The station is served by the Athens Suburban Railway towards Piraeus and Hellenic Train local services to Aigio.

In 2009, with the Greek debt crisis unfolding OSE's Management was forced to reduce services across the network.

Initially, Kiato railway station served as an exchange point for passengers to Patras on the old metre-gauge line from Piraeus, but all regional services on the metre-gauge lines of the Peloponnese were suspended indefinitely in December 2010[8] for cost reasons.

Since 15 May 2022, this station serves the following routes: Pending the electrification of the Kiato–Aigio section, passengers must change between electric and diesel trains at Kiato.

Pending the completion of the Athens Airport–Patras railway, passengers travelling to and from Patras may use Hellenic Train's rail replacement bus services (ten per-day, as of 2025), which connect the city with Kiato, Diakopto and Aigio stations.
