Vienna subway tunnels for U2/U5 line finalized

Vienna's subway expansion project has reached a significant milestone with the completion of tunnel excavation for the first section of the U2/U5 line. The tunnel boring machine, affectionately named "Debohra," has finished its work, paving the way for the next phase of construction.

Debohra, an impressive machine with a seven-meter diameter cutting wheel, has been working 35 meters beneath the surface in the Neubau district since September 2024. It was responsible for excavating the tunnel tubes that will eventually carry the extended U2 line from Rathaus station towards Matzleinsdorfer Platz. The machine bears the marks of its arduous journey, showcasing the challenges of underground construction.

With the tunneling phase now complete, the focus shifts to the interior finishing and technical installations required for the five new stations. These stations are slated to open to the public in 2030, marking a substantial upgrade to Vienna's public transportation network. The project aims to improve connectivity and efficiency for commuters in the Austrian capital.
