Sapulpa and Oil Field Railroad

The Sapulpa and Oil Field Railroad (S&OF) was a shortline railway which was constructed by 1915 or 1916 from the oil boomtown of Depew, Oklahoma to the newer boomtown of Shamrock, Oklahoma, about 9 miles.^[1][2][3] Despite the name, the line never came close to the city of Sapulpa, Oklahoma, which was far to the northeast.^[4]

Depew already had rail service from the St. Louis-San Francisco Railway (Frisco).^[1] But when the S&OF bypassed Shamrock by three-quarters of a mile, the arrival of that railroad was important enough that the townspeople of Shamrock relocated their establishments to the southeast to be closer to the tracks.^[2] The railway carried both passengers and freight traffic related to development of the Shamrock oil field.^[3]

The Frisco acquired the railroad and began operating it effective July 1, 1917.^[3] Shamrock began declining in the mid-1920's when oil production shifted to other areas, and the site is now considered a ghost town.^[5] The rail line was abandoned in October 1957.^[2]
