The '''Athens Metro''' ({{langx|el|Μετρό Αθήνας|Metro Athinas|translit-std=iso}}) is a [[rapid transit]] system serving the [[Athens]] urban area in Greece. [[Line 1 (Athens Metro)|Line 1]] opened as a single-track conventional steam railway in 1869 and was electrified in 1904. Beginning in 1991, [[Elliniko Metro]] S.A. constructed and extended [[Line 2 (Athens Metro)|Lines 2]] and [[Line 3 (Athens Metro)|3]].<ref name="90s-construction"/>
It has significantly changed Athens by providing a much-needed solution to the city's traffic and [[air pollution]] problem, as well as revitalising many of the areas it serves.
Extensions of existing lines are under development or tender, like the Line 2 extension to Ilion where tender started in 2023, as well as a new [[Athens Metro Line 4|Line 4]], whose central section began construction in October 2021.<ref>{{Cite web |date=3 May 2023 |title=Υποβολή φακέλων εκδήλωσης ενδιαφέροντος στο διαγωνισμό για την επέκταση του Μετρό προς Ίλιον |url=https://www.athenstransport.com/2023/05/ilion-metro-ekdilosi-endiaferontos/ |access-date=19 August 2023 |website=Athens Transport |language=el}}</ref>
The Athens Metro is actively connected with the other means of public transport, such as buses, trolleys, the [[Athens Tram]] and the [[Athens Suburban Railway]]. The Athens Metro is hailed for its modernity (mainly the newer lines 2, 3), and many of its stations feature works of art, exhibitions and displays of the archaeological remains found during its construction. Photography and video-taking is permitted across the whole network<ref>{{Cite web|url=http://www.synigoros.gr/resources/docs/199930.pdf |title=synigoros.gr |url-status=dead |archive-url=https://web.archive.org/web/20160314231156/http://www.synigoros.gr/resources/docs/199930.pdf |archive-date=14 March 2016 }}</ref> and [[street photography|street photographers]] often work in Athens Metro. This was the only metro system in [[Greece]], before the [[Thessaloniki Metro]] began operations on 30 November 2024.

==History==

{{Expand language|date=October 2022|langcode=el|section=1|topic=transp}}

===Piraeus–Kifissia Railway (Line 1)===
Until 28 January 2000, Line 1 was the only rapid-transit line in Athens. The Athens and Piraeus Railway Company (SAP) opened a [[Steam railway|steam]] [[Single-track railway|single-track]] mixed cargo and passenger railway line on 27 February 1869 and was run between {{stl|Athens Metro|Piraeus}} and {{stl|Athens Metro|Thiseio}}. It was electrified in 1904. On 4 February 1885 [[Lavrion Square-Strofyli railway|Lavrion Square-Strofyli]] [[Steam railway|steam]] [[Narrow-gauge railway|narrow gauge]] [[Single-track railway|single-track]] mixed cargo and passenger railway line opened and was run at the time from Attiki Square to Kifissia through Iraklio. These originally mixed cargo and passenger railway lines gradually merged and converted to a rapid-transit system. The section between Kifissia and Strofyli was abandoned.

From 1869 to 1926 the line was operated by SAP. From 1926 to 1976 the line was operated by [[Hellenic Electric Railways]] (EIS). In 1976 the EIS was nationalized and renamed Athens-Piraeus Electric Railway Company (ISAP), which continued to operate what became line 1 of the Athens Metro until 16 June 2011.<ref name="about-stasy"/>

Since the current Line 1 opened, the government has proposed many expansions to the subway network, including a 1963 plan for a fourteen-line subway network.<ref>{{cite web|url=http://www.tovima.gr/society/article/?aid=527217|script-title=el:Οραμα για 14 γραμμές Μετρό στην Αττική από το 2000|last=Hekimoglou|first=Achilleas|date=24 August 2013|publisher=Το Βήμα ([[To Vima]])|language=el|access-date=23 February 2024}}</ref> Construction of Lines 2 and 3 began in November 1992 to decrease traffic congestion and improve Athens' air quality by reducing its smog level.<ref name="90s-construction">{{cite web|url=http://www.ametro.gr/page/default.asp?la=2&id=376|title=AttikoMetro Inside – Base Project|date=9 September 2012|publisher=Attiko Metro S.A.|access-date=3 October 2012}}</ref> Both lines were constructed underground. Lines 2 and 3, built by Attiko Metro S.A. and operated until 2011 by Attiko Metro Operations Company, are known respectively as the red and blue lines and were inaugurated in January 2000. Line 3 was extended to the [[Eleftherios Venizelos International Airport]] in summer 2004, and Line 2 was extended to [[Anthoupoli metro station|Anthoupoli]] and Elliniko in 2013.

===Lines and stations===

{{Main|List of Athens Metro stations}}

The Athens Metro consists of three lines totalling {{convert|91.7|km|mi|abbr=off}} and 66 stations: Line 1 (Green) is {{convert|25.7|km|mi|abbr=off}} long with 24 stations, Line 2 (Red) is {{convert|18.7|km|mi|abbr=off}} long with 20 stations, and Line 3 (Blue) is {{convert|47.3|km|mi}} long with 24 stations.<ref name="metro-stats-2022"/> [[STASY]] owns and operates 62 of the 66 stations: three other stations ({{stn|Pallini}}, {{stn|Paiania–Kantza}} and {{stn|Koropi}}) belong to GAIAOSE and the {{stn|Athens Airport}} station belongs to the [[Athens International Airport S.A.|operator]] of the [[Athens International Airport]].

The system has five interchanges, at {{metro|Attiki}}, {{metro|Monastiraki}}, {{metro|Omonia}}, {{metro|Piraeus}} and {{metro|Syntagma}}, allowing all three to interchange with each other at least once. Each line also has at least one connection with the [[Athens Suburban Railway]], and the [[Athens Tram]].

Line 2 is entirely underground. Line 1 is mostly overground, with an underground section spanning between the Monastiraki and Attiki stations, and an additional underground station (Kato Patisia) in central Athens. Line 3 is mostly underground; Trains that run an overground route are only those with the airport as final destination. The overground section of Line 3, east of the tunnel portal near {{stl|Athens Metro|Doukissis Plakentias}}, is open. In the tunnel sections up and down lines share a common tunnel, except for approaches to stations with an island platform (such as Egaleo). [[Rail yard|Train maintenance facilities]] are located at Attiki, Faliro, Irini, Piraeus, Kifissia and Thissio for Line 1, and Doukissis Plakentias, Eleonas and Sepolia for Lines 2 and 3.

The Athens Metro's three lines carried approximately 1,353,000 passengers daily in 2010.<ref name="Lines2&3" />

== Rolling stock ==
{{Main|Athens Metro rolling stock}}
The network uses [[standard gauge]] electric trains which in most places run on [[750 VDC|750&nbsp;]] [[Volt|V]] [[Direct current|DC]] [[third rail]], but the section of Line 3 running to the airport requires trains which can use [[overhead line]]s of [[25 kV AC railway electrification|25&nbsp;kV]] [[Alternating current|AC]], 50&nbsp;Hz.

The Athens Metro classifies rolling stock by "batch" for Line 1 and "generation" for Lines 2 and 3 because ISAP and [[Attiko Metro Operation Company|AMEL]] used different classification systems for rolling stock before consolidation. Six types of rolling stock operate on the network, all equipped with third rail current collection systems; however, only seven second-generation trains have the necessary overhead line equipment to serve Line 3 from {{stl|Athens Metro|Doukissis Plakentias}} to {{stl|Athens Metro|Airport}}.

The eighth batch (introduced in 1983) is the oldest rolling stock in passenger service, while the third generation (introduced in 2013) is the latest rolling stock in passenger service. The eighth- and tenth-batch stock is externally similar, but the former has [[Split-flap display|split-flap headsigns]] in [[Johnston typeface]] and a cream-and-green interior colour scheme. An extensive refurbishment programme is in progress for the 8th batch (as of 2023), and to cover for trains undergoing refurbishment, up to five 1st generation Line 2/3 trains have been borrowed to operate on Line 1.
Line 1 halfsets have driving cabs at both ends, unlike the Line 2/3 halfsets which have a driving cab at the outer ends, but only basic driving apparatus for shunting purposes only at the inner ends; thus, they can only operate on their own inside depots.[[File:Athens metro Victoria station.jpg|thumb|The west entrance to Athens Metro line 1 Victoria station.]]

===Signalling===
{{Main|Greek railway signalling#Athens Metro signalling|l1=Greek railway signalling → Athens Metro signalling}}
Line 1 uses two-aspect red/green home signals, yellow/green distant signals and a passenger information system (PIS). The current system replaced 1950s-era semaphore signals. The automatic train protection (ATP) system of Line 1 was fully installed in 2023 which replaced the previous Indusi system.<ref>{{Cite web |date=20 March 2023 |title=Ενεργοποιήθηκε το Σύστημα Ασφάλειας Κυκλοφορίας Συρμών στη γραμμή του ΗΣΑΠ |url=https://www.athenstransport.com/2023/03/atp-grammi-isap/ |access-date=18 August 2023 |website=Athens Transport |language=el}}</ref>

Lines 2 and 3 use the Alstom automatic train supervision system (ATS) and a passenger information system (PIS). Two-aspect red/white colour signals are used at points and junctions only.

==Fares==
Fares are prepaid, either as short term tickets valid for 90 minutes, 24 hours, three days, five days, or as long term tickets. As of September 2020, there are two types of fare products, the ATH.ENA Ticket and ATH.ENA Card, both of which are validated using a contactless system (by scanning the ticket or card at the electronic validating machines). The tickets are valid on all modes of public transport in Athens except on trains and buses to the airport.<ref name="Ticket Types&Prices">{{cite web |url=http://oasa.gr/pdf/tickets.pdf |title=Tickets |website=OASA S.A |access-date=22 September 2015}}</ref> Passengers cannot buy a fare on board the bus. To travel to or from the airport, passengers may buy a one-way ticket for €9 or a 3-day ticket for €20 which also includes unlimited local trips and a return trip to the airport.  Arrival at the airport without having paid the appropriate fare will incur a €72 fine, reduced to €36 if paid within 10 days. Term tickets are available in 30, 90, 180, and 365 day periods and are available only with a personalized ATH.ENA Card. Reduced fares are available for university students, seniors, disabled and persons under 18. During a fare control the passengers that are entitled to a reduced fare have to show ID card, student card or passport.<ref name="Cards Types&Prices">{{cite web |url=http://stasy.gr/index.php?id=464&L=0 |title=Travel Cards |language=Greek |website=STASY S.A./OASA S.A. |access-date=23 September 2015}}</ref> Children under the age of 6 are entitled to travel for free with all means of transportation. On buses and [[Athens Tram|trams]] the ticket or card must be validated only when entering the vehicle/car by scanning the ticket at the electronic validating machines.

== Archaeological excavations and exhibits ==
{{see also|Syntagma Metro Station Archaeological Collection}}
During construction of the metro tunnels, artifacts of archaeological interest were discovered and [[rescue archaeology]] was employed. Teams of archaeologists worked ahead of, then with, engineers for six years, protecting and recording archaeological finds (streets, houses, cemeteries, sanctuaries, public workshops, foundry pits, kilns, aqueducts, wells, cisterns, drains and sewage tunnels). This afforded new insight into the city's ancient topography, through unprecedented infrastructure development combined with the study and preservation of archaeological data. Exhibitions of ancient artifacts or replicas are found at a number of metro stations, including [[Monastiraki metro station|Monastiraki]], [[Akropoli metro station|Akropoli]] and [[Syntagma metro station|Syntagma]].[[File:DSC 3160 syntagma metro station july 2018.jpg|alt=Open indoor area with ticket windows, fare-collection machines and an escalator|thumb|300x300px|Concourse level of Syntagma Metro station (2018).]]

<nowiki>**</nowiki>The Development Plan refers it as Line 4 branch but there are unofficial plans that this branch is part of the future Line 5.

If and when these projects are completed, the Athens Metro is expected to reach {{convert|141.7|km|mi|1|sortable=on|abbr=on}} in length and serve a total of 110 stations by 2040.

==={{anchor|Planned Line 4}}Line 4===
{{Main|Line 4 (Athens Metro)}}
A fourth line is planned for the Athens Metro and it has been incorporated in the roadmap for the development and expansion of [[public transport in Athens]] since 2005. The new line in its totality will extend over a length of {{convert|38.2|km|mi|abbr=on}}, adding thirty five (35) new stations to the Athens Metro system. The cost of the entire project is estimated at 3.3 billion [[Euro|EUR]].<ref>{{cite web|url=https://www.ametro.gr/?page_id=8633&lang=en |title=Attiko Metro Γραμμή 4 (Line 4) |publisher=Attiko Metro S.A. |access-date=17 March 2020}}</ref> The recommendation is for lighter rolling stock than the type used in existing lines of Athens Metro which would operate [[Automatic train operation|automatically without a driver]]. In November 2020, [[Alstom]] was chosen to supply the line with 20 4-car automated [[Alstom Metropolis|Metropolis]] trains, operated under Urbalis 400 signalling system.<ref>{{cite web|url=https://www.alstom.com/press-releases-news/2020/11/alstom-consortium-selected-first-section-athens-metro-line-4|title=Alstom consortium selected for first section of Athens Metro Line 4|publisher=Alstom |access-date=5 November 2020}}</ref>

The first phase of Line 4 will be between ''Alsos Veikou'' and ''Goudi'' stations, predicting fifteen (15) new stations and a length of {{convert|12.8|km|mi|abbr=on}} of new track. An [[call for bids|invitation to tender]] for the construction of the first phase of Line 4 was issued in September 2018. The construction started in mid to late-2021 and is scheduled to be completed in 2029 or 2030. The estimated cost for constructing the first phase of the new line is 1.51 billion EUR. Currently, the project of the first phase is considered to follow a [[Public-private partnership|PPP]] scheme which might be extended for constructing the whole new line. An alternative solution is a mixed funding between the [[European Investment Bank|EIB]] and the Greek State. It is also a high-profile candidate project to be included in the [[European Commission Investment Plan for Europe|Juncker Plan]] of EU that will include also the second phase of Line 4 of Athens Metro.

The [[European Investment Bank]] is allocating a €730 million loan over 30 years to finance the building of the first segment of the Line 4 metro, which will connect Alsos Veikou and Goudi. The initiative will also assist Athens by reducing the number of private automobiles on the road by 53 000, resulting in 318 tonnes fewer [[Greenhouse gas emissions|CO2]] released daily.<ref>{{Cite journal |last=Bank |first=European Investment |date=17 May 2023 |title=Cohesion and regional development Overview 2023 |journal=European Investment Bank |url=https://www.eib.org/en/publications/20230145-cohesion-and-regional-development-overview-2023 |language=EN}}</ref><ref>{{Cite web |last=pamela |date=10 February 2022 |title=Financing agreement for Alsos Veikou – Goudi metro section |url=https://www.railwaypro.com/wp/eur-580-million-financing-for-athens-line-4/ |access-date=15 June 2023 |website=Railway PRO |language=en-US}}</ref><ref>{{Cite web |last=Rani |first=Archana |date=8 February 2022 |title=Attiko receives $663m EIB loan for new Athens Metro line |url=https://www.railway-technology.com/news/attiko-eib-metro-line/ |access-date=15 June 2023 |website=Railway Technology |language=en-US}}</ref><ref>{{Cite journal |last=Bank |first=European Investment |date=11 September 2023 |title=Sustainable transport overview 2023 |url=https://www.eib.org/en/publications/20230266-sustainable-transport-overview-2023 |language=EN}}</ref>
