Construction of underground line U5 in Hamburg

An highly advanced underground line, running automatically with green electricity is being built. With a route length of 24 kilometres and 23 new stops, it will connect districts in the east and west of Hamburg with the city centre. On the occasion of this event we congratulate all teams involved on this project. A joyful and proud look falls on the groundbreaking ceremony. Since 2016, our experts in tunnel construction have been encharged with the planning of the first realisation section of the project. Over the years, a long and successful cooperation has developed with Hamburger Hochbahn AG and the project partners. With the groundbreaking ceremony, another important milestone will be reached together.

The aim of this project is to build what is currently Germany's most climate-friendly underground railway. Planned as a completely emission-free means of transport with 100 per cent green electricity, Line 5 will be for the expected 270,000 passengers an environmentally friendly alternative to private cars.
