The procedure for putting into production traction and non-traction rolling stock and their elemental base, operated on the infrastructure of JSC Russian Railways, by enterprises of the machine-building and repair complex in order to establish a new assigned service life for them

Objective: consider the procedure for existing procedures for assessing rolling stock for the possibility of extending its actual service life using existing methods. To study the current procedures for extending the service life of locomotives and passenger cars by actually assessing the technical condition of each unit of rolling stock by conducting technical diagnostics on it, based on the results of which a decision is made to set a new assigned period (resource). Methods: comparison of procedures for extending the service life of traction and non-traction rolling stock. Assessment and identification of elements of traction rolling stock and locomotive-hauled passenger cars most susceptible to corrosion and fatigue failure. Analysis of the existing regulatory and technical framework and procedures for diagnosing locomotives and passenger cars for a possible decision on whether to carry out the procedure for extending the actual service life. Result: the reasons for limiting the procedure for establishing a new assigned service life for rolling stock have been established and scientifically based proposals for updating regulatory documents have been given. An extended model of technical preparation of production is proposed, taking into account the consideration of the main system stages. The areas most susceptible to wear and tear during the operational period have been identified in order to carry out preventive measures to eliminate them in a timely manner. Five main directions have been formed to ensure the legitimate operation of rolling stock upon expiration of its service life and obtaining a result on the possibility of its further use. Practical significance: creation of a procedure for establishing a new assigned service life (resource) for rolling stock, allowing structural enterprises of locomotive and passenger complexes to ensure interaction with their developers and manufacturers regarding the implementation of this process.
