Proastiakos
commuter rail service in Greece

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.
As of 8 January 2017, the lines between the central stations of Athens and Halkida have been electrified, allowing EMU train service. The lines have been changed, making Athens's central station the main layover station. Those lines are Athens – ATH, Athens – Kiato, Athens – Chalcis.
In Thessaloniki, there are two Proastiakos services. The first connects the city's Main Railway Station with the cities of Katerini and Larissa, and the second links the city with Edessa.
In July 2010, a new commuter rail service was launched in Patras on a section of the old Patras–Kyparissia line reconnecting the city with Rio.
This brief starts where responsible research should: with the source description of “Proastiakos” as commuter rail service in Greece. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as commuter rail service in Greece. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 15, 2026. The linked authority identifier is Q2008811. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2020, 2016, 2017 and 2010.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
