EVALUATION OF FOUR DIFFERENT RAIL RAPID TRANSIT PROPULSION SYSTEMS
At UMTA request, APTA evaluated four different propulsion systems. Due to lack of precise estimates for acquisition, maintenance, and traction power savings, this analysis is qualitative and adheres to the guideline that system elements will be compared subjectively, based on known design features and conservative extrapolation. A comparison was made of Garrett's flywheel energy storage, GE's AC propulsion (pulse-width modulation - PWM), Delco's self-synchronous motor, and a regenerative chopper to determine life cycle costs and related factors that would impact on eventual selection and application for revenue service.
