Travel back to the 1950s for spectacular Denver & Rio Grande narrow gauge action in it final years of revenue service. You'll follow steam freights from Alamosa to Durango, Chama to Alamosa, and through the Black Canyon; move to Marshall Pass where you'll catch the scrap train; enjoy rare scenes of limestone operations at Monarch Pass; watch a portly 2-8-2 "Mike" pull switching duties at the Farmington branch; and more. No excursions here - just hardworking Rio Grande trains earning their keep. Color, 1 hour.
