The Proastiakos (Greek: Προαστιακός, English: 'suburban') is the collective name for Greece's suburban (commuter rail) services, which are run by TrainOSE, the country's only rail operator, on infrastructure owned by the Hellenic Railways Organisation (OSE).

As of March 2016 there are three Proastiakos networks, servicing 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 Athens, the Proastiakos offers a direct connection between Athens International Airport and Kiato, in the Peloponnese. The service also connects the port of Piraeus with Halkida in Evia, through Athens Railway Station, which is more commonly called Stathmos Larisis.

In Thessaloniki, there are two Proastiakos services. The first connects the city's New Railway Station with the city of Larissa and the second links the city with Edessa.

In July 2010 a new commuter rail service was launched in Patras, connecting the city with Rio.

Photography and video-taking is permitted across the whole Proastiakos network, however very often the security personnel might create problems to photographers.[1]


The term Proastiakos, which translates as "suburban", is derived from the ancient Greek word "proasteion" (suburb, προάστειον), "pro + asty (προ-άστυ)" meaning "before the city". However the same brand name has also been used for some regional rail services.


The concept of a regular and frequent suburban and commuter rail services was introduced in Greece in the 1990s. It became possible due to extra capacity becoming available through improvements to the existing lines and the construction of new ones. In the past suburban services ran on very infrequent timetables and were not very popular.

The construction of a new rail line between central Athens, its eastern suburbs and the new Athens International Airport was decided in 1992-1993. During the construction of Attiki Odos motorway in the late 1990s, space was left between the main carriageways for the railway line and after two years of construction, the line to Athens International Airport opened in 2004. The first suburban services between Athens and the Airport were inaugurated using Stadler GTW and Siemens Desiro DMU trains.

On the 27th of September 2005, the new standard gauge rail line reached Corinth, terminating at a new station, located at Examilia. This line today is served by "Proastiakos" suburban services, while initially "Proastiakos" trains stopped at Nea Peramos, Megara, Kinetta and Agioi Theodoroi. On 18 July 2006 three new stations were added: Ano Liosia, Aspropyrgos and Magoula. On 4 June 2007 the line was extended from Athens to the port of Piraeus with 3 intermediate stations at Lefka, Rentis and Rouf. This extension linked the airport with the port of Piraeus. On the 9th of July 2007, Proastiakos services reached the new station at Kiato.

TrainOSE also runs "Proastiakos" commuter rail services between the cities of Thessaloniki and Larissa, on the modernised and electrified main line. The service initially operated from Thessaloniki to Litochoro in 2007 and was extended to Larissa in 2008.

In 2009 the brand name "Proastiakos" was also used for a short-lived regional service of four trains in each direction per day, connecting the cities of Xanthi, Komotini and Alexandroupolis in the region of Western Thrace.

Proastiakos Athens

Proastiakos of Athens consists of two routes: one from Piraeus to Chalcis with a branch to Ano Liosia and one route from Kiato to the Airport. Trains run from approximately 5:00am to midnight daily.[2][3] There are 44 stations in total.

The following table lists the routes and the stations for the Proastiakos network of Athens (correct to 20 April 2014):

The suburban railway connects with the other urban railways of Athens in the following stations:

Proastiakos Thessaloniki

Proastiakos of Thessaloniki consists of two routes: one from Thessaloniki to Larissa and one from Thessaloniki to Edessa. Trains run from approximately 5:00am to midnight daily.[2][3]

The following table lists the routes and the stations for the Proastiakos network of Thessaloniki, Larissa and Florina is:

The Proastiakos service towards Kiato also connects to the following long distance and regional rail services:

The Proastiakos service towards Larissa also connects to the following long distance and regional rail services:

Proastiakos Patras

Suburban rail in Patras

Proastiakos of Patras consists of just one route from Agios Andreas station to the western suburb of Agios Vasileios with a bus service from Kastellokampos to the Patras University Hospital and the University of Patras campus.[8] Trains run daily from 6:23 in the morning until 23:23 in the evening.[8]

Rolling stock

Proastiakos uses rolling stock owned and maintained by OSE S.A. Currently multiple units are used almost exclusively. Siemens Desiro 5-car electric multiple units (EMU) are used for Ano Liosia-Airport, Airport-Kiato and Thessaloniki-Larisa services, while Stadler GTW-2/6 and MAN-2000 diesel two-car multiple units (DMU-2) are used for the Piraeus-Ano Liosia and Patras-Rio services. As these DMUs have limited passenger carrying capacity, two or three DMUs are coupled together, when rolling stock availability allows it.


Standard tickets (€1,40), valid on all urban buses and trains, are also valid on Proastiakos trains between Piraeus, SKA, Koropi and Magoula. Higher fares apply for travel to the Airport, between Magoula and Kiato; and between Thessaloniki and Larisa. A one-way ticket from Piraeus or Athens to the Airport costs €10 and a return ticket €18.

Tickets must be validated on special ticket validation machines on the platform, before boarding the train. Return tickets must be re-validated before boarding a return train. There are no ticket validation machines on the trains.

Future plans

Addition of new routes and stations to Proastiakos services depends on the progress of a number of OSE infrastructure projects in Attica. The most important projects are:

As of April 2011, introduction of new and more frequent services is mainly hindered by limited line capacity between Rouf and SKA; and limited availability of diesel rolling stock for the non-electrified line.

Section: Piraeus – S.K.A.

A number of new stations and halts are under construction on this line and they shall be served by Proastiakos trains:

Section: SKA – Koropi - Lavrio

The extension to Lavrio will mostly follow the alignment of the old Athens to Lavrio metric gauge line, which closed to passengers in 1957 and to goods in 1962. Most of the old alignment is still intact, and several bridges, all station buildings as well as the tracks themselves on many locations, are still in situ, but will need to be replaced as they were designed for a single metric gauge line, while the new one will be standard gauge and double-track for most of its length. The new line will branch off the airport line just beyond Koropi station. New stations will be built at

at or near the same site as their predecessors, the buildings of which, most of them listed structures, will hopefully be preserved. The line will be electrified from the outset.

Section: SKA – Pallini - Rafina

Future services to Rafina will be on new lines, currently under consideration. The line to Rafina shall branch off after Pallini station and will partly run on the central reservation of the Hymittus Ring Road. The stations will be:

Section: SKA – Corinth / Kiato / Xylokastro / Loutraki

The existing line to Kiato is being extended to Xylokastro, which shall be the final destination of suburban trains. A branch line to Loutraki is under consideration but is delayed due to reactions by the local authority.
