Entering the Real Operation Phase: Design, Construction and Benefit Verification of Freight Wheel Noise Absorber

Until today, freight train noise is the main annoying railway noise in many places around the world. Numerous approaches were started in the past to establish mitigation measures. An integrated system of a silent wheel design with additional vibration absorbers has been established. Different tests have proven the noise level LAeq,Tp (according ISO 3095) is reduced by about 4 dB. Also, the homologation according TSI Wagon was confirmed, enabling a European wide operation. Practical barriers for the implementation are now the missing motivation for freight wagon owners to improve their fleets’ noise below TSI Noise limits. This paper introduces technical data and background as well as thoughts on the implementation and current system constraints.
