In the past decade, advances in the technology of instrumentation and of computers have made possible the determination of wheel/rail loads so that proper design and maintenance procedures may be developed for vehicles and track so that the industry can live with today's axle loadings. Methods of determining such loads by measurements on the vehicle and the track are discussed. Mathematical modeling procedures may also be utilized to calculate such loads. Computer simulation which includes both vehicle and track in a dynamic interacting system permits specification of outputs in the form of vertical and lateral forces between wheel and rail. Some of the research programs in load determination are then described.
