The Kansas, Oklahoma and Gulf Railway (reporting mark KOG) (KO&G) was formed on July 31, 1919 from the assets of the bankrupt . The KO&G largely consisted of a single line from Baxter Springs, Kansas, to Denison, Texas, prior to its purchase by Missouri Pacific's Texas and Pacific Railway in 1964 and merger in 1970. The KO&G came under common control of the Muskogee Company (often referred to as the "Muskogee Roads" or the "Muskogee Lines") in 1925, sharing common management with the Midland Valley Railroad and the Oklahoma City-Ada-Atoka Railway from 1930 to 1964.
