A train speeds through the country on its way to Berlin, then gradually slows down as it pulls into the station. It is very early in the morning, about 5:00 AM, and the great city is mostly quiet. But before long there are some signs of activity, and a few early risers are to be seen on the streets. Soon the new day is well underway - it's just a typical day in Berlin, but a day full of life and energy.
