Over 90 percent of DB Cargo's freight wagons run on low-noise brake blocks thanks to the introduction of the whisper brake. Since the new brake blocks are made of composite material, they do not roughen the running surfaces of the wheels like conventional cast-iron brake blocks do. As a result, our freight wagons only generate half the usual noise. By the end of 2020, all of DB Cargo's freight wagons in Germany, some 61,000, will be equipped with whisper brakes.
Halving the noise
But not just that. By the end of 2020, Deutsche Bahn will have halved the total level of rail noise. We are not only retrofitting freight wagons to do this. We are also building noise barriers along existing rail lines and fitting residential buildings with sound-insulating windows. In addition, we are developing innovative technologies for vehicles and tracks in order to further reduce rail noise. After all, noise control is also a form of environmental protection – creating a healthy environment for people and animals.
