The report presents the results of the research aimed at justification of expediency of creating a system of experimental evaluation of indicators of impact of the rolling stock on the rails. The proposed system is based on the measurements of the vertical and horizontal accelerations of the rails under a movement of the rolling stock on the raił track section. This system for monitoring rail accelerations that are emerging from the impact of the rolling stock in the track structure is expected to be used to identify vehicles with high impact on the rails due to their design and technical condition of the running gears, including the defects of the wheels. Some results of the pilot testing of the proposed system for the monitoring of the accelerations, which were registered by passing the train consisting of five units, are presented. And the computational algorithm of the specialized pre-processing of the multidimensional signal that is recorded by this system is described. The offered algorithm in automatic mode allows dividing the signal on the separate segments that are associated with the particular wheelsof a running train for subsequent analysis of each segment. This algorithm does not reąuire input data about the train speed on the track section that is eąuipped with the monitoring system, about the number of wheelsets of the running train, and about the distances between them. These data are calculated as a result of the algorithm execution, sińce they are absent under the operating conditions of the proposed system.
