Durango and Silverton Narrow Gauge Railroad
Portions of the Alamosa–Durango line survive to this day. The Walsenburg–Alamosa–Antonito line survives as the standard-gauge San Luis and Rio Grande Railroad, with passenger excursion trains service provided by the Rio Grande Scenic Railroad. Two narrow-gauge segments survive as steam railroads, the Antonito–Chama line as the Cumbres and Toltec Scenic Railroad and Durango–Silverton as the Durango and Silverton Narrow Gauge Railroad.
