The report describes a test program which has been conducted to establish baseline noise levels and ride characteristics for a state-of-the-art steel wheel on steel rail personalized rapid transit vehicle. A full-scale test vehicle and an 840-foot track, including two 30-foot curves, have been built and used for 128 test runs under various conditions of operation. Permanent records have been made on magnetic tape and oscillograph paper for future analysis as needed. The vehicle has been successfully demonstrated and has met speed and acceleration design goals. Noise levels of 82 to 85 dB(A) have substantially exceeded proposed criteria for both tangent track and curve track. The ride vibration has met current criteria on tangent track to the 30-mph test speed and to a 5-mph speed limit on the tight 30-foot curve track. There is some tendency to vehicle-hunting.
