Amtrak’s California Zephyr hustles along the Colorado River under the imposing cliff of Dodge’s Bluff just east of Utaline, Colorado, on June 13, 2009. This former Rio Grande route through beautiful Ruby Canyon is just one of the highlights for passengers riding Amtrak Nos. 5 & 6. Today’s train has original California Zephyr Chicago, Burlington & Quincy dome-observation “Silver Solarium” and former Pennsylvania 10-6 sleeper “Silver Rapids,” which was PRR’s contribution to the “Zephyr pool” of sleepers that originally went through to New York off the CZ at Chicago. Surely the passengers riding in the dome of “Silver Solarium” have the best view through the canyon.
