Union Pacific's Moffat Tunnel Subdivision

Union Pacific's Moffat Tunnel Subdivision in Colorado between the west portal of the 6.2 mile-long Moffat Tunnel at Winter Park and Glenwood Springs. Coal trains dominate the scene with plenty of high horsepower diesels on the head-end, middle, and rear. Travel through the depths of Gore Canyon to the lofty heights of the Craig Branch. See why the Rio Grande called this the "scenic line of the world."
