While Cheyenne, Oklahoma was originally designated as the county seat for Roger Mills County, construction of the nearest railroad into the area, the Clinton and Oklahoma Western Railway terminated in August 1912 at Strong City.

Strong City also grew to become bigger than Cheyenne or any other town in the county, within a year of the railroad's arrival.
