Rail Damper Introduction

Rail dampers are the next-generation solutions to railway noise problems. Our rail dampers, invented by our sister company Jabez Innovation Limited, offer 5 unique advantages:

  1. Tunable effective frequency ranging from 40Hz to1600Hz
  2. Corrugation growth suppression up to 90%
  3. Rail noise reduction up to 12dB(A)
  4. Groundborne noise reduction up to 8dB
  5. Rail vibration reduction up to 18dB
