# Line A4 (Athens Suburban Railway)

Line A4 is an Athens Suburban Railway (Proastiakos) line in Athens, Greece, managed by Hellenic Train. The service connects Piraeus with the coastal city of Kiato. The line shares a part of its course with lines A1 and A3 as well as Metro line 2, but also with line A3 at Ano Liosia. 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

An indirect standard gauge train service between Athens and Corinth started on 27 September 2005 after seven months of testing, with the extension to Kiato following on 9 July 2007. The service initially used Class 560 diesel multiple units, and had to reverse at Neratziotissa.
The first direct trains between Piraeus and Kiato, which did not have to reverse at Nerantziotissa, ran on 6 July 2008. From 12 December 2010 to 29 July 2017, electric train services using Class 460 electric multiple units were introduced between Kiato and the Airport, forcing passengers heading to and from Piraeus and Athens to change at Ano Liosia for the diesel service to the cities.
Direct services between Athens and Kiato 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 A4 ceased.

## Route

On the Piraeus–Platy segment, Lines A1 and A3 shares the route up to Piraeus and Athens respectively, but Line A3 does not stop at Kato Acharnes and Pyrgos Vasilissis.
