The Valparaíso Metro (formerly called "Merval") is the commuter rail system serving the urban conglomeration of Gran Valparaíso; it consists of one line, long, serving 20 stations, that connects Viña del Mar with the neighboring cities of Valparaíso, Quilpué, Villa Alemana and Limache. It passes through Viña del Mar in a underground stretch (from Miramar through Chorrillos stations) opened in 2005, after major upgrade works on the line.
