re: European Train Transfer Times

Euro trains run on time so the transfer times you gave should be ok unless you have little kids with you and you haven't checked any bags. I have been on trains where they require you to check bags larger than a small carry-on so you may want to check this before hand. That's not to say you don't need to hustle a little. I think a transfer time of less than 10 minutes at a big station would be pushing it.
