Day 2 (Saturday 19 October) continued:
13.16 Wuppertal Hauptbahnhof to Hannover Hauptbahnhof
15.59 Hannover Hauptbahnhof to Hamburg Hauptbahnhof
I had told Paul all about the train information posters that most German railway stations have. On each platform, a list of every train that will stop there, with a diagram showing how many coaches it will have, and exactly where on the platform you need to stand for your coach. DB can do this, I said confidently, because they are well-organised and it is rare for platforms and train formations to change at short notice.
Then our ICE train to Hannover arrived in a completely different formation to that shown on the poster, and stopped in a completely different position. Oh well.
