| The temperature stress in the rail is: e * ¡÷ L / L = e * a * ¡÷ te is the elastic modulus of the rail, e = 210000 mpaea is the change rate of the rail stress to temperature. The temperature stress of the long rail of CWR has nothing to do with the length of the rail, only related to the rail temperature change. Therefore, theoretically, the jointless track can be infinitely long. The temperature change of the rail section is ¡÷ TF = 2 t. The temperature force inside the rail keeps balance with the longitudinal resistance of the track at any time, which is the basic basis for analyzing the distribution of the temperature force inside the rail. Turnout: in the railway line, the track connection equipment that makes the locomotive and rolling stock turn from one line to another is called turnout. The turnout is divided into ordinary single turnout, single symmetrical turnout, three turnout, intersection line and intersection turnout. The turnout is connected by the switch and frog and the turnout sleeper. There is no rail bottom slope on the ordinary line, and the special section switch rail has symmetry and asymmetry Special section rail, no matter high type or short type.
