[1][3][4] However, due to the August 1913 discovery of oil in the Healdton field, being the very area through which the railroad was building, westbound construction on the line was stopped in January 1914 at a location in eastern Jefferson County about one mile north of the existing town of Cornish.

[2][5] The Ringling and Oil Fields Railway (“Oil Fields”) was created as a separate entity on November 23, 1916, under Oklahoma Law, with pretentions of building all the way from the existing Ringling Railroad line north to Oklahoma City.

[6] A detailed snapshot of the Ringling Railroad as of June 30, 1918 showed the operation as a single track, standard gauge steam railway with a 29.981 mainline between Ardmore and Ringling, along with 8.012 miles of yard tracks and sidings, for a total of 37.993 miles.

[8] The AT&SF incorporated a separate subsidiary, the Healdton and Santa Fe Railway Company, in Oklahoma on October 13, 1925, to purchase the properties of both the Ringling Railroad and Oil Fields.

[9] That acquisition was approved by the Interstate Commerce Commission on July 17, 1926, and the Ringling Railroad operated to October 15, 1926.
