Purpose: The aim of the paper is to optimize the metrological maintenance of dynamic scales for railway wagons and trains by applying modern methods of analysis and improving the accuracy and reliability of measurements. The paper studies the methodology for verifying dynamic scales, and presents a table of inspection schedule that ensures timely and systematic metrological maintenance. An analysis of the number of dynamic scales and the stations where they are installed was carried out. This enabled the assessment of the future work scale. Based on the data obtained, recommendations have been developed to improve the verification and calibration processes aimed at reducing measurement errors and improving the efficiency of weighing equipment functionality. The research results can be used to optimize the operation of railway transport and reduce maintenance costs. Methods: Analysis of the existing methodology for calibrating dynamic scales; development of a new testing method for calibrating scales; and modelling the verification process using a new test train. Results: The shortcomings of dynamic scales verification have been identified. A new method for their verification by a test train has been developed. The simulation has demonstrated that the new test train is capable of significantly reducing the verification time while increasing its accuracy, reducing the logistical burden on locomotives and railways. Practical significance: A new method for using a test train to calibrate dynamic scales at railway stations has been proposed. A test train route has been developed to ensure the verification of all scales on the Oktyabrskaya Railway; the frequency and procedure for calibrating the scales have also been determined. The research was conducted by analyzing data acquired from the verification of dynamic scales at railway stations operated by the Oktyabrskaya Railway. Adopting the suggested recommendations would facilitate uninterrupted operations and decrease expenses related to metrological maintenance.
