I will be traveling to Hungary next month and **I would like to know if the trains and buses between different cities are punctual or not**. I am from Spain and here, in general, the trains are but the buses are not (due to traffic jams and similar stuff).

I've found [this survey](http://ec.europa.eu/public_opinion/flash/fl_326_en.pdf) but it doesn't give me any information about buses (which I expect to be less punctual than trains) and the information about trains is also not very clear to me.

I will note that I still consider it to be punctual if it just involves a difference of a few minutes (up to fifteen minutes more or less) with respect to the established schedule. I'm just concerned with major delays.
