COST SAVINGS POTENTIAL OF MODIFICATIONS TO THE STANDARD LIGHT RAIL VEHICLE SPECIFICATION
This report describes an assessment of the Standard Light Rail Vehicle (SLRV) specification to determine whether the relaxation or modification of some requirements could result in a significant reduction in vehicle costs. A Technique of Assessment by Structured Interviewing was applied to include judgments and ideas by each facet of the industry concerning modifications to the specification which would be acceptable and could reduce car costs. A five-stage filtering process was used to select 20 cost reducing modifications from an initial list of 640 candidate specification modifications. The large list resulted from an in-depth review of the current specification. The final set of 20 areas were analyzed quantitatively to estimate cost savings that might be realized. SLRV cost savings of 16 percent are shown to result by implementing the 15 specification modifications which are termed as having acceptable impact upon mission performance. The remaining five modifications have major impact upon mission performance (e.g., unidirectional operation, doors on only one side, simplified friction brakes, no articulation, and elimination of compressed air). Cost savings of 25 percent are shown to result from specifying a bidirectional, non-articulated car with simplified friction brakes and no compressed air and which also incorporates the 15 specification modifications with acceptable impact on mission performance.
