In the interest of local residents and the environment, Deutsche Bahn has set itself the goal of significantly and permanently reducing train noise by 2020. A universal effect is achieved by reducing noise directly on wagons. With the incentives from the NDTAC, DB Netz AG is therefore promoting the upgrading of existing freight wagons to low-noise brake technologies.
After 8 years, the NDTAC expired on December 12, 2020. The railway noise mitigation act has been implemented as a follow-up to NDTAC since December 13, 2020.
