Abstract
All critical wheel wear measurements on a static or in-motion train wheel are taken using a non-contact method/system. The train wheel is measured using a modulated point beam of energy impinging the wheel surface from an orthogonal direction, moving the point beam across the wheel surface, and sensing the unique modulated reflection of the wheel using energy sensors that produce analog signals. The analog signals are digitized and processed to produce all critical wheel wear measurements without removing the wheel from the train.
