Hi all
I would like to take the train from Athens to Thessaloniki on August 16th, but the Interrail app indicates a compulsory seat reservation. I cannot do this via the Interrail website (Not available from Interrail.eu. This seat reservation can’t be booked on our website. Check 'More information' for other ways to book.), but I can’t seem to find a way to reserve a seat via the Hellenic Trains or Happyrail websites either.
Does anyone know how to do this? I will be in Athens from August 8th on - would it be an option to make a reservation at the train station in person? Thanks in advance!
