Beginning service in 1949, the original California Zephyr operated over the Chicago, Burlington and Quincy Railroad from Chicago to Denver, the Denver and Rio Grande Western Railroad between Denver and Salt Lake City, and the Western Pacific Railroad from Salt Lake City to Oakland. In summer 1954 the schedule for 2,532 miles between Chicago to San Francisco was 50hr 50min. The Budd Company manufactured six ten-car trainsets; the California Zephyr was the first long-distance train to carry domes in regular service. Passenger train revenue began to fail in the 1960s and Amtrak eventually revived the Zephyr in the 1970s.

The Moffat Tunnel cuts through the Continental Divide in north-central Colorado at 9,239 feet. Named after Colorado railroad pioneer David Moffat, the tunnel's first railroad traffic passed through in February 1928.
