Athens Suburban Railway in the context of "Kiato railway station"

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.

Line 3 of the Athens Metro is a rapid transit line that runs from Dimotiko Theatro in the west to Doukissis Plakentias or Athens Airport in the east, via Syntagma. Most Line 3 trains start or terminate at Doukissis Plakentias: a through service to the Airport leaves once every 36 minutes, and shares most of the extended route with the Athens Suburban Railway. It runs for 47.3 kilometres (29.4 mi), making it the system's longest line.

Line 3 provides a direct albeit infrequent service between the Port of Piraeus with the Athens International Airport, a journey that takes up to 59 minutes. The line between Dimotiko Theatro and Doukissis Plakentias is underground, and the shared section with the Athens Suburban Railway towards the Airport is a surface-level median of the A6 and A64 motorways.

The Athens Metro (Greek: Μετρό Αθήνας, romanized: Metro Athinas) is a rapid transit system serving the Athens urban area in Greece. Line 1 opened as a single-track conventional steam railway in 1869 and was electrified in 1904. Beginning in 1991, Elliniko Metro S.A. constructed and extended Lines 2 and 3. It has significantly changed Athens by providing a much-needed solution to the city's traffic and air pollution problem, as well as revitalising many of the areas it serves. Extensions of existing lines are under development or tender, like the Line 2 extension to Ilion where tender started in 2023, as well as a new Line 4, whose central section began construction in October 2021.

The Athens Metro is actively connected with the other means of public transport, such as buses, trolleys, the Athens Tram and the Athens Suburban Railway. The Athens Metro is hailed for its modernity (mainly the newer lines 2, 3), and many of its stations feature works of art, exhibitions and displays of the archaeological remains found during its construction. Photography and video-taking is permitted across the whole network and street photographers often work in Athens Metro. This was the only metro system in Greece, before the Thessaloniki Metro began operations on 30 November 2024.

Kato Achaia (Greek: Κάτω Αχαΐα) is a town and a community in Achaea, West Greece, Greece. Since the 2011 local government reform it is part of the municipality West Achaea, of which it is the seat of administration. The community Kato Achaia consists of the town Kato Achaia and the villages Alykes, Manetaiikia, Paralia Kato Achaias and Piso Sykea. Nearby are the ruins of the ancient city of Dyme.

Kato Achaia is located 1 km (0.6 mi) south of the Gulf of Patras and 20 km (12 mi) southwest of Patras. The villages Alykes and Paralia Kato Achaias are on the coast. The Greek National Road 9 (Patras - Pyrgos) passes outside the town. Kato Achaia has a train station on the partly disused Patras–Pyrgos railway. Currently, train traffic is somewhat offered through the Patras Suburban Railway between Rio-Patras and Kaminia, while the last stretch of the journey is made by buses ran by Hellenic Train, that make two stops at the two temporarily offline stations of Alissos and Kato Achaia. In the future, the railway will restart operations towards Pyrgos and also provide connection with the Intercity Railway network.
