Dynamic behaviour of current collector shoes

Improve safety and reduce track maintenance costs through better understanding of the damage suffered by current collector shoes.


  • Check the quality of the “current collector shoe-rail” interface
  • Detect and locate possible impact and vertical deflection of current collector shoes that can lead to their deterioration or premature wear
  • Pinpoint the place and the nature of the impact on the network, and display it in order to quickly implement corrective action
