Summary:Rolling contact fatigue defects have always plagued North American railway operators, and as the demand for higher axle loads and faster train speeds increase so do the occurrences of RCF defects. In the mid-1980s, the NRC-CSTT developed the concept of preventive rail grinding as a rail maintenance strategy to help control RCF defects and to prolong rail asset life. This grinding method was based on available research concerning RCF crack initiation and propagation.
