Abstract—Some results of experimental studies on the deformation of a rail under the force impact of a moving railway vehicle were presented. The studies were performed by using a supersensitive strain sensor with an ultimate relative strain of $2\times 10^{-7}$. The capabilities of optical tensometry in the problems of monitoring the technical state of wagon bogies and the upper structure of railways were analyzed.
