Abstract
The Facility for Accelerated Service Testing (FAST), located at the Transportation Test Center near Pueblo, Colorado, is a joint government/industry program for accelerated life cycle testing of railroad track and mechanical components. The facility consists of a 4.8-mile loop around which a freight train of approximately 9,500 tons travels for 15 hours per day, 5 days per week. Measurements are taken periodically on various track and train components for the purpose of studying design performance and wear characteristics. As part of this overall program, a wheel experiment was designed to compare the performance of various types of wheels now in service on U.S. railroads. This report discusses an analysis of wheel wear data from the first wheel experiment, which ran from September 1976 to August 1977. Six wheel variables (heat-treated versus non-heat-treated, cast versus wrought, 1-wear versus 2-wear, AAR profile versus CN profile, 14-inch center plate versus 16-inch center plate, and type 1 truck versus type two truck) were studied. The analysis includes graphical analysis and the development of a regression model for studying variable interactions.
