You can issue or re-charge Smart OASA tickets exclusively at Hellenic Train ticket offices, as well as at OASA automatic ticket machines located in selected stations across the network.
These electronic fare media are interoperable, allowing you to travel on all OASA transport modes, as well as on Hellenic Train services within the urban section of Attica: from Piraeus to SKA / Koropi / Magoula, and up to the Athen Airport Station.
Holders of reduced, rechargeable, interoperable electronic tickets may travel on Hellenic Train services provided they meet the eligibility criteria for discounts as defined by the Hellenic Train Discount Policy, and upon presenting the required documentation both at the time of issue and during ticket inspection onboard.
