Recently,train is running faster and faster,and considering the stability and security,Seamless Welded Rails(SWR) are used as the train orbits gradually. The temperature of the rails will vary with weather.So that the rails may release the energy due to the metal characteristic of expanding or contracting with temperature,there is some badly distortion in the SWR,worsly occurring accidents on expanding orbits.The Portrait Thermal Stress(PTS) of the SWR should be monitored in some parts regularl...
