DESCRIPTION
Madrid metro network is one of the longest in Europe, with a remarkable growth in the last years.
The first line (Line 1) opened in in 1919 (Cuatro Caminos-Sol) and it was extended in 1921, 1923, 1929, 1961-1962, 1994, 1999 and 2007. It runs north-south from Pinar de Chamartin to Valdecarros passing through the city centre.
Line 2 opened in 1924 (Sol-Ventas) and it was extended in 1925, 1929, 1932, 1958, 1964 and 1970, 1998, 2007 and 2011. Line 2 currently runs from Cuatro Caminos to Las Rosas; an intermediate branch (the so-called Line R or "Ramal") from Opera to Principe Pio opened in 1925; it's operated as a shuttle service.
Line 3 opened in 1936 (Sol-Embajadores) and it was extended in 1941, 1949, 1963 and 2007; Line 3 currently runs from Moncloa to Villaverde Alto.
The first section of Line 4 (Goya-Argualles) opened in 1944; it was extended in 1958 (adsorbing the former Line 2 segment Goya-Diego de Leon), in 1973, 1979, 1998 and 2007. Line 4 currently runs from Arguelles to Pinar de Chamartin.
The first section of the current Line 5 opened in 1961 (Callao-Carabanchel) and it was extended in 1968, 1970, 1976, 1980, 1999, 2002 and 2006. Nowadays Line 5 runs from Casa de Campo to Alameda de Osuna.
Line 6 (Circular) opened in 1979 (Cuatro Caminos-Pacifico) and it was extended in 1981, 1983, 1987, 1995 (at that date Line 6 loop was completed) and 2007 (with an intermediate stop).
Line 7 opened in 1974 (Pueblo Nuevo-Las Musas) and it was extended in 1975, 1998 and 2007. Line 6 interchanges with all the other metro lines except Line 12.
Line 8 opened in 1998 (Mar de Cristal-Campo de Las Naciones) and it was extended in 1999 and 2002. It currently runs from Nuevos Ministerios to Aeropuerto T4 (at Barajas Airport).
Line 9 opened in 1980 and it was extended in 1983, 1986 and 1998. Line 9 currently consists in two sections: an urban segment from Paco de Lucia to Puerta de Arganda (that's the properly said Line 9) and a suburban segment (mostly ground level) from Puerta de Arganda to Arganda del Rey (referred as Line 9b).
Line 10 opened in 1961 adsorbing the former Line 8 (Fuencarral-Aluche) and being linked to the former Line 10 (Aluche-Alonzo Martinez); it was extended in 2007 (Fuencarral-Hospital del Norte/Hospital Infanta Sofia).
Line 11 opened in 1998 (Plaza Eliptica-Pan Bendito) and it was extended in 2006 (Pan Bendito-La Peseta).
Line 12 (MetroSur) opened in 2003; it's a long circular line which connects each other many southern suburbs of the metropolitan area. MetroSur interchanges with Line 10 at Puerta del Sur stop.
The properly said metro network was integrated in 2007 by 3 light metro lines (ML1, ML2, ML3), that connect some important suburban areas to the city centre; the choice of a light metro system with limited underground sections (instead of a full metro) was motivated by the consideration that the predicted ridership of these new lines could not justify the high costs of full metro lines. ML1 (northern side) goes from Pinar de Chamartin (where it interchanges with Line 1 and Line 4) to Las Tablas (where it interchanges with metro Line 10). ML2 and ML3 (western side) both starts at Colonia Jardin (where they interchange with metro Line 10) running north to Estacion de Aravaca (ML2) and west to Puerta de Boadilla (ML3).
