Denver and Rio Grande Train Silverton, Colorado ...

The Durango and Silverton Narrow Gauge Railroad (D&SNG) is a narrow gauge heritage railroad that operates 45 miles (72 km) of 36-inch (914 mm) track between Durango and Silverton, in the US state of Colorado. The railway is a federally designated National Historic Landmark and is also designated by the American Society of Civil Engineers as a Historic Civil Engineering Landmark.

The route was originally built between 1881 and 1882, by the Denver and Rio Grande Railroad, in order to carry supplies and people to and silver and gold ore from mines in the San Juan Mountains. The line was an extension of the D&RG narrow gauge from Antonito, Colorado to Durango. The Cumbres and Toltec Scenic Railroad operates the line from Antonito to Chama, New Mexico. The line from Chama to Durango has been abandoned and removed.

The line from Durango to Silverton, however, has run continuously since 1881, although it is now a tourist and heritage line hauling passengers, and is one of the few places in the United States which has seen continuous use of steam locomotives.
In March 1981, the Denver & Rio Grande Western sold the line and the D&SNG was formed.

Some of the rolling stock dates back to the 1880s. The trains run from Durango to the Cascade Wye in the winter months and run from Durango to Silverton during the summer months. The depot in Durango was built in January 1882 and has been preserved in original form.
