WILD is a trackside asset protection system that has been specifically designed for applications where wheel impact diagnosis is required to individual wheel level. Defective wheels are a major problem for rail infrastructure operators as they cause serious damage to both rail vehicles and track, and can even be a cause of derailments. The costs associated with replacing track and undertaking vehicle repairs can easily be avoided by installing a wheel impact load detection system. Sensors are mounted directly onto the rails, and each time a train passes, the system records data. A number of wheel defects are detected including pitting, circumferential cracking, out of roundness and wheel flats. Any wheel that generates a force that is above a pre-defined threshold causes alarms to be triggered and a report identifies the particular wheel that needs further investigation.
BENEFITS OF A WHEEL IMPACT LOAD DETECTION (WILD) SYSTEM:
- Provides warning of potential damage to track or rolling stock
- Aids decision making on operational restrictions/remedial action
- All data is quantitative
- Can be extended to provide information of vertical and lateral forces
