The eRDM240 is a dynamic wheel load diagnostic system (WILD) for the measurement of wheel load, axle load, wagon load, and the detection of wheel defects at travelling speed. evopro Innovation was awarded the Hungarian Product Prize in 2014 and the Innovation Grand Prize in 2015 for the development of eRDM system.


  • Measurement of wheel load, axle load, and wagon load
  • Detection of overloading and asymmetric loading conditions
  • Detection of wheel flats and bogie problems
  • Transmission of automatic alarm signals for operating stations


  • Increase the safety of railway traffic
  • Verification of rated axle loading on track
  • Comparison of measured and declared payload
  • Detection and signalling vehicle problems
  • Increase the utilisation and availability of infrastructure
  • Support condition monitoring and predictive maintenance of railway vehicle
