ABSTRACT: The overall goals of the ACT-1 program were to enhance the attractiveness of urban rail transit and to apply advanced technology in elevating the state of the art of rapid rail transit car design. During Phase II of the program, two prototype advanced concept train cars were designed, fabricated, and tested through the joint efforts of the Urban Mass Transportation Administration, the American Public Transit Association, the Boeing-Vertol division of the Boeing Company, the AiResearch Manufacturing Company of California division of the Garrett Corporation, and fifteen major subcontractors. The design goal was to improve passenger comfort and appeal, economic and operating efficiency, and environmental impact through reassessment and innovation in all of the car's major systems: carbody, interior, propulsion, trucks, HVAC, doors, collision attenuation, auxiliary electrical system, pneumatics and brakes, train control, and communication system. The most important achievement was the development of a highly energy-efficient, electronically controlled propulsion system whose flywheel can store the energy released during vehicle braking for use in subsequent vehicle accelerations. Other important achievements included a lightweight monomotor truck; a fast- response friction brake system employing a chrome-copper disc for high energy absorption; a modular, vandal-resistant interior of high flame resistance and low smoke emissivity; and an on-board closed circuit television.
