== History ==

=== Initial plans ===
[[File:Metro Lisboa timeline.gif|thumb|left|Evolution of the Lisbon Metro, 1959–2012]]
The idea of building a system of underground railways for the city of Lisbon first arose in 1888. It was first proposed by Henrique de Lima e Cunha, a military engineer who had published a proposal in the journal ''Obras Públicas e Minas'' ''(Public Works and Mines)'' for a network with several lines that could serve the Portuguese capital. Concrete plans took longer to evolve, though. Lanoel Aussenac d'Abel and Abel Coelho presented theirs in 1923, and José Manteca Roger and Juan Luque Argenti theirs one year later, in 1924. None of these plans were carried out.<ref name="history">{{cite web|url=http://www.metrolisboa.pt/empresa/um-pouco-de-historia/|title=Um pouco de história|website=metrolisboa.pt|language=pt|url-status=dead|archive-url=https://web.archive.org/web/20180205072309/http://www.metrolisboa.pt/empresa/um-pouco-de-historia/|archive-date=5 February 2018}}</ref>

After [[World War II]], in which Portugal remained neutral, the national economy took off and the financial possibilities arising from the [[Marshall Plan]] provided a strong boost to the potential construction of a metro in Lisbon. A society was formed on 26 January 1948 with the purpose of studying the technical and economic feasibility of the project.<ref name="history"/>

Construction began on 7 August 1955, and four years later, on 29 December 1959, the Lisbon Metro was inaugurated. The network was formed by a Y-shaped line linking Restauradores to Rotunda (now Marquês de Pombal), branching then to Entre Campos and to Sete Rios (now Jardim Zoológico), where the rolling stock depot (PMO I) which was also linked to the outer-loop [[Linha de Cintura|Cintura Line]] of [[Comboios de Portugal|CP]] was located. Two services were operated on the system: one between Restauradores and Sete Rios (which later became part of the Blue Line), and one between Restauradores and Entre Campos (which later became part of the Yellow Line).

The new system was well received by the public, and in the first year the Metro carried more than 15.3 million passengers. The metro has proved an important factor in urban development of the city, outlining new areas of housing and services. On 27 January 1963, the first phase of the central portion of the network (later the Green Line) opened with an extension from Restauradores to Rossio; the second phase (from Rossio to Anjos) opened on 28 September 1966 and the third phase (from Anjos to Alvalade) opened on 18 June 1972.

After this first extension, no further extensions began construction until the early 1980s. In 1974, after the [[Carnation Revolution]], the management model was changed, being nationalized in 1975 and renamed ''Metropolitano de Lisboa, EP'' in 1978. Under the new management, works were carried to enlarge platforms, originally designed to receive two cars, so that these could receive four cars.<ref name="history"/>

=== 1980–1989: Initial expansion ===

In the 1980s, additional extensions to the metro network began to be studied. An extension from Alvalade to Calvanas was planned to begin construction in 1980 and the extension from Sete Rios to Colégio Militar (later Colégio Militar/Luz) was expected to begin construction in 1982.

In 1984, works began to extend the eastern branch of the initial line from Entre Campos to Campo Grande (then called Cruz Norte). At the same time, construction of the extension from Alvalade to Campo Grande began; plans to build a station at Calvanas, near the Júlio de Matos hospital, had already been abandoned at the time.

By the end of the decade, on 14 October 1988, the extension connecting Sete Rios to Colégio Militar/Luz was inaugurated, opening three stations: Laranjeiras, with artwork by [[Sá Nogueira]], Alto dos Moinhos (artwork by [[Júlio Pomar]]), and Colégio Militar/Luz (artwork by [[Manuel Cargaleiro]]). Cidade Universitária (connected to the main [[campus]] of the [[University of Lisbon]], with artwork by [[Maria Helena Vieira da Silva]]) opened at the same time, as part of the extension from Entre Campos to Campo Grande. These four stations were the first to be built from scratch with platforms long enough to receive six cars ({{Convert|105|m|ftin}}) and with artwork in the platforms themselves.<ref name="history"/>

[[File:PicoasMetroLx2.JPG|right|thumb|Picoas station (Yellow Line).]]
[[File:RomaMetroLx4.JPG|right|thumb|Roma station (Green Line).]]
In 1990, the Network Expansion Plan was presented, which included extensions from Rossio to Cais do Sodré and from Restauradores to Baixa-Chiado, splitting the Y in Rotunda (extending the branch from Picoas to a new station, Rato) and the extension Colégio Militar/Luz–Pontinha (including a new depot near the Pontinha station, PMO III).

In 1991, the first prototype of the ML90 car series was presented, consisting of two triple units (motor-trailer-motor) of six cars (with the first unit being numbered M-201, R-202 and M-203), built by [[Sorefame]]/[[Bombardier Transportation|Bombardier]]. These cars had a digital destination sign, were generally more comfortable and could operate with or without the trailer. The motor cars in these two triple units were also the only ones to have a front door to the cab, which was not included in further batches.

On 3 April 1993, the elevated Campo Grande station opened, along with the expansions Alvalade–Campo Grande and Cidade Universitária–Campo Grande. With this extensions, the network grew {{convert|5.0|km|mi|abbr=on}}. In the same month, the ML90 prototype cars were used for the first time.

In 1993, the second Network Expansion Plan was presented, intended to serve [[Expo '98]]. It recommended that the Metro should operate the following routes by 1999:

* {{routeBox|A||#aa0000}} would run from the northwest end of the city at [[Pontinha (Odivelas)|Pontinha]] to the east end of Baixa (Terreiro do Paço);
* {{routeBox|B||#006600}} would run from the Lumiar to Campolide;
* {{routeBox|C||navy}} would run from [[Telheiras (Lisbon Metro)|Telheiras]] to the seaport at Cais do Sodré;
* {{routeBox|D||purple}} would run from Alameda to the exposition site at Moscavide in the northeastern end of the city.

The PMO II depot at [[Campo Grande]] was finished in the autumn of 1994 after eleven years of works. At the end of this year, the second batch of ML90 was ordered, consisting of 17 triple units (or 51 cars). On 15 July 1995, the two services were finally realigned into Line A (blue) between Colégio Militar/Luz and Campo Grande via Rossio, and Line B (yellow) between Campo Grande and Rotunda. The old Rotunda station (now Rotunda I) was extended from 75 to 105 metres and totally refurbished, while the new station (Rotunda II) already had a platform with 105 metres.

By the end of 1996, the second batch of ML 90 (numbered M-207 to M-257) was ready; colors and materials used in this second batch differed somewhat from that made up the first. The rolling stock was now composed of 191 coaches: 80 of them ML7, 54 ML90 and 57 ML79. On 18 October 1997, the Blue Line expansion from Colégio Militar/Luz to [[Pontinha (Odivelas)|Pontinha]] opened, expanding the network by {{convert|1.6|km|mi|abbr=on}}. In December of the same year, Rato opened, {{convert|0.6|km|mi|abbr=on}} from Rotunda II. Orders for new rolling stock continued in 1997, when half of the cars now known as ML95 were delivered (19 electric triple units, motor-trail-motor, or 57 cars). These new coaches, which look similar to ML90, have some technical differences, like a different engine and electrical door control (unlike the pneumatic control used on its predecessors). The new logo of the Lisbon Metro was first inserted into these new coaches.

1998 was a year when most of the said expansion projects were completed; as early as March the names of four stations had changed:

* Sete Rios → Jardim Zoológico
* Palhavã → Praça de Espanha
* Rotunda I and II → Marquês de Pombal I and II
* Socorro → Martim Moniz

In March 1998, the section between Rossio and Campo Grande became part of the Green Line, which removed the connection between Restauradores and Rossio stations from regular service. On 18 April, the section Rossio - Cais do Sodré ({{convert|1.4|km|mi|abbr=on}}) was opened, with two stations: Baixa-Chiado and Cais do Sodré, the latter connecting to the train and boat stations.

The Red Line (Line D at the time) would be inaugurated on 19 May 1998, three days before the opening of Expo '98. This line was {{convert|5|km|mi|abbr=on}} long and included five new stations: Alameda II, Olaias, Bela Vista, Chelas, and Oriente; the line began running six car trains beginning in June of that year on an experimental basis in order to satisfy the demand of passengers visiting Lisbon during Expo '98. By this time, the entire ML95 series had been delivered, numbered M-301 to M-414.

Later in 1998, Cabo Ruivo (on 18 July) and Olivais (on 8 August) opened as infill stations on the Red Line, between Chelas and Oriente. The rolling stock was then composed of 305 cars – 80 ML7, 54 ML79, 57 ML90 and 114 ML95, and the network comprised 40 stations.

In 1999, the PMO III depot opened near the Pontinha station, replacing the old PMO I depot at Sete Rios, in an event where the prototype of the future car series (now known as ML97) was presented, which would consist of 18 articulated triple units (54 cars). The main difference from the previous series was the possibility of free movement between each car. In addition, the prototype had a more modern image, and also introduced digital automatic passenger information. According to the operator, the trailer of these triple units can be removed, although this has never been witnessed. The first cars were issued during 1999, numbered M-501 to M-554. The rolling stock, at the turn of the millennium, was made of 361 cars of five train types (80 ML7, 54 ML79, 57 ML90, 114 ML95, 54 ML97), the largest number of train cars to date before the retirement of the ML7 and ML79 series in 2000 and 2002, respectively.

On 2 November 2002, under [[Manuel Frasquilho]]'s tenure as president, the Green Line's extension from Campo Grande to [[Telheiras (Lisbon Metro)|Telheiras]] opened. In 2004, the network opened its first extensions outside the geographical limits of the city: first, in March, with the expansion of the Yellow Line from Campo Grande to Odivelas (which included five new stations, two of which are aboveground); then, in May, the Blue Line was extended from [[Pontinha (Odivelas)|Pontinha]] to Amadora Este. Later that year, construction of the Red Line segment between Alameda and São Sebastião began.

On 19 December 2007, after 11 years of construction, the final {{convert|2.2|km|mi|abbr=on}}-long section of the Blue Line between Baixa-Chiado and Santa Apolónia opened, with some controversy and many successive delays due to the difficulty of construction. The segment was originally slated to open in 2001, but in 2000, cracks were discovered in the original tunnel that led to land subsidence. The consequent flooding of the tunnel seriously slowed down the completion of work and road traffic at the [[Praça do Comércio]] and part of the Avenida Infante D. Henrique was forced to be closed temporarily while the new tunnel was constructed in its place. The stations themselves (Terreiro do Paço and Santa Apolónia) were completed in the summer of 2007.

On 29 August 2009, the Red Line section between Alameda II and São Sebastião II was inaugurated, such that all lines now cross each other.

On 17 July 2012, the Red Line was extended between Oriente and [[Aeroporto (Lisbon Metro)|Aeroporto]], adding {{convert|3.3|km|mi|abbr=on}} to the network. Three new stations have been inaugurated: Moscavide, Encarnação and [[Aeroporto (Lisbon Metro)|Aeroporto]], which is directly linked to the [[Lisbon Portela Airport]]. A journey from the central Saldanha station to the Lisbon Airport now only lasts about 16 minutes. The Red Line also serves the Moscavide neighbourhood, and was expected to carry 400,000 extra passengers each year.<ref name="metrolisboa.pt">{{cite web|url=http://www.metrolisboa.pt/2012/07/prolongamento-da-linha-vermelha-ao-aeroporto/|title=Prolongamento ao Aeroporto {{!}} Abertura ao Público|website=metrolisboa.pt|language=pt|date=16 July 2012|url-status=dead|archive-url=https://web.archive.org/web/20120717041308/http://www.metrolisboa.pt/2012/07/prolongamento-da-linha-vermelha-ao-aeroporto/|archive-date=17 July 2012}}</ref>

The Blue Line segment between Amadora Este and Reboleira on the Blue Line opened on 17 April 2016, twelve years after the initial portion of the segment between Pontinha and Amadora Este was completed.<ref>{{cite web|url=http://www.noticiasaominuto.com/pais/569696/ligacao-do-metro-de-lisboa-a-linha-de-sintra-e-inaugurada-na-quarta|title=Ligação do metro de Lisboa à Linha de Sintra é inaugurada na quarta|work= Notícias ao Minuto |date=11 April 2016|language=pt}}</ref>

===2017–present===
Further modernization works to the Lisbon Metro began on 19 July 2017, when the Arroios station on the Green Line was closed for extensive renovations and the expansion of the platforms to allow six-car trains; the station was originally scheduled to reopen in 2019, but reopening was later postponed to no earlier than 2021 due to construction delays. The renovated station finally reopened in September 2021. On 8 June 2018, portions of the platform edges at the Encarnação station on the Red Line partially collapsed onto the tracks, which necessitated a week-long closure of the segment between the Moscavide and Aeroporto stations.<ref>{{Cite web|last=Neves|first=Sofia|title=Lisboa.

On 29 September 2020, portions of the tunnel near the Praça de Espanha station on the Blue Line collapsed while the station was undergoing renovation works, necessitating a temporary closure of the line between Laranjeiras and Marquês de Pombal stations.<ref>{{Cite web|url=https://24.sapo.pt/atualidade/artigos/desabamento-leva-a-interrupcao-da-linha-azul-no-metro-de-lisboa |title=Metro de Lisboa: Desabamento leva a interrupção da linha azul, e faz quatro feridos.

====Proposed extensions====
[[File:Metro_Lisboa_Plano_2022.png|left|thumb|Proposed map of the network.]]
On 8 May 2017, the government of Portugal announced an extension of the Yellow Line to Cais do Sodré as part of a [http://www.portugal.gov.pt/pt/ministerios/mamb/docs/20170508-mamb-plano-metro.aspx new operational master plan]. The extension, which will connect the Yellow Line with the Green Line and is expected to open in 2024, will contain two new stations at [[Estrela (Lisbon Metro)|Estrela]] and [[Santos (Lisbon Metro)|Santos]]; Campo Grande will also be reconstructed as part of the project.

An extension to the Red Line is also projected to be built, extending it to four entirely new stations: Campolide/Amoreiras, Campo de Ourique, Infante Santo and Alcântara. The project, if it goes forward, is projected to be completed by around 2026.<ref name="projetos.metrolisboa.pt">{{cite web|url=https://projetos.metrolisboa.pt/expansao/projetos-em-estudo/|title=Projetos em Estudo - Metro de Lisboa|language=pt|access-date=10 October 2022}}</ref>

A new line, the Violet Line, is also projected to be constructed in the coming years. Unlike the rest of the Metro, this line would not be heavy rail, nor mostly underground, but rather [[light rail|surface light rail]]. It will connect the area of Infantado, in [[Loures]] to the metro station of [[Odivelas (Lisbon Metro)|Odivelas]] and then to Beatriz Ângelo Hospital, with the line making a "C" shape. It is planned to be completed by around 2025.<ref name="projetos.metrolisboa.pt"/>

== Operation ==

===Operating hours and frequency===
Metro service starts every day at 06:30 and stops at 01:00 (the last trains arrive at the terminal stations by 01:30). However, some station exits close before 01:00. Trains run at a 5–8 minutes [[headway]].

===Ticketing and fares===
[[File:Lisbon metro viva viagem.jpg|thumb|Viva Viagem cards (2014)]]
There are two methods of payment: 
*The contactless Cartão 7 Colinas/Viva Viagem card
*The contactless Lisboa Viva card which can also double up as monthly passes
*The contactless Lisboa Navegante card which can either be charged with the metropolitan pass, or only for the Lisbon municipality

All three cards can also be used on other modes of transport like [[Fertagus]], [[Comboios de Portugal|CP]] (including [[CP Urban Services|its suburban rail service]]) and the [[Transtejo & Soflusa]] ferry service.

== Rolling stock ==

===Current===
Currently, four types of trains are in service on the Lisbon Metro. Unlike most metro systems, the trains do not have any form of [[air conditioning]] due to the small size of the tunnels. 
* ML90 series (since 29 March 1993)
* ML95 series (since 1997)
* ML97 series (since 1 February 1999)
* ML99 series (since 3 July 2000, 1 carriage destroyed in a PMO incident in 2002)

===Former===
* ML7 series (from 29 December 1959 until 31 January 2000, two cars preserved and run on certain special occasions)
* ML79 series (from 1 January 1984 until 11 July 2002, two cars preserved for exhibition)

===Future===
* ML20 series (from January 2025)
* ML24 series (from 2027)

In 2021, [[Stadler Rail]] and [[Siemens Mobility]] won a contract to supply 14 three-car trains for Lisbon Metro.<ref>{{Cite web |title=Stadler and Siemens Mobility consortium wins contract to modernize and upgrade the Lisbon Metro |url=https://stadlerrail.com/media/pdf/2021_0507_media%20release_metro%20lisbon_en.pdf |date=10 May 2021}}</ref> They are designated as the ML20 series. The first train was delivered from the [[Stadler Rail Valencia SAU]] factory in Spain on 9 August 2024 and is planned to enter service in January 2025.<ref>{{cite web | url=https://www.metrolisboa.pt/institucional/2024/08/09/metropolitano-de-lisboa-recebe-as-primeiras-novas-carruagens/ | title=Metropolitano de Lisboa recebe as primeiras novas carruagens | date=9 August 2024}}</ref> 

In October 2024, Lisbon Metro again signed a contract with Stadler, this time for the supply of 24 three-car trains with an option for 12 more, designated as the ML24 series.<ref>{{cite web | url=https://www.metrolisboa.pt/institucional/2024/10/30/apresentacao-das-novas-unidades-triplas-ml-24-no-ambito-do-contrato-assinado-para-a-aquisicao-de-24-unidades-triplas/ | title=Metropolitano de Lisboa apresenta as novas carruagens da série ML 24 no âmbito do contrato assinado para a aquisição de 72 novas carruagens | date=30 October 2024}}</ref>

== Art ==
The architecture and decor of an underground station is a key element for the well-being of passengers, and art works to make travel more appealing. Lisbon Metro is one of the various underground systems in the world where art is best represented, much like the [[Munich U-Bahn]] in Germany, [[Moscow Metro]] in Russia, [[Montreal Metro]] in Canada and the [[Stockholm metro]] in Sweden. From the beginning, there was a concern to make a smooth visual transition between surface and underground. Architect [[Francisco Keil do Amaral]] (1910–1975) designed a station model, which was used as a template for all stations built until 1972. In this model, the decor was very moderate, with smooth but firm lines, much like the [[Estado Novo (Portugal)|Portuguese political regime]] at the time. The original eleven stations, except Avenida, had artwork by his wife, painter [[Maria Keil]] (1914–2012).

In 1988, with the completion of new expansions, there was still a concern about organizing and decorating stations, thus these stations featured works by contemporary Portuguese artists: Rolando de Sá Nogueira in Laranjeiras, Júlio Pomar in Alto dos Moinhos, Manuel Cargaleiro in Colégio Militar/Luz, and Vieira da Silva in Cidade Universitária.

Since then, art has become the norm in the Lisbon Metro; lighting plays with the brightness of the [[azulejo]] tiles that are present in almost every station. In recent years, the oldest stations have been refurbished, not only to enhance the decor and aesthetics, but also to improve accessibility for passengers with reduced mobility. Parque station is generally considered to be the most valuable and interesting of them all, where the tiles map details of the Portuguese [[Portuguese maritime exploration|voyages of discovery]] and their philosophical and literary links.
