在英国，2000年的哈特菲尔德脱轨事故是由轨距角裂纹引起的，这是一种滚动接触疲劳。描述了轮轨接触引起钢轨裂纹萌生和扩展的过程。钢轨裂纹的产生和扩展取决于轴重、速度、铁路超高、钢轨表面质量、车轮圆度、轨道刚度和车辆悬挂。谢菲尔德大学使用德比AEAT铁路公司的数据开发了一个全寿命模型，以预测和控制由于车轮的循环载荷而在钢轨中发生的退化过程。
In the UK, the Hatfield derailment in 2000 was caused by gauge corner cracking, which is a form of rolling contact fatigue. The cracking initiation and crack propagation processes that occur in rails as a result of contact between wheels and rails are described. Crack initiation and growth in rails depends on axle load, speed, cant, the quality of the rail surface, wheel roundness, track stiffness, and vehicle suspensions. A whole life model was developed by the University of Sheffield using data from AEAT Rail at Derby to predict and control the degradation processes occurring in the rail as a result of cyclic loading by the wheels.
