As soon as you hear the wheels chugging and see the plume of coal smoke billow into the sky, the time travel commences. With little evidence of modern civilization along many routes, it’s like you’re seeing the landscape just as it existed back in the Old West. And, in a sense, you are. The Cumbres & Toltec Scenic Railroad runs along a railway that was constructed in 1880 to climb the high mountain passages to the silver mining district in southwestern Colorado. Today it operates as one of the United States’ highest railroads, reaching an elevation of more than 10,000 feet. A true relic of the past – and must-see for rail enthusiasts and budding conductors alike. All aboard!
