The opening of the two railway stations "Rotes Rathaus" and "Unter den Linden" of the U5 Berlin took place in December 2020. The new railway station "Museumsinsel" is expected to be opened in August 2021.

The project “Gap Closure U5“ from Alexanderplatz to Brandenburger Tor extends the previous U5 underground railway line and merges it with the already completed U55. Apart from 2.2 km of newly built tunnel route also the three new railway stations “Unter den Linden“, “Museumsinsel“ and “Rotes Rathaus“ are established in the centre of Berlin.

In the underground railway station “Rotes Rathaus“ seven centrally arranged columns carry a main part of the floor load. The column heads look like mushrooms with their funnel shape and shall be reminiscent of the old vault of the medieval town hall.

The tunnel section was driven by shield tunnelling method with two single-track tunnel tubes and connects to the existing line at the railway station Brandenburger Tor.
