Abstract
The results of experimental studies of the deformation of a rail under the force of a moving railway transport are presented. The studies are carried out using a highly sensitive deformation sensor with a limit level of relative deformation of 2 · 10-7 . The possibilities of optical strain measurement for solving the problem of monitoring the technical condition of the running gear of wagons and the upper structure of the track are analyzed.
