Perpetuum Rail Solutions

Perpetuum Sensor Systems enable customers to predict failure of rotating components on trains (e.g., wheel bearings, gearboxes, etc.) to:

The Perpetuum product has been deployed on a trial basis on some of our trains over the past year and we have been very impressed by the information it provides us and the ease of use. We foresee a very rapid return on the investment and a solution to unlocking a number of important issues. The system has the potential to redefine the way we undertake some significant and costly elements of fleet maintenance.
– Wayne Jenner, Engineering Director of Southeastern Railways

Southeastern Railways is one of the largest train operators in the UK, with a route mileage of 540 and 179 stations. About 70% of its services run to and from London. See “Monitoring Bearing Health Wirelessly” at Railway Gazette.

  • Improve reliability & safety
  • Dramatically reduce operational and maintenance costs
  • Improve asset utilization – condition is monitored while assets still in service and earning revenue
  • Reduce service disruption

These benefits lead to a rapid payback on investment and a very good business case.

Perpetuum Rail Sensor Systems use key technology to deliver reliable and robust systems that are fast to fit. They are already deployed and operational in the UK passenger rail network.

Key Features

  • Vibration & Temperature Sensors – Early identification of failure
  • Wireless Communication – Avoid cost, time and unreliability of hardwired systems
  • Vibration Energy Harvester – Avoids the cost and unreliability of batteries
  • Robust Design for Harsh Environments – Operate over wide temperature range (-40°C to 85°C), suitable for use in high vibration environments
  • Fast to Fit – Simple deployment
