Rolling Contact Fatigue (RCF) can occur on wheels and rails in passenger and freight railroads. It can be a significant cost driver, and, if left untreated, it may lead to derailments. Tangential wheel-rail forces, creepage and contract stress are shown to be the causes of RCF. Improved vehicle curving performance and optimized wheel and rail profiles are shown to have benefits. Methods of managing RCF are preventive rail grinding and wheel turning. Improved wheel and rail materials can also have benefits. The paper includes examples of rail and wheel RCF in both passenger and freight railroads. References are given to other papers for further reading on this subject.
