The cost and performance benefits of using improved suspensions in passenger railcars are investigated. Preliminary results from the first year of a two year study are presented. The primary objective is to determine if improved vehicle suspensions can reduce overall system cost by allowing lower guideway maintenance standards. Cost determinations are limited to guideway annual maintenance and vehicle suspension installation and maintenance. The guideway/suspension system is divided into several areas which are analyzed separately. In Part I, transfer function models of passenger railcar and bus dynamics, and power spectral density models of guideway disturbances are developed. Preliminary guideway and suspension cost data are also analyzed.
