THE "CALIBRATED LENGTH OF RAIL" METHOD FOR MEASURING RAIL TEMPERATURE STRESS

Continuous Welded Rail (CWR) has been widely used all over the world. The key issues in the CWR technology is to accurately measure actual rail temperature stress through rail neutral temperature or rail anchored temperature. The traditional length concept was formed and evolved in the past thousand years, where the "meter" standard system was established several hundred years ago. A new concept has been proposed, "instantaneous natural length", and a new method has been found, "Calibrated Length of Rail (CLR). This paper will solve the issues of accurately measuring temperature stress of CWR.
