I love living next to a metro station. It really makes life so much easier when you know that getting somewhere, or coming back home from somewhere, is just a metro station away from your home. I only need to walk 10 minutes and I am at the metro station. But it is not just any ordinary metro station. This one is located in Berlin's main train station, Berlin Hauptbahnhof. Berlin's central train station is quite the building- it took 8 years to complete its construction (and I thought that Germans were efficient!!!!), but when you consider that it is Europe's largest two-level railway station, 8 years does not seem to be that much time. There is traffic on five levels- that means that more than 1,800 trains call at the station every day and the daily number of passengers is estimated to be at 350,000- now that's worth it!
