History Patterson Township, which surrounds Fairmont, began to be settled in 1893, immediately after the opening of the Cherokee Outlet. The Denver, Enid and Gulf Railroad constructed a line through area in 1902. The Enid Right of Way and Townsite Company platted Fairmont on October 18, 1902. A post office was established in December of that year. Previously, residents had received mail at the Luella post office. The Arkansas Valley and Western Railway constructed a branch from Tulsa through Perry and Covington to Steen (northeast of Enid) in 1902–03. The two railroads crossed at Fairmont, making the town a hub of agricultural services. Two elevators were built along the Frisco and two along the Santa Fe.
