This article describes a system for monitoring the presence of deflections gauge railway from the allowable size. We present a practical implementation of the system, which includes satellite navigation system for determining the basic parameters of the movement of rolling stock and inertial measuring devices for fixation of moving cars in the transverse direction. An algorithm for calculating the relative deflection of the trajectories of the cars while driving on the railroad track. Proposed options to improve the accuracy of the system by increasing the number of sensors and multiple repetitions of experiments. Analyzed the benefits of the system across the rail transport system.
