RESEARCH ON THE SIGNS OF TRACK BUCKLING USING ALIGNMENT.

Abstract

 Preventing track buckling is important for safety and reliability of transportation. For that reason, inspections are carried out to prevent track buckling. If the inspection result is poor, we will implement restressing of continuous welded rail. However, in recent years, track buckling have not been eradicated within JR East's jurisdiction. Therefore, in this study, we focused on alignment as a supplementary inspection. We analyzed how the precursors of track buckling affect the alignment. As a result of the study, in the process of track buckling, alignment is characterized by increasing with the increase in rail temperature. Therefore, by analyzing alignment data, it is possible to grasp the signs of track buckling. In addition, there is a possibility that planned countermeasures can be implemented.
