2021 Principles Course Session
Maintaining the Optimized Wheel-Rail Interface Conditions
NRC - Canada
Building on the framework established in the preceding sessions, the use of key targets, specifications, measurement systems and maintenance practices to establish and maintain an optimized wheel-rail interface is discussed. This includes maintenance technologies and practices to establish and maintain rail and wheel profiles and their surface condition through grinding/milling and truing/turning. Friction management technologies are also reviewed from the standpoint of available technologies for optimizing and maintaining optimized wheel-rail system performance for prolonged periods.
