BR experience in the measurement of rail forces - a paper presented at the FRA/AAR conference on rail forces, February 1979 (TM-TS-107)

An essential feature of continuously welded rail (CWR) is the property of restrained thermal expansion. Over a typical rail temperature range this leads to the existence of large tensile and compressive forces and the possibility of rail breaks or buckles. BR have considerable interest in the control of longitudinal rail...
