Choctaw, Oklahoma and Gulf Railroad

[3][4] In 1902 the CO&G added 20.2 miles to the line, extending it from Tecumseh to Asher, which was a cotton producing area that also experienced a short-lived oil boom starting in the late 1920s.

[3][4][5] This route, served by faithful vintage locomotive Old Beck,[4][6] was among the CO&G assets later acquired by the Rock Island;[3] but, the whole line was abandoned February 10, 1942.

[7] Though not originally controlled by the CO&G, this railway did in the 1901-1902 timeframe build its main line from a connection with the CO&G at Geary, Oklahoma north toward the Oklahoma-Kansas border, about 106 miles distant.

[18] It also built a branch from its line at Ingersoll—a town created by the railroad—west to the Woods County seat of Alva, Oklahoma, about 16 miles.

The Memphis-Amarillo route remained an important main line for the Rock Island, hosting local and transcontinental freight traffic as well as passenger trains such as the Choctaw Rocket from 1940-1964.

Ownership of the Choctaw Route's railway components were split into numerous pieces as a result of the dissolution of the Rock Island Railroad in 1980.

As of 2014, the former Choctaw Route can be described from east to west as: The former Choctaw Route passenger depot in Little Rock, Arkansas, is now a component of the William J. Clinton Presidential Center and Park, though the adjoining historic freight depot was razed as part of the Clinton Center's development.
