The Acharnes Railway Center (Greek: Σιδηροδρομικό Κέντρο Αχαρνών) or SKA is a two-level railway station in the northern parts of the Athens agglomeration, in the suburb of Acharnes, where several important railway lines converge. It is an important passenger interchange station linking The main Piraeus–Platy railway line from Athens Central to Thessaloniki and the Athens Airport–Patras railway. The station opened in April 2011.
The railway from Piraeus to Platy is an electrified double-track railway line that connects Athens to northern Greece and the rest of Europe. It constitutes the longest section of the mostly completed higher-speed rail line known as P.A.Th.E./P., which includes Greece's most important rail connection, that between Athens and Thessaloniki. Its northern end is the station of Platy, on the Thessaloniki–Bitola railway. In the south, it connects to the Athens Airport–Patras railway at the Acharnes Railway Center. The line passes through Thebes, Katerini and Larissa, and offers connections to several other cities (Chalcis, Lamia, Volos, Karditsa, Trikala) through branch lines.
