The Proastiakos (Greek: ; "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.
Photography and videography is permitted across the entire Proastiakos network; however, the security personnel may often prohibit camera usage.
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 of Athens consists of 4 routes Athens - Airport , Athens - Kiato , Athens - Chalkida and Ano liosia Station - Airport:
|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|
The suburban railway connects with the other urban railways of Athens in the following stations:
|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 - Katerini - Thessaloniki||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:
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. Trains run daily from 6:23 in the morning until 23:23 in the evening. The Proastiakos in Patra is considered to be the most popular Proastiakos service in Greece.
The following table lists the routes and the stations for the Proastiakos line of Patras is:
|Route||First section opened||Latest section opened||Latest station opened||Route||Length (km, mi)||Stations|
|A||9 July 2010||Agios Andreas - Agios Vasileios||12.5 km (7.8 mi.)||8|
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 (EUR1,40), 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 EUR8 (7.9 on line) and a return ticket EUR16 (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.
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.
A number of new stations and halts are under construction on this line and they shall be served by Proastiakos trains:
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.
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:
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.
