When Berlin's public transportation system got revamped in the early 2000's this station became one of the central hubs for the Northern part of Berlin.
For the city train, you'll be able to transfer along the North-South lines and onto the Ring (circle train).
Subway connection is to the U6 which will bring you to Mitte / Kreuzberg (South) and Wedding (North).
There are also regional trains that either end/start here or making their way South through Potsdamer Platz and/or Hauptbahnhof.
Located next door is the Gesundbrunnen Center, a big shopping mall, as well as a Holiday Inn.
Not the best area in general so make sure to just transfer. read more
