This paper describes the analytical, design, and test processes utilized in development of a cross-braced freight car truck intended for service on American railroads. Analytical techniques predict the stability boundaries and curving characteristics, and suggest ranges of suspension parameters to satisfy various service conditions. Within the constraints normally placed on truck suspension systems, a viable design is evolved and the system is further qualified by extensive dynamic testing.
