There is no security check-through on international trains. No X-rays, no wandings, nothing. This is because of the EU, which, due to its “open boundaries” policy, makes such precaution illegal.
Also, so far I haven’t seen any fountain drinks anywhere. Unless you count beer on draught. Just cans and bottles. And don’t think you can get a bottle of Welch’s Grape, either. The closest juice-like concoction I’ve found is Orange Fanta.
