From Strasbourg you can take a train to any number of destinations in Germany. Just turn up, buy your ticket and jump on. Nobody asks you for your passport. Better still, buy your ticket in advance online and you can get substantial reductions. Germany is rightly proud of its national railway system, which is fast, frequent and affordable. While not all the trains reach such dizzy speeds as the French TGV, they are spacious and comfortable and you may think some second-class carriages are first-class. They have good ideas, like setting aside special carriages for people with babies, where some seats can be raised to make space for a pram, and people who would rather avoid baby noise can sit elsewhere. The stations have mini-escalator strips alongside staircases to take your luggage. And on the train nobody bans you from carrying a bottle of water!
