Summary Steel bridges without ballast are very often sources of annoying railway noise. While the insertion of a trough filled with ballast will lead to a noise reduction of about 6 dB(A), it causes an increase of the static mass of the bridge construction of about 30%, which then requires additional measures of reinforcement. In this paper 4 different systems of noise mitigation are presented, which are based on decoupling and damping effects. A noise reduction of 4.5 dB(A) to 10 dB(A) was achieved with an additional mass of less than 15% of the weight of the bridge and therefore no reinforcement was needed.
