is it possible to go from Ankara to Tehran by train (OCT 2018) How can I buy the ticket? How many hours for the trip?
No it’s not possible to find a direct train from Ankara to Tehran. It’s still suspended as of November 2017. Closest stations to Iran by rail are Kars (Dogu Express) and Tatvan (Vangölü Express). From there you may try to get to Tabriz by road, and then get on train again.
