Abstract

In the course of a large, government-financed project Konjunkturprogramm II, infrastructure related innovative measures for the reduction of railway noise and vibrations were installed at numerous hotspots in Germany. The demonstrated effects will be the basis for the formal recognition of these technologies. On behalf of DB Netz (infrastructure), DB Systemtechnik developed a measurement concept and supported the measurement activities.

The results for measures directly at the rail (rail dampers and rail shielding) show effects of up to 3 dB. The application of friction modifiers to reduce curve squeal and rail brake squeal (in the shunting yard) have high effects, both regarding a reduction in maximum noise level as well as occurrence frequency. Low noise barriers may reduce noise by up to 7 dB, but this depends on the height of the barrier, the distance to the noise source and the location of the receiver point. Applied primarily for maintenance of the rail surface, high speed grinding has a very positive side effect on the noise emission. Under-ballast mats and padded under sleeper pads help to tackle vibration problems.
