about rail longitudinal stress measurement

Hi everyone,
Rail will produce great thermal stress when enviroment temperature change greatly.Without taking appropriate measurement rail would be broken or bulged,and threats the safty.Do you know how to measure the thermal stress in rail? I would be glad if you give me some inforamtion about the measurement of rail thermal stress.
thank you very much!
Best regards

Re: about rail longitudinal stress measurement Hallo!
Ask at the Fraunhofer Institut for NDT, (www.izfp.fhg.de) in Germany. They had an Ultrasonoscope (UES) for the determination of the tensile state of new rails and of rails in the track.
Best regards.
