The [[Athens–Piraeus Electric Railways#Athens and Piraeus Railway Company|Athens and Piraeus Railway Company]] (SAP S.A.) first opened the line, between {{stl|Athens Metro|Piraeus}} and {{stl|Athens Metro|Thiseio}}, on 27 February 1869. On 4 February 1885 [[Lavrion Square–Strofyli railway]] line opened between [[Attiki metro station|Attiki Square]] and {{metro|Kifissia}}. These railway lines gradually merged and converted to a rapid-transit system. Line 1 was merged into the Athens Metro network upon the opening of lines [[Line 2 (Athens Metro)|2]] and [[Line 3 (Athens Metro)|3]] on 28 January 2000, although it remained operationally separate until 2011.

== History == The first steam-powered railway in Greece was inaugurated on 27 February 1869 and connected [[Thiseio|Thisio]] with [[Piraeus]] with a [[single-track railway]].<ref name="AM_history">{{Cite web |title=ΕΛΛΗΝΙΚΟ ΜΕΤΡΟ Α.Ε. |url=https://www.emetro.gr/page/default.asp/?la=1&id=22 |access-date=2025-02-02 |language=el}}</ref> It was electrified in 1904 and since then, taking into account international standards, it can be considered the first [[rapid transit|metro]] line in Greece.<ref name="UITP">{{Cite web |date=2013-03-13 |title=UITP - International Association of Public Transport |url=http://www.uitp.org/Public-Transport/metro/index.cfm |access-date=2024-12-01 |archive-url=https://web.archive.org/web/20130313221309/http://www.uitp.org/Public-Transport/metro/index.cfm |archive-date=13 March 2013 }}</ref><ref name="AM_history" /> Over the years, due to electrification, this first railway became known to the general public as the 'Electric Railway' or simply 'The Electric' (Ηλεκτρικός). Gradually, but mainly after the Second World War, it expanded to the north, until it reached [[Kifissia metro station|Kifissia]] in 1957.<ref name="STASY_line13">{{Cite web |date=2022-02-17 |title=ΣΤΑΣΥ {{!}} Σταθερές Συγκοινωνίες Μον.

With the creation of two new, underground metro lines in 2000 ([[Line 2 (Athens Metro)|Line 2]] and [[Line 3 (Athens Metro)|Line 3]]), it was renamed Line 1 of the Athens metro network, as it received the name "Line 1" as the oldest of the network.

In 1855, Prime Minister [[Alexandros Mavrokordatos]] tabled a Bill "on the establishment of a railway from Athens to Piraeus", which was published as Law TZ' in the Government Newspaper on 28 December. According to the law, the railway was classified as a project of public necessity, in order for the contractor to carry out the necessary land sales. Also, the right of exploitation was granted to the company or individual who would undertake the project for 55 years. Two years later, said right was increased to 75 years. Attempts to commission the project immediately began, but were unsuccessful. Twelve years later, in 1867, the project was finally awarded to English businessman Edward Pickering. The overland railway begins construction in November of the same year. The following year, in 1868, Pickering commissioned the continuation of the project to the newly founded company "Railways of Athens-Piraeus" (SAP SA).

=== The Thiseio–Piraeus line and the first expansion === The opening of the railway was scheduled for 15 February 1869, but was postponed to the 27th of the same month. It was finally ready on 17 February, when the SAP started running test trains.<ref name="STASY_line13"/>

On 27 February 1869, the Thiseio–Piraeus line was officially inaugurated, with [[Olga Constantinovna of Russia|Queen Olga]], Prime Minister [[Thrasyvoulos Zaimis]], ministers, soldiers, diplomats, other officials and journalists as passengers on the first route. The first six-car locomotive covered the 8.5 km route from [[Thisio]] to [[Piraeus]] in about 19 minutes.{{Vague|date=February 2025}}<ref name="AM_history"/>

A few days after the inauguration, on 3 March, the [["Aion" newspaper]] wrote: "The railway has been working regularly since last Friday. The flow of passengers has reached its maximum. Everyone is talking about the great benefits, let the completion of this work be accomplished. We also hope that this small line will be the beginning of a nationwide railway [[archipelago]]"

As the traffic of the line increased, simple stops began to become stations with platforms. In 1882 the stations of [[Faliro metro station|Faliro]] and [[Moschato metro station|Moschato]] were inaugurated. Originally the track was single, but by 1904, when it was electrified, it had been converted into a [[Double-track railway|double track]], as is the case to this day.

In order to implement the first extension of this urban means of transport, the Athens to Piraeus Railway Extension Company was founded by [[Stefanos Psychas]] and began the construction of a tunnel in 1889 from [[Thiseio metro station|Thisio]] to [[Omonia metro station|Omonia]]. The first station of Omonia, which was only partially underground (and partially open [[trench]]), was built at the intersection of Lykourgos and Athena streets and was inaugurated on 17 May 1895, together with the [[Monastiraki metro station|Monastiraki]] intermediate station, with a similar structure.<ref>{{Cite book |title=Οι Ελληνικοί Σιδηρόδρομοι - Η διαδρομή τους από το 1869 έως σήμερα |publisher=Μίλητος |year= |isbn= |location=Αθήνα |pages=25}}</ref>

=== Line "Lavriou Square-Strofyli" === In 1882, the [[Attica Railways|Railways of Attica]] (SA) were established to create and operate a single line that would connect Athens with [[Lavrio]]. An extension from [[Irakleio, Attica|Iraklio]] to [[Kifissia]] was added to the original engraving, while it was later extended north to Strofyli. The line was inaugurated in 1885. It was single, [[Metre gauge|metric gauge]] and operated with a [[steam engine]], the so-called ''Thirio(Beast)''. Its starting point was initially in Attica Square, which was named so because that was the starting point of the Attica Railways, while in 1889 the line was extended to the current Lavrio Square, which also took its name from the departure point of the trains to [[Lavrio]].<ref name=":02">{{Cite book |title=Οι Ελληνικοί Σιδηρόδρομοι - Η διαδρομή τους από το 1869 έως σήμερα |publisher=Μίλητος |year= |isbn= |location=Αθήνα |pages=38–44}}</ref>

=== The ''Elektrikos'' (Electric line) === The electrification of the Piraeus–Omonia line was inaugurated on 16 September 1904.<ref name="STASY_line13"/> But both the electrification and the [[tunnel]] in Omonia, examples of new technologies, were treated with reservation or even fear by many passengers.

In 1926, three fixed-track companies, SAP, Attica Railways and Athens-Piraeus Railways, which operated the [[trams]], cooperated with the English Power group.

Two companies emerged from this collaboration: the [[Electric Transport Company]] (HEM), which took over the operation of the Trams and the Kifissia Line, and the [[Hellenic Electric Railways]] (EIS). EIS replaced SAP and at the same time committed to improve the existing line and extend the underground tunnel to [[Attiki station]] with a [[double track]] to join Elektrikos with Kifissia, with a new, underground station below Omonia. In order to facilitate the works, the section of the Lavrio line from the homonymous square to Attica square was abolished and the starting point of the trains returned to the second.<ref name=":03">{{Cite book |title=Οι Ελληνικοί Σιδηρόδρομοι - Η διαδρομή τους από το 1869 έως σήμερα |publisher=Μίλητος |year= |isbn= |location=Αθήνα |pages=38–44}}</ref> At the same time, the construction of a new station in Piraeus began in the same year.<ref>{{Cite news |last=Ρηγόπουλος |first=Δημήτρης |date=12 December 2001 |title=Εκσυγχρονισμός και ιστορική μνήμη |url=https://www.kathimerini.gr/106923/article/politismos/arxeio-politismoy/eksygxronismos-kai-istorikh-mnhmh |work=[[Η Καθημερινή]]}}</ref> The new Piraeus station was inaugurated on 30 June 1928, the same day as the Kallithea station.<ref>{{Cite news |date=1 July 1928 |title=Τα χθεσινά εγκαίνια του σταθμού του ηλεκτρικού σιδηροδρόμου Πειραιώς |access-date= |work=Εμπρός |page=7 }}</ref>

The works of the first extension of the urban railway for over thirty years, started in January 1928. On 21 July 1930, the [[Omonia metro station|Omonia]] underground station was inaugurated by Prime Minister [[Eleftherios Venizelos]]. In 1937 HEM took over the electrification of the Kifissia railway and in 1938 it abolished Therio, to continue the work of extending the line to the north, however the war prevented the continuation of the works.

Finally, in 1948 the [[Victoria metro station, Athens|Victoria station]] was inaugurated and in 1949 the [[Attiki metro station|Attiki station]]. In 1950, HEM granted EIS the completion of the electrification project and the operation of the Athens-Kifisia railway. HEIS continued the works and in 1956 the stations [[Agios Nikolaos metro station|Aghios Nikolaos]], [[Kato Patisia metro station|Kato Patisia]] and [[Ano Patisia metro station|Ano Patisia]], [[Perissos metro station|Perissos]] and [[Nea Ionia metro station|Nea Ionia]] were delivered. At the beginning of 1957, the [[Irakleio metro station|Iraklio station]] was handed over, while on August 18 the line was connected to its terminus with the operation of the [[Kifissia metro station|Kifissia station]].<ref name=":12">{{Cite book |title=Οι Ελληνικοί Σιδηρόδρομοι - Η διαδρομή τους από το 1869 έως σήμερα |publisher=Μίλητος |year= |isbn= |location=Αθήνα |pages=32}}</ref> Now the urban railway, which had become known in public opinion as "Electric" (because of the electrification, in contrast to the older steam-powered "Thirio"), connected Piraeus with Kifissia. This was also the last kilometer extension of the line, but in the following years and decades the stations included increased, with the gradual addition of intermediate stations. Two weeks later, on 1 September, the [[Marousi station]] was handed over,<ref name=":12"/> while in 1961 [[Agios Eleftherios, Athens|Agios Eleftherios]] was inaugurated.<ref name=":22">{{Cite book |title=Οι Ελληνικοί Σιδηρόδρομοι - Η διαδρομή τους από το 1869 έως σήμερα |publisher=Μίλητος |year= |isbn= |location=Αθήνα |pages=33}}</ref>

In 1976, the Hellenic Electric Railways, fifty years after their establishment, were acquired by the Greek State and renamed the [[Athens–Piraeus Electric Railways|Athens-Piraeus Electric Railways]] (ISAP). In the 1980s, three intermediate (along the line) new stations were built: [[Eirini station]], designed to serve OAKA and opened on 3 September 1982<ref>{{Cite news |date=4 September 1982 |title=Σταθμός Ειρήνης στο Ολυμπιακό Στάδιο |work=[[Ριζοσπάστης]] |page=9}}</ref> the [[Tavros – Eleftherios Venizelos metro station|Tavros station]], inaugurated on 6 February 1989,<ref>{{Cite news |date=12 February 1989 |title=Νέος σταθμός στον Ταύρο |access-date= |work=[[Το Βήμα]] |page=27 }}</ref> and that of [[KAT metro station|KAT]], which was built with the aim of serving the [[KAT Hospital|adjacent hospital]] of the same name and was inaugurated on 27 March 1989.

Between 2001 and 2004, in view of the [[2004 Summer Olympics|2004 Olympic Games]], an extensive program of renovations of all the stations of the line took place, while between 2008 and 2011, reconstruction works were carried out on the railway line from [[Neo Faliro]] to [[Kifisias railway station|Kifissia]]. Also, the [[Neratziotissa station|Neratziotissa]] station was built, which allows transfers from Line 1 to the [[Proastiakos|Suburban network]].<ref>{{Cite news |date=6 August 2004 |title=Νερατζιώτισσα, Κακιά Σκάλα, Αττική οδός |url=https://www.kathimerini.gr/190718/article/epikairothta/ellada/neratziwtissa-kakia-skala-attikh-odos |work=[[Η Καθημερινή]]}}</ref>

In 2011, ISAP SA became a subsidiary company of OASA<ref>{{Cite web |date=2012-01-01 |title=ISAP - Athens Piraeus Electric Railways |url=http://www.isap.gr/eng/page.asp?id=42 |url-status=unfit |archive-url=https://web.archive.org/web/20120101152221/http://www.isap.gr/eng/page.asp?id=42 |archive-date=2012-01-01 |access-date=2019-08-29 }}</ref> was absorbed, together with TRAM SA, by AMEL SA, which was renamed [[STASY]] SA.

== Network ==

Line 1 connects the port of Piraeus with the northern suburb of [[Kifissia]]. It is built to {{RailGauge|sg|al=on}} and is electrified using the 750 V DC, third rail, top contact system, also used by Lines 2 and 3.

From Piraeus the line runs eastwards to Faliro and then north to Moschato, Kallithea, Tavros, Petralona, Thissio, Monastiraki, Omonia, Victoria and Attiki. Between Monastiraki and Attiki the line runs underground. At Monastiraki passengers can change to [[Line 3 (Athens Metro)|Line 3]] and at Omonia and Attiki to [[Line 2 (Athens Metro)|Line 2]]. From Attiki the line continues north, following the alignment of the old [[Lavrion Square-Strofyli railway]] through Patissia, Nea Ionia, Iraklio, Marousi and terminates at Kifissia. At Nerantziotissa station passengers can change to the [[Athens Suburban Railway]], for [[Athens International Airport]].

Line 1 has a physical connection to Line 2 at Attiki station.

=== Other proposed extensions ===

==== Kaminia, Ilissos and Psalidi stations ====

In November 2008, [[Athens–Piraeus Electric Railways|ISAP]] proposed three new stations along the existing Line 1. they were: Kaminia, located next to Kerani Square,<ref name="ametro-tram">{{cite web|title=Tramway works in Piraeus - Phase A'|url=http://www.ametro.gr/files/imagestram/AM_TRAM_Piraeus_Map_Nov12_en_LG.jpg|website=Attiko Metro|access-date=30 March 2025|archive-url=http://arquivo.pt/wayback/20160515150145/http://www.ametro.gr/files/imagestram/AM_TRAM_Piraeus_Map_Nov12_en_LG.jpg|archive-date=15 May 2016|location=Athens|language=en-gb|date=November 2012|url-status=dead}}</ref> and between Piraeus and Neo Faliro; Ilissos, between Moschato and Kallithea; and Psalidi, between Iraklio and Eirini.<ref name="isap-20081113">{{cite web|title=Ο ΗΣΑΠ … ανανεώνεται … εκσυγχρονίζεται … επεκτείνεται|trans-title=ISAP … renewed … modernized … expanded|url=http://www.isap.gr/filesup/ISAP_EKSIXRONISMOS.pdf|website=Athens–Piraeus Electric Railways|access-date=30 March 2025|archive-url=https://web.archive.org/web/20091228212229/http://www.isap.gr/filesup/ISAP_EKSIXRONISMOS.pdf|archive-date=28 December 2009|location=Athens|pages=4–7|language=el|date=13 November 2008|url-status=dead}}</ref> All three stations were also included in the Souflias plan.<ref name="ametro-futuremap-2009"/>

== Accidents ==

=== Incidents of People falling on the rail tracks === Either by accident or on purpose (e.g. [[rail suicide]]) it is unfortunately rather common. On 29 July 2022 a man fell on the tracks of Ano Patissia with the tracks temporarily shutting down as the police and medics were assessing the situation. On 26 May 2024 a person fell on the tracks of line 1 in the station of [[Nea Ionia metro station|Nea Ionia]] where police vehicles and ambulances were sent to analyse the situation, with the tracks shutting down temporarily. In October of the same year the same event happened in a pedestrian bridge near [[KAT metro station|KAT station]]. In December of the same year the same event happened with a man falling off a pedestrian bridge near [[Ano Patisia metro station|Ano Patissia]] onto the tracks below him where medics were sent to recover him delaying the tracks almost 7 minutes. On 13 January 2025 a 69-year-old man fell off the station of [[Agios Eleftherios metro station|Aghios Eleftherios]] halting the schedules and being found dead by [[Hellenic Police|ELAS]].<ref name=":6" /><ref name=":2">{{Cite web |date=2024-04-26 |title=Νέα Ιωνία: Άτομο έπεσε στις γραμμές του ΗΣΑΠ {{!}} LiFO |url=https://www.lifo.gr/now/greece/nea-ionia-atomo-epese-stis-grammes-toy-isap |access-date=2025-01-28 |website=www.lifo.gr |language=el}}</ref><ref name=":3">{{Cite web |date=2024-10-16 |title=Νεκρός ο άνδρας που έπεσε από πεζογέφυρα στο ΚΑΤ |url=https://www.tovima.gr/2024/10/16/society/isap-ptosi-atomou-apo-pezogefyra-sto-kat-diakopikan-ta-dromologia/ |access-date=2025-01-28 |website=ΤΟ ΒΗΜΑ |language=el}}</ref><ref name=":4">{{Cite web |date=2024-12-19 |title=Άτομο έπεσε από πεζογέφυρα του ΗΣΑΠ στα Ανω Πατήσια |url=https://www.tovima.gr/2024/12/19/society/ano-patisia-atomo-epese-apo-pezogefyra-tou-isap/ |access-date=2025-01-28 |website=ΤΟ ΒΗΜΑ |language=el}}</ref><ref name=":5">{{Cite web |date=2025-01-13 |title=Νεκρός ο άνδρας που έπεσε στις γραμμές του ΗΣΑΠ στον Άγιο Ελευθέριο |url=https://www.tovima.gr/2025/01/13/society/isap-ptosi-atomou-stis-grammes-pou-exei-ginei-diakopi-kykloforias/ |access-date=2025-01-28 |website=ΤΟ ΒΗΜΑ |language=el}}</ref> {| class="wikitable" |+ !Place !Date !Notes !References |- |[[Ano Patisia metro station|Ano Patissia]] |29 July 2022 | |<ref name=":6">{{Cite web |date=2022-07-29 |title=ΗΣΑΠ: Πτώση ατόμου στις ράγες στα Άνω Πατήσια - Κυκλοφορία μεταξύ των σταθμών Πειραιά-Αττική και Ν.

=== Other Incidents === On 16 November 2021 a train near the station of [[Agios Nikolaos metro station|Aghios Nikolaos]] collided with a group of workers on a machine used for sanding the tracks, killing one and injuring 2 of the workers working there. On 25 September 2024 the tracks between the stations of [[Neratziotissa station|Neratziotissa]] and [[Eirini metro station|Eirini]] caught on fire due to dry fallen trees, firefighters were quickly dispatched, the train halted and the passengers quickly got off with no injuries. On 1 January 2025 the first train scheduled for 2025 malfunctioned having its doors on one side of the train open while in motion between the stations of [[Ano Patisia metro station|Ano Patisia]] and [[Perissos metro station|Perissos]] this took place just 2 days after another incident where in the station of [[Moschato]] the tracks started releasing an alarmingly dense amount of smoke. The Unionized workers of [[STASY]] released a statement saying "Every day that dawns on Line 1 the workers cross their fingers[...]". Just a month later on 31 January in the same station of [[Moschato]] the same event happened in the same fashion with officials stating that it may have been caused by a malfunction, most likely, during the use of the breaks.<ref name=":7">{{Cite web |last=Group) |first=Radiotileoptiki S.

The spelling of the station names on this table, in English and Greek, are according to the signage.

The layout of Line 1 stations have some variety, compared to the other two lines on the system (including the upcoming [[Line 4 (Athens Metro)|Line 4]]).
