Hiya,
Found this in a quick search;
By Train
Rail services link Thessaloniki with, Athens and the towns of Macedonia and Thrace. The line through Yugoslavia provides connections with Central and Western Europe when there is not a war. The line through Bulgaria connects to Eastern Europe and the line through Istanbul, Turkey with the countries of the Near East. Information: State Rail ways office at No 18, Aristotelous St. tel.2310 276.382 and the new railway terminal, tel. 2310 517.517.
Or visit www.athensguide.com/practicalinfo where you can find more information on the troubled National Train System of Greece. They have just received a large EU Grant for improving train service on the Athens-Thessaloniki line, among others. Be aware that there are express and local trains and the locals make a million stops and take hours longer to get between Athens and Thessaloniki.
According to the schedule I have there are trains from Athens to Thessaloniki at:
6:50(IC), 7:50(ICE), 9:54, 10:50(IC), 13:23(IC), 14:50, 16:24, 19:22(ICE), 20:40(IC), 22:57 and 23:55.
Costs
The slow trains cost 15 euros and take 6 hours and the fast trains(ICE) cost 50 euros and take 4 hours and 20 minutes. There is something in between(IC) that takes 5 hours and costs 36 euro.
Hope that helps out a bit.
