Oklahoma-Southwestern Railway

Slick, the OSR was intended to service Oklahoma oilfields, and was originally projected to run about 50 miles from Bristow to Okmulgee, then an active refining center.

[1][2] Starting from a connection with the St. Louis-San Francisco Railway at Bristow and heading generally southeast,[2][3] the line was built in 1920 through the Bristow oil field to Slick, Oklahoma, about 12 miles,[1][4] where a large depot was constructed to handle the crowds that flocked to Slick to "get rich from the gushing black gold.

Production of oil began to decline in the latter part of 1923, and other methods of transportation, such as pipelines and motor vehicles, eventually took half the cargo the railway might have carried.

[2] By 1929, the railroad was losing money, and passenger service was down to one mixed train doing a round trip three times a week.

[2] The Interstate Commerce Commission authorized abandonment of the line on December 21, 1929.
