Madrid Atocha (Spanish: Estación de Madrid Atocha, also named Madrid Puerta de Atocha) is the largest railway station in Madrid. It is the primary station serving commuter trains (Cercanías), intercity and regional trains from the south, and the AVE high speed trains from Barcelona (Catalonia) and Seville (Andalusia). These train services are run by the Spanish national rail company, Renfe. The station is in the Atocha neighborhood of the district of Arganzuela. The original facade faces the Plaza del Emperador Carlos V, a site at which a variety of streets converge, including the Calle de Atocha, Paseo del Prado, Paseo de la Infanta Isabel, Avenida de la Ciudad de Barcelona, Calle de Méndez Álvaro, Paseo de las Delicias, Paseo de Santa María de la Cabeza, and Ronda de Atocha.
The Atocha station is really a railway complex, formed by the Madrid Atocha Cercanías and Madrid Puerta de Atocha stations of the Spanish national railways and the Atocha Renfe station of the Madrid underground.
