Wheel Impact Load Detector (WILD)

Impact load occurs on rail when a defective portion of wheel falls on rail head. Impact load is transferred to rail head from wheel through combination of any or all of the following defects like

  • Wheel having a flat / Out of roundness
  • Overloaded Axles
  • Defect in suspension system
  • Miss-alignment of bogies
  • Skew in the car body etc

WILD

Wheel Impact Load Detector (WILD) is a Safety System used to identify the defective wheel due to any of the above defects by measuring the dynamic impact on the track at a very early stage and thereby protect the Rail Infrastructure, avoid derailments and catastrophic failures. WILD is also to reduce service failures and unplanned maintenance cost of Rolling Stocks and Tracks.

WILD System was initially developed along with RDSO & IIT-Kanpur
