AT A GLANCE

In the Ammer valley, the Tübingen-Herrenberg railway line was reactivated as early as 1999. Since this line runs through residential areas the railway operator was looking for a sound protection solution that would be as effective and inconspicuous as possible at the same time.

Due to its low height, the mSW 360 from STRAILastic proved to be the optimal solution here. The mini sound protection wall is installed just outside the standard clearance area.

On the railway line in the Ammer valley, there were different types of sleepers such as wooden sleepers and short concrete sleepers as well as large tolerance deviations in sleeper spacing. However, these requirements posed no obstacle to the installation of the mSW 360.

The mini sound protection wall is attached to the metal substructure with just a few screws, which in turn is fixed directly to the rail. To compensate for the large tolerance deviations in sleeper spacing, special rubber bellows were developed by STRAIL and successfully used by the construction workers. Furthermore, there is the possibility of integrating small animal passages.

The installation of the mini sound protection wall proceeded quickly. The railway operator and the residents are very satisfied with the STRAILastic solution, as the residential area is now quiet and the local landscape is not disturbed.
