For much of the year, the eastbound Zephyr departs Denver after dark. However, in the summer months, there is still a bit of light when it heads east. Here, just days before the official start of summer, the Chicago-bound train is right on time as it passes by Barr Lake, about 18 miles east of Denver 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.
