The Proastiakos (Greek: Προαστιακός; "suburban") is the collective name for Greece's suburban railway (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.

As of 8 January 2017, the lines between central station of Athens and Halkida have been electrified allowing EMU train service. The lines have been changed making the central station of Athens 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 New 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, connecting the city with Rio.

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 27 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 Central Station 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 9 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 AthensEdit

Proastiakos of Athens consists of 4 routes Athens – Airport , Athens – Kiato , Athens – Chalkida and Ano liosia Station – Airport:

Proastiakos routes
Route Route length (km) Route Stations
1 48,2 Piraeus - Athens - Airport 19
2 122 Piraeus - Athens - Kiato 20
3 82,7 Athens - Oinoi - Chalcis 19
4 29,7 Ano Liosia - S.K.A - Airport 11
  • An early morning service from Athens Station to Tithorea is also considered a Proastiakos service. There are plans to add more trains during the day so that a regular commuter service can be established on the line, which is currently served almost exclusively by intercity services with most stations receiving a limited number of trains daily.
  • A new Proastiakos line linking Athens Station and the Airport is due to begin operations in December 2017, using existing lines and the newly installed electrification of the line that leads into Athens Station. In August the electrification works have been completed along the partial length of the line as far as Athens and services are extended to that station. The stops and service patterns of the initial services from Athens to the Airport have been announced. The extended services will be announced in December.


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

Proastiakos ThessalonikiEdit

Proastiakos of Thessaloniki consists of two routes: one from Thessaloniki to Larissa and one from Thessaloniki to Edessa.[citation needed] 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:

Proastiakos routes
Route Elec. First section opened Latest section opened Latest station opened Route Length (km, mi) Stations
Pieria Line 2007 7 September 2007 Katerini - Litochoro 7 September 2008 7 September 2008 (Larissa) Larissa - KateriniThessaloniki 165.2 km (103 mi.) 12
Imathia-Pella Line 25 January 2008 10 August 2013 10 August 2013 (Florina) Thessaloniki - Florina 156.4 km (71.3 mi.) 22


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

  • Thessaloniki: future connection to Thessaloniki Metro
  • Platy: passengers can transfer to the regional rail service of Western Macedonia (towards Verroia, Edessa, Amyntaio, Florina and Kozani).
  • Larissa: passengers can transfer to the mainline and regional rail service as well as trains to Volos.

Proastiakos PatrasEdit

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.[4] Trains run daily from 6:23 in the morning until 23:23 in the evening.[4]

The following table lists the routes and the stations for the Proastiakos line of Patras is:

Proastiakos routes
Route First section opened Latest section opened Latest station opened Route Length (km, mi) Stations
A 9 July 2010 Agios AndreasAgios Vasileios 12.5 km (7.8 mi.) 8
  • By the end of July 2017 an extension from Aghios Andreas to Kato Achagia.

Rolling stockEdit

Proastiakos uses rolling stock owned and maintained by OSE S.A. Currently[when?] multiple units are used almost exclusively. Siemens Desiro 5-car electric multiple units (EMU) are used for Piraeus - Athens - Airport , Piraeus - Athens - Kiato , Athens – Chalkis and Thessaloniki - Larisa services, while Stadler GTW-2/6 and MAN-2000 diesel two-car multiple units (DMU-2) are used for the 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 central Athens to the Airport costs €8 (7.9 on line) and a return ticket €16 (15.5 on line).

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 plansEdit

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:

  • Construction of a three or four track line between Rouf and SKA stations.
  • Electrification of lines between Piraeus and SKA.
  • Installation of signalling on lines between Piraeus and SKA.
  • Construction of ten passenger platforms and one "through track" at Athens Central station.
  • Construction of new stations at Tavros, Pyrgos Vasilissis, Lykotrypa and Zevgolatio.

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.Edit

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

  • Tavros
  • Athens (Athens Central Railway Station): The station is extended with new platforms to serve future suburban services. Completed as of August 2017.
  • Agioi Anargyroi: New four platform station served by mainline and suburban trains, plus a freight siding. The fast line platforms are already operational and are served by Proastiakos and Athens-Chalkis trains. The slow lines are under construction.
  • Pyrgos Vasilissis: Is open after the slow lines between Agioi Anargyroi and SKA are operational.
  • Lykotrypa: Is open after the slow lines between Agioi Anargyroi and SKA are operational.
  • Acharnai Railway Center (SKA): The station is partly open since 2011-04-05, extensive work is still required to finish the first phase of the complex.

Section: SKA – Koropi - LavrioEdit

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 - RafinaEdit

Future services to Rafina will be on new lines, currently[when?] securing funds. 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:

  • Pikermi
  • Kallitechnoupoli
  • Rafina

Section: SKA – Corinth / Kiato / Xylokastro / LoutrakiEdit

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.

  • Zefyri: A new station planned to serve a future sports center, if built in the area.
  • Xylokastro: Extension to Xylokastro is under construction.
  • Loutraki branch:
