What is "terrasur"

The TerraSur is a Chilean Inter-city rail service, opened in 2001 between Santiago and Chillán, on the Chilean Central Valley. It is operated by the Trenes Regionales Terra S.A., a subsidiary of the Empresa de los Ferrocarriles del Estado (EFE). Covering almost 400 km in less than 5 hours, it is the fastest public transportation between those cities.

Currently is the only inter-city service that still operates in the country, and is the fastest rail service in South America, with an operational speed reaching 160 km/h.

Since June 2012, TerraSur has 3 daily services on each direction, between Santiago and Chillán.
