Amtrak #69 is on point as the California Zephyr drops down out of Tunnel #1 at Plainview and heads towards Coal Creek Canyon. It will then take another 45 minutes to get to Denver's downtown Union Station.
Two Amtrak routes serve the Centennial State. The California Zephyr's route through Moffat Tunnel and along the Colorado River goes from one end of the state to the other. The Southwest Chief cuts across the southeast corner.
