Line 1 (Athens Metro)

Line 1 is the oldest of the three lines of the Athens Metro, running from Kifissia to. The Athens-Piraeus Railway Company (SAP S.A.) first opened the line, between and, on 27 February 1869. On 4 February 1885 Lavrion Square-Strofyli railway line opened between Attiki Square and Kifissia. These railway lines gradually merged and converted to a rapid-transit system. It was merged into the Athens Metro network upon the opening of Lines 2 and 3 on 28 January 2000.

Network


Line 1 connects the port of Piraeus with the northern suburb of Kifissia. It is built to 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 and at Omonia and Attiki to 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.

Extension towards Nea Erythraia
Since 2008, ISAP S.A., and subsequently STASY S.A., proposed a two-phase northern extension of Line 1 from Kifissia to Agios Stefanos, via Ethniki Odos (Athinon-Lamias) near Ekali, bringing the Dionysos municipality into the Athens Metro catchment area.

The first phase includes new stations at AOK, Nea Erithrea, Athens Metro and Ethniki Odos, but requires the reconstruction of Kifissia into an underground station. The second phase would be mostly sub-surface, with new stations at Anixi and Agios Stefanos.

The project was dropped by the company late in 2011 due to lack of funding and incomplete feasibility data.

Extension towards Palaio Faliro
Plans to extend Line 1 from Thiseio to the Stavros Niarchos Foundation Cultural Center in Kallithea originated as part of the southern branch of Line 6 in the long-term Athens Metro Future Regulatory Plan (or the Souflias plan) of April 2009: the proposal would have seen trains from the SNFCC to Melissia in the north east, and Idreika in the Piraeus peninsula.

Proposals for this line saw little activity from January 2012 to December 2021, when it was partially reconsidered as a branch of Line 1 from Thiseio to the SNFCC, with intermediate stations at Hamosternas, Plateia Davaki, and Lofos Filaretou. Attiko Metro also announced the possibility of a further extension towards Palaio Faliro, along Amfitheas Avenue, instead of Idreika.

Kaminia metro station
In 2012, Attiko Metro S.A. included Kaminia metro station in the Athens Regulatory Plan. The new station will be sited near Kerani Square, between Piraeus and Neo Faliro.

Psalidi metro station
In 2012, Attiko Metro S.A. included Psalidi metro station in the Athens Regulatory Plan. The new station will be sited between Iraklio and Eirini.

Other proposed extensions
The Souflias plan of April 2009 also included a proposal to extend Line 1 from Faliro to Drapetsona and Amfiali (in Keratsini), with a new underground station for Piraeus.

Stations
The spelling of the station names on this table, in English and Greek, are according to the signage. The list also runs from south to north, because the former Athens–Piraeus Electric Railways measured all distances from Piraeus.

The layout of Line 1 stations have some variety, compared to the other two lines on the system (including the upcoming Line 4). Although most stations have two tracks and two side platforms, four stations (Eirini, Faliro, Omonia and Piraeus) have a Spanish solution layout of two tracks and three platforms, Tavros – Eleftherios Venizelos has an island platform, and Kifissia has a bay platform with a second track on the western side of the platform.
