Looking to travel from Istanbul to London by train, but having some difficulties with planning. Can someone confirm if the Bosporus Express is definitely running? Also, how does this train work with an Interrail Pass, given that you can’t book in advance online, and can only secure tickets at the ticket office in Hakalli Station. Do you just show the pass at the office, and do you have to pay any extra money? Also, how likely is it that there will be spare places onboard, given that we will only be able to arrive at the station just before the journey.
It’s my first time getting an Interrail Pass, and so not quite sure how the system works.
