RAIL ANALYSIS. VOLUME 3: STATISTICAL ANALYSIS OF RAIL DEFECT DATA
Rail defect data from six locations on American railroads are summarized and analyzed using Wiebull probability distributions. A five-fold difference in rail sites was found to be statistically significant. Rail defect life was found to vary with the fourth power of stress which explains high defect rates in lighter rail under the same loading conditions. Equations for defect occurrence as a function of traffic and stress are given.
