Study on Method for Assessing the Condition of Rail Corrugation and Glued-Insulated Joint Using Track Material Monitoring System

Abstract

Currently, the condition of track equipment and track materials is checked by track patrol and onboard track patrol. Track maintenance engineers perform this task at high frequency through visual inspection and dimensional measurement. To reduce those works, we developed two algorithms using images captured by the track material monitoring system in this study: one for extracting rail corrugation, and another for extracting metal flow at glued-insulated joints. The results of our study are reported below.
