Renfe (Red Nacional de los Ferrocarriles Españoles) is the state-owned national railway company of Spain. It operates the majority of the country's passenger and freight rail services, ranging from local commuter trains known as Cercanías to the world-famous AVE (Alta Velocidad Española) high-speed trains. The AVE network is one of the most advanced in the world, connecting major cities like Madrid, Barcelona, Seville, and Valencia at speeds of up to 310 km/h (193 mph). Renfe also manages Avant (mid-distance high-speed) and Alvia (trains that can travel on both high-speed and traditional tracks) services. In 2026, while the Spanish rail market has opened to competition from private operators like Ouigo and Iryo, Renfe remains the dominant carrier, offering a vast network that reaches nearly every corner of the Iberian Peninsula. For travelers, Renfe is the primary way to navigate Spain comfortably without a car, offering various classes of service and a reliable, frequent timetable.
