The main train station in Madrid is Atocha (Estación de Madrid-Puerta de Atocha). It is the largest railway station in Spain and serves as the primary hub for AVE high-speed trains traveling to southern and eastern destinations like Seville, Malaga, Valencia, and Barcelona. The station is famous for its tropical botanical garden, which covers 4,000 square meters inside the old terminal building and features thousands of plants and a turtle pond. For travelers in 2026, it is important to distinguish between Atocha and Chamartín (Estación de Madrid-Chamartín-Clara Campoamor) in the north, as some high-speed routes to northwestern Spain and certain international connections depart from there. The two stations are connected by a direct tunnel served by Cercanías (commuter) and Metro trains, making transfers relatively straightforward within about 15 minutes.
