# Athens Airport–Patras railway

The railway from Athens Airport to Patras is a double-track, standard-gauge railway line in Greece that, when completed, will connect Athens International Airport with Patras, the country's third-largest city. One of the largest railway projects of the last 30 years in Greece, its completion is of major significance for the infrastructure of the entire region of the northern Peloponnese. As of 2020, the line is completed until the city of Aigio. A 5.2 km underground section is planned for the final section from Kastellokampos to Agios Andreas in Patras. For most of the section between Athens Airport in East Attica and Mandra in West Attica, the line runs along the median strip of the Attiki Odos motorway.

* Line 1: Piraeus–Athens–Airport (also uses the Athens-Thessaloniki Railway)

## Future

As part of the P.A.Th.E./P. project, the line is being extended to Patras. The remaining part from Rio to Patras will be partly underground with a terminus in the new harbour. The existing train station of Patras will get a new function in a new recreational space. The electrification of the Kiato–Aigio section will allow direct services to and from Athens, as passengers must currently change between electric and diesel trains at Kiato. On the south-eastern side, the line will be prolonged up to Lavrio and Rafina. A tender note has been published by ERGOSE SA, with Jan 14th 2022 deadline.
