According to Bulgarian train website currently the schedule is set till 10.12. We are planning to take the train on the 23 at night and now are wondering if trains are still going in winter? Any one know about the winter schedule of the trains?
Also, is it possible that Nighttrains from Buccharest to Vienna can only be booked one months in advance? I noticed that after that tickets are available till the 8th of december, but are not available after.
