Together with our partner ANGERMEIER INGENIEURE GmbH, we are implementing the framework contract for digital recording, data processing and defect analysis of the tunnel infrastructure of DB Netz AG. Over the next four years, this will enable infrastructure operators to scan the tunnels of the entire DB rail network uniformly using our latest technology (a total of around 740 tunnels with a total length of approximately 600 km). The goal is to capture and evaluate all tunnel structures in their entirety. Using our expertise in 3D scanning of tunnels, we will capture high-resolution images and create a true-color 3D model that provides numerous details for evaluating the structural condition of all tunnels.
Among others, the Petersberg Tunnel has already been scanned, for which we were able to create high-resolution results and defect images. Built in 1874 and recently rehabilitated, the tunnel stretches over 350 meters along the Mosel line between Neef and Edinger-Eller in Rhineland-Palatinate in Germany. The double-track tunnel passes under the Petersberg mountain and is named after it.
Completed in 1988, the Schwarzenfelstunnel stretches over 2.1 kilometers in the Hessian municipality of Sinntal. The double-track tunnel is driven by railroads at 250 km/h. Pretty fast, as you can see in the picture. As part of the framework contract, our scope of services was the surveying of the tunnel. We digitally recorded the building and processed the resulting data into a true-color, high-resolution 3D model. These results can be used to create damage analyses.
