The Trans-Andean railways provide rail transport over the Andes. Several are either planned, built, defunct, or waiting to be restored. They are listed here in order from north to south.
Much of Ecuador's Trans-Andean Railway (a railway network that once ran from Guayaquil to Quito) has been rendered useless by natural disasters. Torrential rains from the 1982-83 and 1997-98 El Niño caused massive landslides that damaged the railway line. The network is operated by Empresa de Ferrocarriles Ecuatorianos. Only three sections remain operational: a 37-mile (59.5 km) segment connecting Quito and Cotopaxi National Park, a 27-mile (43.5 km) stretch between Ibarra and Primer Paso, and the mountainous five-hour, 62-mile (99.8 km) excursion from Riobamba to Sibambe.
Although wholly within Peru, the Ferrocarril Central Andino (FCCA; the former Ferrocarril Central del Perú) running inland from Callao and Lima crosses the Andes watershed at Galera en route to La Oroya and Huancayo. From here the route is extended by the Ferrocarril Huancayo - Huancavelica. In July 2006 FCCA began work to regauge the Huancavelica line from 3 ft (914 mm) to 4 ft 8 1⁄2 in (1,435 mm) (standard gauge). There was also a proposal for a 21 km (13 mi) tunnel under the Andes.
