The rail damage characteristic and cause have been researched regarding the rail line with notable damage of nucleus flaw. Paving trial of the hot- rolled U76 CrRe and U75 V rail,and the heat treated U75 V and PG4 rail have been carried out in the section with notable damage of nucleus flaw in Cheng Kun line and Long Hai line. The results from research and trial indicates that the heat treated rails have better fatigue and nucleus flaw resistance than hot rolled rails. For the application in the line with notable damage of nucleus flaw,the heat treated rail has been suggested that rather than the hot- rolled rail.
