The work required the removal and disposal of the old elements and the preparation of the ground for the new paving and laying work at each of the stops. The work was carried out exclusively in night shifts in order to allow services to continue to run without interruption as far as possible; a total of around 2,000 metres of new guide elements was installed!
The project was concluded with the underground station at Willy-Brandt-Platz where the final work was completed at the end of March.
