As beggining of this topic, I'd like to answer about this picture I've seen in Facebook, posted by Γιώργος Δάγλας in the 'Trains in Greece' group.
Named as 'Golden Eagle. Danube Express', those coaches appeared in your tracks.
As seen in the http://www.goldeneagleluxurytrains.com/ lost of exciting trips are on tracks, and some are involved in balkan routes
I think it's a good idea to look for more pictures of this train
