Construction phase 6
The U55 Shuttle Line from Hauptbahnhof to the Brandenburg Gate
Work on the second entry, which is required for fire protection reasons, can only start when the station shell is completely finished.
The second entry will be installed in the initial shaft to the east.
For further extension work on the U5 line linking Alexanderplatz to the Brandenburg Gate, subterranean shield driving machines can be docked directly onto this tunnel, which means that no additional deep tunnel work will be necessary at this site
