High Quality Content by WIKIPEDIA articles! The Cumbres & Toltec Scenic Railroad (C&TS) is a narrow gauge heritage railroad running between Chama, New Mexico and Antonito, Colorado. It runs over the 10,015 ft (3,053 m) Cumbres Pass, the highest point on a US passenger railway. The track was originally laid in 1880 by the Denver and Rio Grande Railroad. In 1970 the C&TS began to take tourists on six-hour trips between the two towns, using steam locomotives.
