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.
|Qty.||Road Numbers||Year Built||Builder||Notes|
|5||500-504||1927||Baldwin||Numbers 500-504 were scrapped by the end of steam on the MP|
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.
