Since 2010 the 2.2 km long extension of Berlin's subway line U5 from Alexanderplatz to the Brandenburg Gate is being carried out by the municipal transport company Berliner Verkehrsbetriebe (BVG) and its subsidiary Projektrealisierungs GmbH U5 on behalf of the German Federal Government and the State of Berlin. Upon reaching its final position at the Brandenburg Gate on October 14, 2015 the Mixshield “Bärlinde” has successfully completed its tunnelling mission in Berlin. Behind the tunnel boring machine (TBM) are two 1620 m long parallel tubes, built through the historic center of the German capital. In the process a total of 1076 tubbing rings were installed.
