An ultrasonic probe has been designed, evaluated and shown capable of measuring longitudinal stress changes in railroad rails. The probe uses the effect of applied stress on wave velocity (acoustoelastic effect) to determine the stress change. Both laboratory and field evaluation has shown that the probe is capable of measuring stress changes with an accuracy of plus or minus 6.9 MN/sq m (plus or minus 1 ksi).
