From Istanbul to Thessaloniki by train

The Question:

Thanks very much, Stavros. I think I will take the ferry from Volos.
If you have time to answer another question, I'd really appreciate it: Do you know about the trains from Istanbul to Thessaloniki? I know there is a night sleeper train, but I'm travelling alone, and apparently the price for a sleeping compartment is around 85 euros for one person. I've read on the internet that there is a day train as well, but I can't find any official information on it. Do you know if it actually exists?
Thanks alot. Every country should have a blogger like you to make things easier for travellers. It's a great service.

The Answer:

Hey Joe and thank you for all your kind words!
Regarding the day train from Istanbul to Thessaloniki, as far as I know it departs at 08.30 a.m. and arrives in Thessaloniki at 23.50. It makes several stops and the first class tickets cost 50euros. This train line used to be IC91. But since the train schedules change constantly, ti would be better to call the greek central train station to confirm this itinerary. The phone number is 0030 210 5240601.
Hope this has helped...
