Possibilities of using fiber-optic sensors in train movement control systems Merab Gotsadze, Avtandil Sharvashidze, Tengiz Tabidze Abstract: The article deals with the possibilities of using a new element base in control systems and ensuring the safety of train traffic in the form of a fiber-optic sensor for measuring temperature and deformation of railway objects. Instead of the currently operating traditional rail schemes, a discrete sensor built on a fiber-optic sensor is offered, providing complete information on the state of the tracks. A sensor fiber-optical information-measuring system has been developed, providing a significant economic effect.
