Field Characterization of Rail Friction

Leaders: Donald Eadie, consultant and Harold Harrison, OnTrak

Description: A series of field measurements will be undertaken on North American railroads using the “new” OnTrak tribometer to evaluate the effect of:

  • Wheel/rail creepage by identifying frictional differences between tangent, shallow and sharp curves
  • Load and longitudinal creepage on third body composition and friction.
  • Various friction modifying materials on measured friction

Status: Funding obtained for field work. Test plan in place. WebEx is planned for Nov/Dec 2017
