Red Nacional de los Ferrocarriles Españoles
Red Nacional de los Ferrocarriles Españoles (RENFE) was a Spanish state-owned company that operated the national Iberian-gauge railway network between 1941 and 2005. For more than six decades and as a monopoly, it was exclusively responsible for the transport of passengers and goods on its lines, as well as for the management of its infrastructure.
