Abstract. The problem of improvement of principles of management and control in railway transport is dis-cussed. The possibility of using optical sensors in railways traffic control systems instead of traditional electric current track circuits is considered. The way of installation and fastening of sensors to railway rails is described, as well as the principle of integration into the control system. A block diagram of the system for recording the parameters of moving units based on optical sensors is given. Results of experimental studies of sensors on Shushary railroad hump yard of October Railway are demonstrated. It is shown that optical sensors can be used not only for positioning of mobile units, but also for measurement of several critical parameters of the units. The results presented in the paper are regarded as a first step towards the transition to a fundamentally new method for controlling the movement of trains based on optical technologies.
Keywords: train traffic management systems, railway automation and remote control, optical sensor, registration of parameters, electrical centralization, quantum centralization
