ABSTRACT
The article focuses on high-speed grinding as a preventive technique that gently removes embrittlement and cracks in the rail surface. It notes the rise in the number of corrugations and cracks caused by rolling contact fatigue and explains the three phases of a crack's history. It also highlights the advantages of high-speed grinding over conventional grinding, and describes Vossloh Rail Services' high-speed grinding train deployed in Germany and its second generation train HSG-2.
