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 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.
