The Cumbres & Toltec Scenic Railroad (C&TS) is a 3 ft (914 mm) narrow gauge heritage railroad running between Chama, New Mexico and Antonito, Colorado. It runs over 10,015 ft (3,053 m) Cumbres Pass and through Toltec Gorge, from which it takes its name. Trains operate from both endpoints and meet at the midpoint. Today, the railroad is the highest and longest narrow gauge steam railroad in the United States with a track length of 64 miles. The train traverses the border between Colorado and New Mexico, crossing back and forth between the two states 11 times. 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. The Cumbres & Toltec Scenic Railroad received the Designation of a National Historic Landmark in 2012 by the United States National Park Service.
