Graz, Austria

The Hengsberg Tunnel is part of the Koralmbahn, the largest project currently under construction for the expansion of the Austrian railway network, which will connect the central areas of Graz and Klagenfurt directly. In the summer of 2016, median absorber plates and solid concrete edge elements were produced and assembled for the 3 km long Hengsberg tunnel in Styria Rieton. This special noise control is placed between the railroad tracks and offers a good solution for noise reduction especially in the tunnel, where the noise is reflected by the walls.
