GUIDEWAY - VEHICLE COST REDUCTION. PART II: ACTIVE SUSPENSION FEASIBILITY

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. In Part II, an assessment of active suspension feasibility is made which includes the preliminary design of a new low power pneumatic concept. A preliminary suspension/guideway maintenance cost tradeoff is described which shows that active suspensions are cost effective for low vehicle density routes.
