After a construction period of around ten years, trains are running on the new section of the U5 metro line between Alexanderplatz and Brandenburg Gate.
People walk through the underground station Unter den Linden. Ten years after the ground-breaking ceremony, a new underground section in the centre of Berlin went into operation.
The information board at the Brandenburg Gate shows the new stations on the extension of the U5 underground line between Alexanderplatz and Brandenburg Gate.
