf 2-10-2 "Santa Fe" Locomotives in the USA
The KO&G owed much of its latter existence to its status as a bridge line between the Missouri Pacific at Okay, Oklahoma and the Missouri Pacific-controlled Texas and Pacific Railway at Denison, Texas. This traffic was the main source of revenue for the KO&G and was the primary reason that the Missouri Pacific's Texas and Pacific Railway acquired it in 1964.
The Kansas, Oklahoma & Gulf bought five "Santa Fe" type locomotives in 1927 from the Baldwin Locomotive Works. These locomotives carried road numbers 500 through 504 and had 63" diameter drivers, 27" x 30" cylinders, a 200 psi boiler pressure, they exerted 59,014 pounds of tractive effort and each weighed 330,000 pounds.
There are no surviving KO&G 2-10-2 "Santa Fe" type locomotives.

Class Details by Steve Llanso of Sweat House Media
Class 500 (Locobase 6783)
Data from 1944 KO & G Locomotive Diagrams book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange and DeGolyer, Vol 77, pp. 634+. (Thanks to Chris Hohl for supplying the tender capacity.) A summary of the Muskogee Company empire appears in the Muskogee Company records, DeGolyer Library, Southern Methodist University, [
], last accessed 26 April 2015.
Works numbers were 60128-60132 in August 1927.
The Muskogee Company's KOG's largest engines were these Santa Fes. They had the same grate area as the older Mikes, but had larger boilers. A combustion chamber added 89 sq ft (8.25 sq m) to the firebox's heating surface area. Clearly, the KOG was never a passenger line.
