Yellowstone Park Company. Transportation Division

Due to popular pressure, private automobiles were first allowed into Yellowstone National Park beginning on 1 August 1916. Motorized buses would soon replace stage coaches for public transportation in the park. In autumn 1916, Stephen T. Mather, National Park Service Director, conferred with national park concessionaires. The Park Service awarded the Yellowstone Park Transportation Company (YPTCo) an exclusive right to operate public transportation in the Park, beginning in 1917. It began the season with 116 White Motor Company buses. By 1926, YPTCo operated some 350 "yellow buses." The YPTCo fell within the purview of the Yellowstone Park Company, associated with the Park since 1880. In 1980, the United States purchased all of Yellowstone Park Company's assets in the Park and terminated the Company's lease.
