Madrid Chamartín is the name of the second major railway station in Madrid, Spain. Positioned on the north side of the city, it was built between 1970 and 1975, although subsequent work would be carried on into the early 1980s. At that time it superseded Atocha station, located closer to the city centre. After Atocha itself was rebuilt in 1992, Chamartin lost much of its importance, even though since 2004 it has undergone changes to accommodate the new high-speed line to León.
