The change of the ambient temperature will cause the temperature of the rail to change accordingly. At this time, the seamless line rail generates a temperature force, and the size of the temperature force is proportional to the rail temperature difference. When the temperature of the rail is higher than the temperature of the locked rail, the pressure is generated inside the rail of the seamless line, and the temperature of the rail is lower than the temperature of the locked rail, and the tension is generated inside the rail. When the temperature of the rail exceeds the allowable threshold, a large force will be generated inside the rail, which will have a great impact on the stability and safety of the seamless track.
