WebFatigue of Rails and Wheels Wheel Fatigue Technological advancements in the railway industry have made possible longer wear lives of wheels. Simultaneously, current economical and logistical needs demand increased train speeds and load capacities. These demands result in larger contact forces acting on rails and wheels. WebA sensitivity analysis suggests that the distribution of freight train miles by FRA track class may have changed since a study conducted by the Association of American Railroads in the early 1990s. More up-to-date estimates of track class-specific accident rates would require new data on this distribution.
