Keller Group - Partial Renewal of the Rauheberg Tunnel

The Rauheberg Tunnel with a length of 5.21 km is located on the DB high-speed rail line between Hanover and Würzburg, one of the most important connections in the German railway network. Keller Grundbau carried out successful stabilization and grouting works around the clock (24/7) to partially renew the tunnel, enabling trains to once again travel at high speed on this route.
