T, if the public transport is anything like Czech Republic then it will be just fine, cheap, on time and comfy!
But just watch out for those occasions when there is engineering works on the railway line. It has happend to me twice when there has been an announcement (which I could not understand) the train stops at the next station and most people get off. You think great loads of room on the train, then 5 mins later a guard comes down to get all the foreigners off and onto a bus!! I think the locals find it amusing....
