ABSTRACT: This report was prepared as part of the Improved Track Structures Research Program sponsored by the Office of Rail Safety Research of the Federal Railroad Administration. A survey of available wheel/rail load data was conducted (see the Interim Report, D0T-TSC-1051, April, 1976) and noticeable gaps in the existing data and formats of presentation were reported. In this report a test plan for gathering a comprehensive set of wheel/rail load data from both trackside and vehicle-borne transducer measurements is outlined. Primary uses of the resulting data will include the characterization of wheel/rail .loads under revenue- traffic at a representative track site, the characterization of wheel/rail loads from a representative vehicle (a 100-ton freight car) over varied track conditions, and validation of load-predictive models by comparison of computed and measured response.
