The 80 original acres of Greenfield began as the homestead in 1899 of one George Evans. Somewhere in the 1900-1902 timeframe, the Choctaw Northern Railroad built through the area, its line running from Geary, Oklahoma to its termination at Anthony, Kansas. The railroad bought the farm from then-owners T.G. Curtner and J.M. Gray, proceeding to plat the town and sell lots. By 1913, the town had about 300 inhabitants, a newspaper (The Greenfield Hustler), a bank, a lumberyard, two livery barns, two grain elevators, a grist mill, a hotel, an opera house, and various merchants and contractors.
Greenfield still has freight rail service through the AT&L Railroad.
