This is really helpful info. When I went on a train to get back to Cologne from Angie's house, I got on the train and nobody was on it! I was on the train for 30 minutes before someone else got on and it left about 1 hour after scheduled! I had no money and no phone it was so scary I had to ask someone for their phone in German and explain my situation. Just goes to show that not everyone knows English and you should not travel to a foreign country without knowing some of their native language!
