Trains operated by Chile's national railway company, Empresa de los Ferrocarriles del Estado (EFE), connect Santiago to several cities in the south-central part of the country: Rancagua, San Fernando, Talca (connected to the coastal city of Constitución by a different train service), Linares and Chillán. All such trains arrive and depart from the Estación Central railway station (Central Station), which can be accessed by bus or subway. The proposed Santiago–Valparaíso railway line would connect Santiago with Valparaíso in 45 minutes, and expansions of the commuter rail network to Melipilla and Batuco are under discussion.
