When my commuter train arrived at the station I wanted to change on last night, I saw the other train waiting at the other platform. I was in the first carriage and everything was empty, so nothing and no-one blocked me. I ran out and down the stairs and up to the other platform only to see the train leave right at that moment. The next one was to arrive 25 minutes later because of construction work. It was below freezing (yes, below freezing) and apparently, nobody saw the need to delay the train by one minute to ensure at least one person could manage to change. Something tells me this would only happen in Berlin.
