Abstract
[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT The authors solve the problem of determination of operational risks relating to elements of a railway track under increasing over time changes in the track geometry due to weakening or breakdown of clip-bolt intermediate fastenings. To evaluate fastenings’ failures a method is offered based on the use of a parameter of rails’ displacement under train load. The parameter can be obtained by using automated diagnostic devices type KVL-P, ADK-I and «ERA» and similar to them. The article provides calculation of rail head displacement value, depending on the number of defective fastenings. The conditions for method’ s application are stipulated. Keywords: railway, railway track, operational risks, failures of rail clip- bolt fastenings, evaluation method.
