Athens International Airport
Proastiakos is a relatively new development, with the first service inaugurated for 2004 Athens Olympic Games, between Athens International Airport and Athens (via Neratziotissa station, close to the Olympic Stadium). The commuter rail services that are currently operated by Proastiakos include the lines on the 'main corridor' of Piraeus–Athens–Ano Liosia, Ano Liosia–Athens International Airport, Ano Liosia–Corinth–Kiato; and between the cities of Thessaloniki and Larissa.
