Amtrak #198 brings #5, the California Zephyr, slowly through Byers Canyon, Colorado. This is on the Union Pacific's Moffat Tunnel Sub. The loose rock on the steep slopes here require near continuous slide fence protection.
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.
