The ''Instituto Costarricense de Ferrocarriles'', or the state owned railway institute, is in charge of all of Costa Rica's railways. In 2004, this institution began work on the establishment of an inter-urban railway network. This network would connect Tibás, Heredia, San Antonio de Belén, Pavas, San Pedro de Montes de Oca, Sabanilla, and Curridabat, among other locations.
