Abstract
A system for measuring wheel wear of a railroad vehicle includes a first speed measuring device, such as a microwave doppler speed sensor for measuring speed of the vehicle independent of wheel rotation rate, a second speed measuring device for measuring vehicle speed in terms of wheel rotation rate and a comparison device for measuring the difference of the two speed signals over time to therefore provide a signal indicative of wheel wear.
