Kansas, Oklahoma & Gulf 2-10-2 "Santa Fe" Type Locomotives

Class 500 (Locobase 6783)

Data from 1944 KO & G Locomotive Diagrams book supplied in May 2005 by Allen Stanley from his extensive collection.

The KOG's largest engines were these Santa Fes. They had the same grate area as the older Mikes, but had larger boilers. Clearly, the KOG was never a passenger line.
