After the Twin Zephyrs and the Colorado Eagle, the next great–some would say the greatest–domeliner to hit the rails was the California Zephyr. This train followed the route of the Exposition Flyer, a train that began running in 1939, the year of the Golden Gate International Exposition, after which the train was named.
The Flyer was operated by three railroads: the Burlington from Chicago to Denver; the Denver & Rio Grande Western from Denver to Salt Lake City; and the Western Pacific from Salt Lake City to Oakland. The Rio Grande and Western Pacific had a shared history, as the latter was financed and built by the former when it was under the control of George Gould.
