Surprised to see no mention here of the DB strike. Our train from Prague to Berlin dumped us in Dresden on Wednesday and then DB bussed us to Berlin. We can't get to Cologne via DB tomorrow (we were to have taken trains from Cologne to CDG on Tuesday) and so we just bought plane tickets to get us to Paris so that we are sure to be there for our trip home.
Anyone arriving in Germany through at least Monday afternoon which is when they think the strike could be over is going to have to scramble if train travel is part of your itinerary. DB has announced that they can accommodate only 30% of their train travelers on buses.
