Inside a DB 420 S-Bahn at Frankfurt am Main Hauptbahnhof (Tief)

View of the underground platforms at Frankfurt am Main Hauptbahnhof Tiefbahnhof. The outbound platforms can also be seen (Wiesbaden, Niedernhausen (Taunus), Bad Soden, Kronberg, Friedrichsdorf über Oberursel, and Friedberg (Wetterau)). Until the Flughafen Fernbahnhof was constructed, trains were limited to the fully underground Flughafen Regionalbahnhof. Both are in use as of March 2006.
