The Cumbres & Toltec Scenic Railroad, often abbreviated as C&TSRR, is a 3 ft (914 mm) narrow-gauge heritage railroad running for 64 miles (103 km) between Antonito, Colorado and Chama, New Mexico, United States. The railroad gets its name from two geographical features along the route, the 10,015-foot (3,053 m)-high Cumbres Pass and the Toltec Gorge. Originally part of the Denver and Rio Grande Western Railroad's narrow-gauge network, the line has been jointly owned by the states of Colorado and New Mexico since 1970.
