Editing Proastiakos (section)

==Future plans==
{{unreferenced section|date=August 2017}}
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, the 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:

*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 Suburban Railway and Athens-Chalkis trains. The slow lines are under construction.
*[[Pyrgos Vasilissis railway station|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|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 - 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, where existing infrastructure for a possible extension is already in place.

New stations will be built at:
*[[Markopoulo Mesogaias|Markopoulo]]
*[[Kalyvia Thorikou|Kalyvia]]
*[[Kouvaras]]
*[[Keratea]]
*[[Kalopigado]]
*[[Thoricus|Thoriko]]
*[[Laurium|Lavrio]]
*[[Port of Lavrio]]
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 upon inauguration. <ref>{{Cite web |last=Καραγιάννης |first=Νίκος |date=2021-12-13 |title=Αθήνα-Λιμάνι Λαυρίου σε 50 λεπτά με την επέκταση του Προαστιακού Σιδηροδρόμου στο Λαύριο |url=https://ypodomes.com/athina-limani-layrioy-se-50-lepta-me-tin-epektasi-toy-proastiakoy-sidirodromoy-sto-layrio/ |access-date=2022-03-19 |website=Ypodomes.com |language=el}}</ref>

===Section:  SKA – Pallini - Rafina ===
Future services to Rafina will be on new lines, currently{{when|date=August 2017}} 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 / Aigio / Patras / Loutraki===
The existing line to Kiato has been extended to Aigio. The extension to Patras is under construction. A branch line to Loutraki is under construction.
* [[Zefyri]]: A new station to serve a future sports center.
* [[Xylokastro]]: New station with two platforms and pass-through line.
* [[Aigio]]: New station with three platforms.
* Loutraki branch:
**[[Isthmus of Corinth|Isthmos]]
**[[Loutraki]]

===Section: SKA – Halkida / Thiva===
These stations are on the existing mainline and are served by regional and mainline trains. They shall be served by Proastiakos suburban trains in the future, when electrification and adequate line capacity are available between Athens and SKA.
