Rio Grande Zephyr

The Rio Grande Zephyr was a passenger train operated by Denver and Rio Grande Western Railroad (D&RGW or Rio Grande) between Denver, Colorado and Ogden, Utah. It operated from 1970 until 1983. In operation after the creation of publicly funded Amtrak, the Rio Grande Zephyr was the last privately operated intercity passenger train in the United States.

The train was a remnant of the original California Zephyr, which was jointly operated by the Chicago, Burlington and Quincy Railroad, Denver and Rio Grande Western Railroad, and Western Pacific Railroad. This iteration of the Zephyr ended operations on March 22, 1970, when the Western Pacific discontinued its portion.

The Rio Grande Zephyr commenced operation using the D&RGW's portion of the California Zephyr route from Denver, Colorado to Salt Lake City, Utah. The route was extended to Ogden, Utah to allow for California-bound passengers to connect to the City of San Francisco and later the San Francisco Zephyr, which did not serve Salt Lake City. The Rio Grande Zephyr used mostly the same equipment and staff as was formerly used for the California Zephyr. Since the train was no longer an overnight affair, sleeping cars and a full baggage car were not required. The D&RGW sold their sleepers to the Ferrocarriles Nacionales de México, while their one baggage car was sold to the Algoma Central Railway in Canada.
