Development of an On-Board Measurement System for Railway Vehicle Wheel Flange Wear. [PDF]

open access: yesSensors (Basel), 2020
The maintenance of railway systems is critical for their safe operation. However some landscape geographical features force the track line to have sharp curves with small radii. Sharp curves are known to be the main source of wheel flange wear.
