Ride of one of the most spectacular stretches of railroad, the former Rio Grande Moffat Tunnel line. Ride the cab of Amtrak’s California Zephyr and see the entire line from Denver to Glenwood Springs.Part 3 (this part) takes you from Bond, down the Dotsero Cutoff to where you join the original mainline from Pueblo. Then enjoy the ride through Glenwood Canyon. The view is entirely looking ahead.
