ABSTRACT: A prototype single car, intended for use on revenue (Niagara Frontier Transportation Authority - NFTA) line in Buffalo, New York, was tested over a twelve-week period by the Association of American Railroads (AAR). Testing at the Transportation Test Center (TTC) in Pueblo, Colorado, was sponsored by the Office of Systems Engineering of the Urban Mass Transportation Administration (UMTA). The car was manufactured by the Tokyo Car Corporation of Japan, and utilized a Westinghouse propulsion system and Knorr friction brakes. Through the combined efforts of personnel from the Tokyo Car Corporation, the AAR/TTC, and additional subcontractors and consultants, the car was fitted with comprehensive instrumentation and prepared for testing in areas of acceleration/deceleration, power consumption, noise, ride quality, and overall performance under simulated revenue service profiles (duty cycle). Data reduction was performed by the staff of the TTC resulting in the following conclusions. Generally, the car satisfied specification criteria outlined in the test requirements with some minor exceptions. Reliability was excellent for all systems. One instance of propulsion motor flash-over occurred during a duty cycle run, but could not be duplicated subsequently. Friction braking, though criteria were met, evidenced low thermal capacity. Generally, system adjustments and alignments allowed for obtaining optimum performance. However, some settings were observed to be quite critical, thus indicating a need to carefully follow setup and adjustment procedures in preparation for revenue service.
