Madrid
Madrid Metro system is one of the largest worlwide, with a remarkable growth in the last years. The first line opened in 1924 (currently line 1 connects Pinar de Chamartin to Valdecarros), followed by line 2 in 1924 (currently L2 runs from Cuatro Caminos to La Elipa; Ventas-La Elipa opened in 2007), by the so-called "Ramal" in 1925 (it's currently a L2 branch connecting Opera to Principe Pio with a shutlle service) and by line 3 in 1936 (L3 currently runs from Moncloa to Villaverde Alto, thank to Legazpi-Villaverde extension opened in 2007). All those old lines were used as air raid shelters during the civil war.
In 1944 the first stretch of line 4 (Diego de Leon-Argualles) was completed, adsorbing a former L2 section (Goya-Diego de Leon); currently L4 goes from Arguelles to Pinar de Chamartin (it was extended in 2007 as well). In 1961 it was the time of line 5, with its first segment Plaza de Espana - Carabanchel; nowaday L5 runs from Casa de Campo to Alameda de Osuna (it reached this terminal after an extension in 2006). Years '70s brought line 7 (opened in 1974) connecting Pitis to Henares, and line 6 (opened in 1979 and definitely closed into a circle after Arganzuela-Planetario extension in 2007) connecting all the lines with the exception of line 12. In 1980 line 9 was ultimated; this line is divided in 2 sections (Herrera Oria-Puerta de Arganda and Puerta de Arganda-Arganda del Rey, with an interchange stop at Puerta de Arganda). Line 10 opened in 1981, re-using and adsorbing a former suburban railway (years '60s); currently L10 connects Hospital del Norte to Puerta del Sur.
In the early years '90s Metro de Madrid public company begin to operate the whole system, which have had a huge expansion till the present time; line 8 (connecting Barajas Airport to the city center at Nuevos Ministerios) and line 11 (from Plaza Elaptica to Pan Bendito; this first section has been extended from Pan Bendito to La Peseta in 2006 and from La Peseta to La Fortuna in 2010) both opened in 1998. In 2003 it was the time of MetroSur (line 12), a long circular line (as L6) which connects many southern suburbs of the metropolitan area; it joins L10 at Puerta del Sur stop.
The properly said metro network was integrated in 2007 by 3 LRT lines (pre-metro: ML1, ML2, ML3), that connect some important suburban areas to the city center; the choice for an LRT system with limited underground sections was motivated by the consideration that the predicted ridership could not justify the high costs of real metro lines. ML1 (northern side) goes from Pinar de Chamartin (where it interchanges with line 1 and line 4) to Las Tablas (this stop will be served also by line 10 in the next future). ML2 and ML3 (western side) both starts at Colonia Jardin (metro line 10 stop) going west to Estacion de Aravaca (ML2) and Puerta de Boadilla (ML3).
