Measurements of transverse section wear of rails in tracks of tram-loop

Abstract

In article the problems of classical methods of transverse section wear of rails replacement with new techniques based on electronic devices was concerned. Reasons of rails shape section changes were defined. Principles of rails waste inspection resulting from regulations were reminded. Review of practical measurement methods and devices were made. Shapes of nominal sections of rails used in tram tracks were analyzed. Realization of measurements executed with mechanical-electronic profile gauge and mechanical track gauge on tram-loop Sępolno in Wrocław were described. Proposal of graphic manner analysis of rail wear measurements in connection with track width measurements were proposed. In summary conclusions from effected investigations were formulated.
