A 23 km metro is in the very early planning stages for the city of San Francisco de Quito. The work is being done by Madrid Metro. If all goes well and the Mayans were wrong, the completely underground metro will open in 2016.
Also under discussion is the Tren Rapido de Quito, a partially underground light rail line linking the airport with with San Jose and Turubamba. It is yet unknown if the metro will replace the plans for the TRAQ.
