Rail Noise/Asset Health Monitoring

“By comparing the sound levels generated by different trains, it is possible to identify which trains are generating more noise than others. This information can be used to identify the root causes of the excess noise and to take steps to reduce it.”

Mitigate Problems – Reduce Costs

The noise differences between trains have been shown to be excellent indicators for asset health and maintenance. Dynamic analysis of noise levels close to wheel-rail interface comparing trains in also across the same train can identify targets for inspection and remedy engineering issues before they become a significant problem to reliable service.

This Rail Noise/Asset Health Monitoring has multiple benefits:

  • Autonomous operation for long periods (multi-year)
  • Robust construction to operate in harsh outdoor environments
  • Quick and easy to install
  • Sense when a train is present then sample and analyze noise levels until the train has passed
  • Periodically sample and analyze noise levels when no train is present
  • Report average and standard deviation noise levels
  • Report max X sound levels with time from the start of the train present event
  • Communicate reports to a back-office system

Solution

The Y-WS360 is a robust accurate sensor that can be placed close to the wheel-rail interface. It is easy to install with a magnetic mount.  The self-powered Y-MG105 can be located close to the WS360 (e.g. within 30m) and positioned to have a clear sky for power generation.  For monitoring in dark conditions, a rechargeable battery can support the operation for several months.
