The part of rail joint becomes the cause of the disadvantage points such as ride discomfort, track maintenance, etc. For restraining those points, the long rail made by welding the standard length rails has been developed. However, the problems of the buckling caused by the axial force of the rail have been pointed out. Though some evaluation techniques for the buckling management are proposed, the development of the technique with non-destructive inspection which quantitatively evaluates the force is desired. In this study, the characteristics of ultrasonic echo for evaluating the force are reported.
