Line A2 is an Athens Suburban Railway (Proastiakos) line in Athens, Greece, managed by Hellenic Train. The service connects Ano Liosia railway station with the Airport. The line shares a part of its course with lines A1 and A4 as well as Metro Line 3, but also with line A3 at Acharnes Railway Center. The first Suburban line was inaugurated on 30 July 2004, using 17 OSE Class 560 DMUs between Larissa Station (Now Athens) and the Airport, ^[2] and although it is shown as a separate route on maps, it currently operates as a feeder line to Line A1. The line now exclusively uses OSE class 460 EMUs rolling stock.

History

Line A2 is a remnant of a standard gauge suburban railway service that ran between Athens Airport and Kiato. The first section of the service between the Airport and Corinth, using Class 560 diesel multiple units, opened on 27 September 2005: ^[3] the western extension to Kiato followed on 9 July 2007. ^[4]

Direct train services between Ano Liosia (the current western terminus of Line A2) and the Airport began on 18 July 2006, with the opening of Ano Liosia station on the Airport–Patras railway. ^[5] Due to electrification works, the Airport–Kiato service was split from 6 July 2008 to 12 December 2010, after which the entire service was served by electric trains using Class 460 electric multiple units. ^{[6] [7]}

On 30 July 2017, due to the restructuring of suburban railway services associated with the introduction of electric trains to Athens railway station and (since 2018) Piraeus, the direct Airport–Kiato service was replaced by the SKA–Airport shuttle, effectively reinforcing the median strip section of Line A1. ^[8] On 24 February 2018, the western end of what is now Line A2 was extended to Ano Liosia. ^[9]

Route

Line A2 runs between Ano Liosia and Athens Airport, along the median strip of the A6 and A64 motorways. Since 22 November 2025, there are up to two trains per hour on weekdays, and up to one train per hour on weekends and public holidays. ^[10]

Line A2 practically reinforces parts of Line A1 and Athens Metro Line 3, from the Airport up to Metamorfosi and Pallini respectively. However, most Metro Line 3 trains start or terminate at Doukissis Plakentias (an interchange with Lines A1 and A2 at Plakentias) with a through service to the Airport leaving Piraeus once every 36 minutes. ^[11]
