The Uintah Railway was a small 3 ft (914 mm) narrow gauge railroad company in Utah and Colorado in the United States. It was constructed to carry Gilsonite which provided most of its operating revenues; but it operated as a common carrier from 1904 to 1939, also carrying passengers, mail, express, and other cargoes including sheep and wool. When a public library was built in Dragon in 1910, the Uintah Railway agreed to deliver library books free of charge to and from any borrower along its route. Many area ranchers and miners took advantage of the opportunity.
