There are no international trains running to/from Greece right now. You could take the train to either Sofia or Skopje, and from there take a bus to Thessaloniki or Athens.

If you can fly for 60 euros, do it.

Hi OlofATW!

Welcome to TT!

I already checked www.bahn.de but I didn't find any relevant information.

As daveelmstrom said in #1, there aren't international trains to/from Greece at the moment. Closer to your travel dates, you could research if they are resumed in any of the possible routes.
In addition, it's too early to look for schedules from mid-June onwards as most, if not all, of them aren't known yet.

I don't think they will be resumed very soon because they stopped running as part of the measurements Greece had to take to stop the recession (as dictated by IMF and EU).

There are no international trains to Greece. But that doesn't mean that you cannot go by train to Northern Greece.
You may for example leave Budapest at 13.00, change at Beograd to the night train and arrive at Sofia at 8.02. Leave Sofia by train at 14.00 and you will arrive at Kulata (Greek border) at 19.28. From there, it's a short taxi ride to Sidirokastro railway station with 2 daily trains to both Thessaloniki and Alexandroupoli.
But it's of course much easier to board a direct Beograd - Thessaloniki bus.

During (part of?) this summer was a seasonal train (only once a week) between Skopje and Thessaloniki. Who knows if it won't be a similar international service* next year? or if the train company of a neighbor country won't extend one of its services to a station on their side of the border to the first station on the Greek side of the border where you could take a Greek train to continue your trip?

*Not necessarily to Skopje as I think this summer's service ended operations earlier than expected due to low occupation...

"I don't think they will be resumed very soon because they stopped running as part of the measurements Greece had to take to stop the recession (as dictated by IMF and EU)"

Neither the IMF nor the EU forced Greece to stop international train traffic. Greece decided alone to stop to produce about 650 train kms per day (from a total of more than 20.000) and to reduce so the revenues from this traffic without reducing the costs (the lines remain open for local traffic and neither the number of engines nor the staff was reduced). It cannot be completely excluded that there could exist more intelligent mesures in order to improve the financial situation of the Greek Republic, for example the taxation of the huge assets of the Orthodox Church or of wealthy shipowners.
