Germany: Deutsche Bahn Project - Albabstiegtunnel Stuttgart - Ulm


  • The around 60 km long new Wendlingen-Ulm line is a sub-project of the Stuttgart-Ulm rail project and enables a quick and comfortable route across the Swabian Alb.
  • The railway tunnel "Albabstiegstunnel" is almost 6 km long and connects the southern German Alb plateau with the main train station Ulm. The new infrastructure allows maximum speeds of 250 km/h.
  • ERHARD delivered high pressure valves for the separation of the extinguishing water pipe segments in the traffic tubes, designed for 40 bar.
