# Line A1 (Athens Suburban Railway)

Line A1 is an Athens Suburban Railway (Proastiakos) line in Athens, Greece, managed by Hellenic Train. The service connects Piraeus with the Airport. The line shares a part of its course with lines A2 and A4 as well as Metro line 3, but also with line A3 at Athens. The first Suburban line was inaugurated on 30 July 2004, using 17 OSE Class 560 DMUs between Larissa Station (Now Athens) and the Airport. With the completion of the electrification of the sections of the line to Athens in 2017 and Piraeus in 2018. The line now exclusively uses OSE class 460 EMUs rolling stock.

## History

The initial planning phase of the service provided for the use of express trains (Airport Express) from Piraeus to the Airport with intermediate stations only in Athens, Agioi Anargyroi, Neratziotissa, Kifissias and Dukisis Placentias, and with a journey time of half an hour. In the end, however, the need to connect the capital's international airport with the city's most central station, Syntagma, imposed the joint travel of Suburban and Metro from Doukissis Plakentias to the Airport.
The first section of what is now Line A1 opened on 30 July 2004: the standard gauge service ran from Athens to the Airport, using Class 560 diesel multiple units. Electric train services using Class 460 electric multiple units were introduced between Neratziotissa and the Airport in 2006. On 4 June 2007, diesel services were extended south from Athens to Piraeus, replacing the relevant part of the metre-gauge railway of the Piraeus–Patras railway that closed in August 2005.
Direct suburban railway services from Piraeus and Athens to the Airport were suspended on 6 July 2008, forcing passengers to change at Ano Liosia and (until 14 February 2009) Neratziotissa. Direct services were restored with the electrification of the Piraeus–Platy railway from Agioi Anargyroi to Athens on 30 July 2017, and then to Piraeus on 1 February 2018, when the last diesel services on what is now Line A1 ceased.

## Route

On the Airport–Patras segment, Lines A2 and Athens Metro Line 3 shares the route from the Airport up to Metamorfosi and Pallini respectively. However, most Metro Line 3 trains start or terminate at Doukissis Plakentias, with a through service to the Airport leaving once every 36 minutes.
