The Durango–Silverton train was built to haul ore, not tourists

The train that climbs from Durango up to Silverton is one of the most recognizable things in the county, but it did not start as a sightseeing ride. The narrow-gauge line was built in the early 1880s for a practical reason: to carry ore down from the Silverton mining district to smelters in Durango, and to bring supplies and people back up to a town that snow could otherwise cut off.

“Narrow gauge” means the rails sit closer together than on a standard railroad. That choice let builders thread a slender railbed along ledges through the deep, narrow Animas River canyon, where a wider line would have been far harder to build. The route is part of why the railroad is remembered as an engineering feat of its time.

Today the Durango–Silverton segment is a National Historic Landmark, the highest level of historic recognition the federal government gives, and it still operates as a working railroad in the warmer months. For anyone living nearby, it is a reminder that the county’s roads, rails, and towns were all shaped first by moving rock.

For a careful, sourced history of the line and its landmark status, the National Park Service and History Colorado are good starting points rather than tourist retellings.
