I am in the process of planning a Hungary and Romania trip for autumn 2027, and my initial plan was to do the Hungary part solo (5 nights in Budapest with a day trip) and get a customized private tour by Covinnus Travel for the Romania part (1 week), and I would prefer not to fly between Hungary and Romania.
Basically my ideal route for the Romania portion is Sibiu to Bucharest, so I had planned on taking the 09:10 train from Budapest Keleti to Sibiu (Man in Seat 61 mentions this one under Budapest to Brașov, running via Simeria and Sibiu).
Is there generally service all year round for this train? I understand this train can only be booked a few months in advance, but I only see it listed up until Dec 12 on both MAV and CFR. Before agreeing to anything with Covinnus, I want to make sure I'll actually be able to get to Romania from Budapest.
If anyone has any insight on Hungarian train schedules, or perhaps an alternative idea that doesn't involve flying, I would appreciate it.
