Assessment of the Technical Condition of the Automatic Coupling Device and Modern Methods of Restoring the Railcar's Resource

Abstract

Based on annual railcar repair reports, the probabilities of various automatic coupling failures are calculated, and a railcar decommissioning trend is plotted, with a forecast for the next three years. Modern diagnostic methods for automatic coupling devices, as well as surfacing methods for restoring worn parts, are considered. The advantages and disadvantages of surfacing methods are analyzed.
