Somewhere between a last coffee on an Athens balcony and the first look at a map of the mainland, the question comes up: is there a train to Thessaloniki? There is.

How does the Athens to Thessaloniki train work?
You buy a ticket from Hellenic Train, the sole operator of passenger services across the Greek railway network, and that one company stands behind every rail journey you make in the country. There is no choice of rival railways to compare, no second brand to learn. That keeps the planning simple: one name, one app, one set of ticket rules.
One company, one network
The Greek railway network has a total length of 1,390 miles, and Hellenic Train is the sole operator of passenger services on it. Most of that network is standard gauge, but the country also keeps a stretch of metre gauge track and a few small gems of a different kind that survive for local and tourist use. The Athens to Thessaloniki trip belongs to the main network.
Having a single operator also means the same app and the same ticketing logic whether you travel between the two cities or head somewhere smaller. If you later add a branch line or a seasonal heritage train to your plans, you stay inside the same system.
Tickets, connections and the Hellenic Train App
Hellenic Train sells what it calls an integrated ticket, which covers the entire journey even when one or more connections are included. In practice, if your route to Thessaloniki is built from more than one train, you hold a single ticket for the whole trip rather than a stack of separate ones. That matters when you are juggling luggage on a platform and want one thing to show.
Plans change on a vacation, and the Hellenic Train App allows for it. With the app you can move your ticket to another date and time by paying or refunding the price difference. If you wake up in Athens and decide the museums deserve one more morning, the switch happens on your phone rather than at a counter.
New trains on the way
Hellenic Train is investing €308 million to bring in 23 new Coradia Stream electric trains. The investment shows where the company is heading: newer electric rolling stock for a network that has spent years being modernized. Whether a given departure uses one of these trains is not something to count on, so treat them as a sign of the direction rather than a promise for your seat.
Electrification is also part of the story further up the line. The Thessaloniki to Alexandroupolis route between Thessaloniki and Drama is planned to be upgraded and electrified up to Serres, with completion set for 2032. That is a project for the future, but it tells you the railway around Thessaloniki is being reworked, not left as it is.
The wider railway you are joining
A ride on this network passes through a country where the rails climb and tunnel through mountains. The Kallidromo Tunnel is the longest railway tunnel in Greece, and the highest point on the whole network is at Kalogeriko. These records belong to the network as a whole, but they hint at the terrain the trains of mainland Greece have to cross, which is part of why people choose the rails over a highway.
The network also includes narrow gauge lines used for local and tourist services. The Diakopto to Kalavryta rack railway remains in operation as a local and tourist service, and the Pelion line from Ano Lechonia to Milies is a seasonal heritage railway. Both run on narrow gauge track, a world away from a mainline journey between the two big cities.
What should you know?
The main thing to know is that the train is one piece of a larger journey, and what you do at each end shapes how the day feels. Hellenic Train runs the service, the ticket can cover connections in one purchase, and the app lets you change the date and time. Beyond those points, the rest is about what you find on arrival and how the railway around Thessaloniki is changing.
Arriving in Thessaloniki: the metro
Thessaloniki has a subway of its own now. The Thessaloniki Metro opened on 30 November 2024, which means a city long used to buses and taxis gained an underground line. For a visitor stepping off a long train ride, that is a new layer of the city to try, and it changes how you can think about getting from a station to a hotel or to the waterfront.
Because the system is new, much of what you read in older guidebooks about getting around the city is out of date. If a book tells you the city has no metro, it was written before that November day. Treat the metro as part of the present-day city and ask locals what stops suit your plans.
Keeping your plans flexible
The app’s change option is the feature travelers will appreciate. A ticket you can shift to another date and time, by paying or refunding the price difference, takes the pressure out of fixed schedules. A late lunch that stretches into the evening in Athens, a festival you decide to stay for, a rainy day that rearranges everything: the ticket can follow you instead of the other way around.
The integrated ticket supports the same spirit. When a journey involves connections, one document covers the whole thing, so you are not reconciling several bookings. Keep the confirmation on your phone, and you have everything the railway asks you to show.
Lines that no longer run, and ones that may come
Not every railway story in Greece is one of growth. The Thrace Suburban Railway service from Alexandroupolis to Xanthi was suspended on 3 February 2010, and it is a reminder that some local lines have gone quiet. If you see a rail route on an old map that does not appear in the current Hellenic Train offer, it may be one of these.
At the same time, parts of the network are due to be rebuilt. The planned upgrade of the Thessaloniki to Drama section, electrified up to Serres, points to a railway that is being rethought around the city. For a traveler in the present, that means the picture of Greek rail keeps shifting, and the safest habit is to look at what Hellenic Train itself offers for your dates.
Small railways worth a detour
If a journey north leaves room for a side trip, the narrow gauge lines make a contrast to the main route. The rack railway from Diakopto to Kalavryta is described as a landmark on rails, and it still carries passengers as a local and tourist service. The Pelion Train runs on a railway with a gauge of 60 centimeters, a heritage line that operates seasonally between Ano Lechonia and Milies.
These are separate trips from the Athens to Thessaloniki run, but they show how much variety the one operator covers.
Good to know before you go
Pay for your trip in euros, and keep the ticket on your phone through the Hellenic Train App so a change of plan costs you a few taps. In stations and on platforms, the usual habits of any busy transport hub apply, and the rest of your trip is yours to enjoy.
