Amtrak train 6, the eastbound California Zephyr, rolls into Glenwood Springs, CO a few minutes before stopping at the depot downtown on a sunny February 1, 2015.
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.
