 As of 2004, the denominated "Tren Interurbano" was reestablished to run services between neighboring cities Heredia and San José (due to the conurbation phenomenon, both cities and in minor extent Alajuela and Cartago, became part of one same urban area known as GAM, Gran Area Metropolitana, Great Metropolitan Area) as well as between Pavas and San Pedro neighborhoods in San José.New Apolo engines imported from Spain should start servicing the route San José - Heredia, several times a day, by the end of April 2009.This transport alternative has received relative widespread acceptance from citizens in GAM to the point that the Government will bid (third quarter, 2009) for the construction and operation of a modern system to operate between Heredia - San José, and San Pedro - Sabana Sur on an initial stage.
