Operator missing STASY — Metro Lines 1–3 + Tram (via data.gov.gr) is named on this page but contributed nothing to these numbers — that schedule ended August 31, 2026. The grade and the map below describe the rest of the network only, so read them as a floor rather than a picture of the whole city.

Part of the network This covers STASY's Metro Lines 1, 2, and 3, the Athens Tram, and OSY's city buses and trolleybuses — the network OASA publishes a combined schedule for. The Proastiakos suburban railway (Hellenic Train), which also reaches the airport alongside Metro Line 3, isn't included: Hellenic Train publishes no open timetable data for riders to draw from.
