Cercanías Madrid

Cercanías Madrid is the commuter rail service that serves Madrid, the capital of Spain, and its metropolitan area. It is operated by Cercanías Renfe, the commuter rail division of RENFE, the former monopoly of rail services in Spain. The system is known for being the target of the 11 March 2004 Madrid train bombings. The total length spans 370 km.

The first railroad line departing from Madrid was built in 1851 between Madrid and Aranjuez. Soon the growing Spanish railway system was dominated by two large companies: the Compañía del Norte , who operated the lines between Madrid and the Atlantic North of Spain from the Estación del Norte ,and the Madrid-Zaragoza-Alicante who operated the lines between the capital and the Mediterranean and Andalusian cities from the Atocha station. Another station, Delicias, served the line to Lisbon. Other smaller companies operated from Madrid, mostly in narrow gauge. After the Civil War, in 1941, the ailing railway companies were nationalised and joined in the new RENFE, and the narrow gauge lines were progressively closed, the last one in 1970. Almost at the same time, the new Chamartín station was built and all services were transferred to the main stations: Chamartín for the north and east-bound and the international services and Atocha for the south and west-bound trains. Both stations were linked by a tunnel, the Connection Railway Line , after a fair attraction very popular in the 1930s.
