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.

The existing train station of Patras will get a new function in a new recreational space.

[16] 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.

A tender note has been published by ERGOSE SA, with Jan 14th 2022 deadline.
