The Rio Grande Zephyr follows the Colorado River near Burns on the Dotsero cut-off on its westbound journey to Salt Lake City in December 1981, behind 5771, 253, 5762 and 5763.
A remnant of the original California Zephyr, this train offered great dining and many as five Vista-Dome cars for viewing the Rocky Mountain Scenery. It was the last train to be replaced by Amtrak.
