Line 1 is the oldest of the three lines of the Athens Metro, running from Kifisia to Piraeus. The Athens-Piraeus Railway Company (SAP S.A.) first opened the line, between Piraeus and Thiseio, 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 and stations
Line 1 connects the port of Piraeus with the northern suburb of Kifissia. It is built to 1,435 mm (4 ft 8+1⁄2 in) standard gauge 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 suburban railway serving Athens International Airport.
Line 1 has a physical connection to Line 2 at Attiki station.

Proposed extensions and stations
Northern Extension to Agios Stefanos
Since 2008, ISAP S.A., and subsequently STASY S.A., proposed a two-phase northern extension of Line 1 from Kifisia 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, Ekali and Ethniki Odos, but requires the reconstruction of Kifisia 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.
Western Extension to Amfiali
In 2012, Attiko Metro S.A. included the western extension from Piraeus to Amfiali in the Athens Regulatory Plan.
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.
