Development of acoustically optimized rail pads

 

Customer: Swiss Federal Office for the Environment (BAFU), Switzerland

Customer benefit

  • PROSE is operating in the field of vehicle design and testing and knows the systematic relationships of track dynamics and acoustics
  • In this project, it focused on the as-built analysis, simulation models, laboratory tests and installation and measurements on test tracks
  • BATEGU is a developer of rubber compounds and manufacturer of damping elements for use in rail vehicles
  • It contributed the know-how for the development of a suitable material and the design of the rail pad

Project tasks

  • Swiss rail traffic shall become quieter - therefore, the BAFUand BAV encourage noise and vibration reducing measures in railroad construction
  • For this, PROSE went to the source of the noise directly together with the rubber manufacturer BATEGU
  • We then developed a new rail pad that reduces rail noise by up to 4 dB (A) and at the same time protects the railway superstructure
