Freight wagon noise: railway is testing smaller noise protection walls

Passing freight transport disturbs residents in many regions of Germany. Huge protective walls to block noise. Now Deutsche Bahn is testing smaller walls, but should be just as effective.

Deutsche Bahn is testing new techniques for the protection of freight wagon noise. "For example, the low noise protection walls and so-called Mini-sound-protection walls, which are built directly on the tracks," said the DB-noise protection officer, Andreas Gehlhaar, the German press Agency. Thus, the meter-high gray Aluschallschutzwände in residential areas would not be in the future, maybe needed everywhere.

bridge rail dampers are to be tested. Currently being tested in a federally funded and ongoing project about 30 techniques for noise reduction, as it was called from the train.
