That's why I love travelling in Eastern Europe and on this route as well !!!
It is always adventure, you meet nice people (travel companions and beer bringing conductors) and I am sure, you will always have this trip in your mind even in 10 years.
Like you said, it is not Germany - but it would be boring if everywhere in the world it is the same standard, everything in time (German trains also love delays). Enjoy it, relax and always have some beer with you.
