It opened on 9 July 2007 as the western terminus of the new standard-gauge line from Athens Airport. In 2009, with the Greek debt crisis unfolding OSE's Management was forced to reduce services across the network. Timetables were cutback and routes closed, as the government-run entity attempted to reduce overheads. 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 for cost reasons. The old Kiato–Sikyona railway station [el] nearby was also closed. In 2017 OSE's passenger transport sector was privatised as TrainOSE, currently a wholly-owned subsidiary of Ferrovie dello Stato Italiane infrastructure, including stations, remained under the control of OSE. In July 2022, the station began being served by Hellenic Train, the rebranded TranOSE.

The raised station is assessed via stairs or a ramp. It has one side platform and one island platform, with station buildings located on platform 1, with access to the platform level via stairs or lifts. The Station buildings are equipped with a booking office (not yet operational) and toilets. At platform level, there are sheltered seating, an air-conditioned indoor passenger shelter (as of 2020 not open) and Dot-matrix display departure and arrival screens and timetable poster boards on both platforms. There is a large car park on-site, adjacent to the eastbound line. Currently, there is no local bus stop connecting the station.

Since 15 May 2022, this station serves the following routes:

• Athens Suburban Railway Line A4 towards Piraeus, with up to one train per hour;
• Hellenic Train local service towards Aigio, with six trains per day, from 07:00 to 20:00.

Pending the electrification of the Kiato–Aigio section, passengers must change between electric and diesel trains at Kiato. Those travelling to and from the airport may also take lines 1 and 2, changing trains at Kato Acharnai. Pending the completion of the Athens Airport–Patras railway, passengers travelling to and from Patras may use the TrainOSE bus lines which connect the city with Kiato, Diakopto and Aigio stations. Diakopto is also the terminus of the unique rack railway to Kalavryta.

• At Kiato station, the works in the first track of the station are about to begin. The project has consisted of various steps, and the final goal is the downgrade of the track, as in 2007, it was higher than the others so that the meter gauge trains could fit onto the platform. Now, as they're no more meter gauge trains there and the new line to Diakopto has almost been completed, the station must be ready. The works will start with the removal of the ballast and the track in order to dig the ground for the downgrading. The K2 is the ballast cleaner of Hellenic Railways and is the oldest maintenance rail machine that is still in use in the country. It was transferred on Sunday, 25 September, from A.I.Rentis depot to Kiato station, via Athens and the new line, hauled by MLW MX627 A 456 and A 458. This is a rare transfer not only because of the ballast cleaner but also for these MX627 locomotives that entered the line to Kiato.
