Abstract This paper chronicles the efforts of BNSF Railway, a North American heavy haul railway, together with its grinding contractor, to further optimize grind cycles and metal removal requirements to most economically control RCF damage. A new grinding methodology called Predictive Preventive Rail Grinding (PPG), developed by National Research Council Canada (NRC), is tested on a portion of the railroad. Detailed measurements from eight grind cycles over the course of 2 years are used to compare actual rail surface conditions vs. the PPG model.
