As of 2019 the station is served by eight trains per day to Thessaloniki, one train per hour between the Airport and Ano Liosia, one train per hour between Koropi and Ano Liosia, and one train per 2 hours between Athens and Chalcis.
Platforms
The station has 8 platforms, as well as one low-level platform in the median of Attiki Odos Motorway. Currently, only this platform and two others are used.
Future
Usage of the 7 remaining platforms Apart from the 2 platforms on the Athens to Thessaloniki Line and the Proastiakos platform low level platform, the station has 6 platforms that remain unused. Those platforms exist in order to accommodate future services, especially after the completion of the P.A.Th.E./P..
Platforms 1 and 2, which serve tracks 1, 2, 3 and 4 respectively, will open after the completion of the Athens to Patras line. Trains go through these tracks daily, however they do not call at the station. The Athens to Patras line has already been completed as far as Aigio. The next sections are under construction and will open in stages from 2020 onwards.
Platforms 3 and 4 serve tracks 5, 6, 7 and 8. They will be used in case the Acharnes Bypass is completed. If completed, intercity and regional will be redirected through a tunnel, bypassing Acharnes, that will allow them to reach higher speeds, thus reducing travel times. Construction of this bypass seemed likely because the line north of Athens is expected to suffer from capacity issues and become a major bottleneck in the Greek Rail Network. Lack of finance as well as another proposal with the same goal, the Thriasion - Thiva Line have put this project on hold.
Platforms 5 and 6, which serve tracks 9, 10 and 11 are terminating platforms. Usage of these platforms is highly unlikely because extending services further from the station instead of having them terminate there is more favourable because of financial reasons, as well as the fact that they would attract more passengers.
Metro Station
A future station has been proposed on line 5 of the Athens Metro. It will not open before 2030.
Criticism
Low usage of the station and its unnecessarily large size and the number of platforms have led to the project being criticised as a white elephant.
