🚆 What the Proastiakós is
The Proastiakós (Προαστιακός — literally "suburban") is the Athens regional rail network operated by Hellenic Train (formerly TrainOSE), serving the broader Attica region with longer-distance commuter trains. Unlike the metro, it uses standard-gauge rail and is part of the national OSE rail network.
For visitors, only one branch matters: the airport line to Larissis Station via Acharnai (SKA junction). It runs alongside metro Line 3 for part of the route but with very different stopping patterns and destinations.
📍 The route
Airport (start)
Same station as metro Line 3 — go to platform 3 or 4 (signed "Proastiakos / Suburban Rail") rather than platforms 1/2 (metro).
SKA / Acharnai
The major junction in northern Athens; transfers possible to other Proastiakós lines (Halkida, Patras, Kiato).
Athens (Larissis Station)
The terminus for visitors. Larissis Railway Station is the main intercity station for Athens, with metro Line 2 connection (red line, "Larissa Stathmos" stop) for onward travel into the centre. ~6-minute walk from Victoria Square / Pedion Areos park.
💶 Fare
The fare is €10 single (the same combined airport-area surcharge as metro). The airport-Larissis Proastiakós is part of the OASA-integrated airport ticket — a 90-min OASA airport ticket allows free transfer to OASA metro/buses on arrival. Tickets are sold at the airport platform vending machines, OASA kiosks at the airport, or via the OASA app. (See tickets and passes guide.)
⏱️ Travel time and frequency
~38 min airport → Larissis
Direct, with limited stops at SKA and a few intermediate junctions. Comparable to metro Line 3.
Every 25–40 min
Frequency varies by hour and day; less frequent than metro Line 3 (which runs every 10-15 min).
~05:30 to ~22:30
Operating hours — earlier first train and earlier last train than the metro. Always check the OASA / Hellenic Train timetable before travelling.
+9 min metro to Syntagma
From Larissis you transfer to metro Line 2 (1 stop to Omonoia, 2 to Panepistimio, 3 to Syntagma).
🎯 When the Proastiakós is the best choice
- Staying in Victoria / Pedion Areos / Larissis area. The Proastiakós drops you a 6-10 minute walk from these neighbourhoods, vs metro Line 3's slower indirect route.
- Travelling onward to other Greek cities the same day. Larissis is the main intercity rail station. Combine airport arrival → Proastiakós → Hellenic Train onward to Thessaloniki / Patras / Kalambaka without leaving the rail network.
- You prefer trains to metros. Proastiakós trains have larger seats, more luggage space, and inter-city quality interiors. A genuinely more comfortable ride.
- Crowded metros. If metro Line 3 is rammed (rush hour, summer Saturday), Proastiakós is usually quieter.
- Avoiding the Monastiraki interchange. If you're going to Larissis area or beyond by intercity train, Proastiakós cuts out the Syntagma → Omonoia → Larissis transfer.
🚫 When NOT to use it
Skip the Proastiakós if you're going to...
- Plaka / Acropolis area. Metro Line 3 takes you direct to Syntagma or Monastiraki — fewer changes than Proastiakós + Line 2 + walk.
- Piraeus / port. Metro Line 3 is direct from airport to Piraeus (post-2022 extension). Proastiakós would require multiple changes.
- Anywhere on metro Line 1 (green). Multiple transfers needed via Proastiakós; metro Line 3 + change at Monastiraki is simpler.
- You're arriving at peak hours and need predictable timing. Metro frequency is more reliable.
- Late-night arrivals. Last Proastiakós ~22:30 vs last metro 23:30. Don't bank on Proastiakós at night.
🏛️ Connections at Larissis Station
- Metro Line 2 (red) — "Larissa Stathmos" station, integrated walkway. 1 stop to Omonoia, 3 to Syntagma.
- Hellenic Train intercity — same building. Direct connections to Thessaloniki (~4 hrs), Patras (~3 hrs via Korinth), Kalambaka/Meteora (~5 hrs).
- OASA buses — multiple routes terminating or passing Larissis Station.
- Taxi rank — outside the main entrance. €5-€10 to most central destinations.
- Walk to Victoria Square — 6-8 minutes through Pedion Areos park. Walk is straightforward but Pedion Areos has a thin reputation at night; daytime is fine.
🧳 Luggage and accessibility
Proastiakós trains have luggage racks and larger doors than metro carriages. Stations are step-free with lifts at airport and Larissis. Wheelchair users can travel on Proastiakós; staff at Larissis can assist if requested in advance.
🎟️ Ticketing in detail
The €10 airport-area combined ticket is the standard option. Other variants:
- 3-day tourist ticket (€20) — includes airport segments + unlimited city travel for 3 calendar days. Worth it if you'll do the airport round trip plus 3 days of central Athens travel.
- Athena Card (top-up) — load €20 onto the card, valid for multiple airport trips. Cheaper if you have multiple airport runs (e.g., transit + return).
- Children under 6 free; ages 6-18 reduced fare with documentation.
Validate at the platform validators before boarding. Inspectors do check Proastiakós; €72 fine for unvalidated.
📅 Onward travel from Larissis
If your Athens visit ends with a train onward (Meteora, Thessaloniki, Patras), arriving by Proastiakós at Larissis means you don't even leave the rail network. A typical itinerary: Land at airport 14:00 → Proastiakós to Larissis 14:50 → Hellenic Train to Kalambaka (Meteora) 15:30 → arrive Meteora 20:30. The two trains share the same station — no bus, no taxi, no metro.
⚠️ Practical caveats
- Strikes affect Hellenic Train and Proastiakós equally. Greek rail strikes happen 4-8 days/year. Always check the morning of travel. (See strikes survival guide.)
- The connection at Larissis to metro Line 2 is well-signed but indoor walking is ~4 minutes. Add this to your transit calculation.
- Limited late-night service. Last train at ~22:30 means a late flight is metro or taxi territory.
- Schedule changes. Hellenic Train timetables update twice a year; the OASA app sometimes lags by a few days.
🎯 FAQ
Is the Proastiakós faster than the metro?
About the same time to Larissis (38 min Proastiakós vs 38 min metro to Larissa Stathmos). The metro then continues to Syntagma directly; Proastiakós requires a metro Line 2 transfer. So metro is faster to most central destinations.
Where exactly do I find the Proastiakós at the airport?
Same building as the metro. Follow signs for "Suburban Rail / Proastiakos." The platforms are 3-4 (vs metro 1-2). The ticketing is shared with metro but the platforms are physically separate.
Can I use the metro day-pass on Proastiakós?
OASA day passes are valid on Proastiakós within the urban zone (including Larissis). For airport segments, you need an airport-zone ticket regardless.
Is the train more comfortable?
Yes — Hellenic Train Proastiakós trains are inter-city quality, with larger seats, more legroom, luggage areas, and air conditioning. The metro is a city subway by comparison.
Are there reservations?
No — Proastiakós is open seating, like a metro. Hellenic Train intercity trains do require reservations.
