Line 5 of the Madrid Metro originally opened between Callao and Carabanchel on 5 June 1968, the latter sharing station platforms with then called Line S (for Suburbano) On 2 March 1970, the line was extended from Callao to Ciudad Lineal, however the section between Ventas and Ciudad Lineal was opened as part of line 2 in 1964. In 1976, section of Line S Carabanchel - Aluche was transferred to the line in order to provide easier transfer to downtown to new railroad line to Alcorcón and Móstoles, now part of Cercanías C-5 line. On 28 May 1980 the line was extended from Ciudad Lineal to Canillejas. On the 27 October 1999, Eugenia de Montijo station was added between Aluche and Carabanchel. The station is on the tunnel mouth of the line and is therefore overground. The mostly overground section between Aluche and Casa de Campo was handed over to Line 5 after Line 10 was extended south from Casa de Campo on 22 May 2002. On 24 November 2006, a two stop extension from Canillejas to Alameda de Osuna was opened. A unique feature of Line 5 is that it carries the only above ground island platform at Aluche, and it is the only station were the metro is above the Cercanías, which is normally the other way round. In the future, Line 5 is projected to be extended one stop north from Alameda de Osuna to Corralejos, where it will meet Line 8, however a new station will have to be built here to connect with line 5. Line 5 uses 6-car trains of classes 2000A and 2000B. It was the last line built in a narrow profile and gauge.
