If you have a thing about trains and transport generally then you might find your inner geek with Berlin Hauptbahnhof. Its like a five level glass cathedral to train travel. I say five levels as ‘five floors” wouldn’t really give the right perspective of how big it is. This is the top level where the S-bahn and long distance trains arrive and leave from. The lowest level is 15m underground and has services such as the U-bahn. In between are a variety of transport options plus the sort of boutique, food and general shops and restaurants you would find in any large modern shopping centre.
