Hello, I’m planning an Interrail trip and want to travel to Istanbul from Bucharest. There’s a night train that goes via Sofia called the Sofya Express. The Turkish transport website states that it can be used with an Interrail pass. However, I can’t find this route on the Interrail app. Has anyone else taken this train before?

 

Thanks in advance for your replies and help!!

You have to add the journey manually. As its missing from the timetable interrail uses.

Yes, the pass is valid. But note that you can’t buy reservations online. You can buy them at the station in Bulgaria, or through an agent such as Discover by Rail. Details here: https://www.seat61.com/interrail-and-eurail-reservations.htm#Bulgaria

You can buy regular tickets online, on the TCCD website, at least for the overnight section, so it’s worth thinking if you want to use a travel day and attempt to buy a reservation, or just buy a regular ticket online for a lot less hassle.
