Tremendous efforts to the research and development have been devoted in the area of railroad industry. However, the rail accident of German railroad in 1998 clarified that we need to study more deeply. Even thought, Fracture Mechanics are now used as an ordinary tool to apply to design products, and knowledge of fatigue characteristics is common. This paper reports how the author has studied the railroad products. The issues the author thinks to be solved are whether fatigue limit exists based on the scientific explanation, whether the retardation of crack extension can happen with appropriate ground, and whether a crack extends under large compressive cyclic loading.
