Abstract—The propagation time of longitudinal, transverse, and transformed ultrasonic waves in three R65 rail segments is estimated as a function of temperature using a high-speed acoustoelasticity-based microprocessor system. The obtained time dependences and the results of estimating the errors of measuring the time parameters made it possible to calculate the longitudinal stresses over the entire sonic test rail volume in an operating railway track segment at an error of at most 10%.
