A Cumbres & Toltec Scenic (C&TS) Railroad steam train climbs from the high desert around Antonito in Conejos County, Colorado, near the New Mexico border into the San Juan Range of the Rocky Mountains. The C&TS is a three-foot narrow gauge heritage railroad running between Chama, New Mexico and Antonito. It runs over 10,015-foot Cumbres Pass and through Toltec Gorge, from which it takes its name. As of 2015, the railroad was the highest and longest narrow-gauge steam railroad in the United States, with a track length of 64 miles. The train crosses back and forth between the two states 11 times when it makes its full journey. The Cumbres & Toltec Scenic Railroad has been jointly owned by the states of Colorado and New Mexico since 1970 when it was purchased from the Denver and Rio Grande Western Railway, saving it from the scrap yards.
