Athens Airport (Greek: Αεροδρόμιο, Aerodromio), also known as Athens International Airport (Διεθνής Αερολιμένας Αθηνών, Diethnis Aerolimenas Athinon) on signage, is a railway station and metro station that serves the international airport of Athens, Greece. It operates on both the Athens Suburban Railway as well as Line 3 of the Athens Metro. It is the first and only train station in Greece that is not managed by GAIAOSE. It is owned by the airport, which charges the train operating companies (Hellenic Train and STASY) fees for its use.
The Proastiakos (Greek: Προαστιακός; "suburban") is Greece's commuter rail service, run by Hellenic Train, on rail infrastructure owned by the Hellenic Railways Organisation (OSE) (lines) and GAIAOSE (buildings and Trains). These services connect a participating city's central railway station to important locations such as a city's port or airport, as well as its suburbs and occasionally nearby towns and cities.
As of September 2020, there are three Proastiakos networks serving the country's three largest cities: Athens, Thessaloniki, and Patras, providing them with commuter rail links towards their suburbs and also with regional services to other cities and towns. In 2016, the three systems carried 10.1 million passengers.
