The Estación de Madrid-Chamartín Clara Campoamor or Madrid Chamartín is the second major railway station in Madrid, Spain. Located on the northern side of the city, it was built between 1970 and 1975, but more work was carried on into the early 1980s. It then superseded Atocha station, which is closer to the city centre. After Atocha itself was rebuilt in 1992, Chamartín lost much of its importance even though since 2004, it has undergone changes to accommodate the new high-speed line to León.
It hosts the railway networks connecting Madrid and north-western Spain, the AVE from Madrid to Segovia, Valladolid and León and many Cercanías lines, as well as the international line to Lisbon. There are also connections with Atocha. Under the railway station is Chamartín Metro Station, linking with lines 1 and 10 of the Madrid Metro, also for travelling to Madrid City Centre.
