Wheel Rail Interface

The Institute of Railway Technology has significant experience in solving wheel-rail interface related issues for a wide range of operating conditions, including heavy haul, general freight, mass transit and high speed rail.

Key areas of expertise include:

  • Assessment of damage mechanisms in wheel-rail contact:
    • Wear
    • Rolling contact fatigue
    • Corrugations
  • Wheel-rail contact modelling
  • Design and implementation of wheel and rail profiles
  • Development of rail profiling procedures and practices
  • Assessment of wheel and rail material behaviour
  • Lubrication and friction management
  • Wheel-rail noise

Considerable benefits can be gained through appropriate wheel-rail interface management, including reduced defect rates, improved safety, extended wheel and rail life, improved vehicle-track interaction, reduced wheel-rail noise and the development of suitable standards and maintenance procedures.
