California: California Zephyr
The modern California Zephyr is a replacement for a similar train service that ran from 1949 to 1970. The line’s operator, Amtrak, claims that the Zephyr is one of its most scenic journeys, offering views of the Colorado river valley, the Rocky Mountains and the Sierra Nevada. Plenty of people seem to agree, as the California Zephyr transports nearly half a million passengers every year.
