Protran Technology’s EcoGrind tool compares the benefits of rail grinding versus a base case of no-grinding. EcoGrind evaluates the costs on an annual basis, and it creates a value analysis based on the unit costs and cycle of maintenance. A return on investment (ROI) is determined by using the benefits of grinding and the costs of grinding.

EcoGrind incorporates specific site and operation details including: segment length, curvature, annual tonnage, wheel load, level of lubrication, and type of grinding. This helps determine the life cycle of the various track components and maintenance activities that benefit from grinding


  • Extension in rail life
  • Reduction in fatigue defects
  • Decrease in surfacing cycle
  • Lessening in derailment risk
  • Drop in fuel costs
