The study of wear characteristics of Vidura wheel profile of the State Railway of Thailand (SRT) with collected data from field measurements is presented. This study represents the average values of wheel wear due to normal utilizations of the wheel on multiple routes of SRT. The data has been analyzed for characters of tread wear and flange wear with volumetric wear rates. The results show that the wear characteristic is non-linear in nature, and the average value of volumetric tread wear rate is 7.613714 mm3/km while the average value of volumetric flange wear rate is 1.47525 mm3/km.
