Early research and development efforts by the Urban Mass Transportion Administration (UMTA) in the area of urban rail transit were long range programs attempting to apply advanced technology to problems plaguing U.S. transit properties. The programs themselves are known collectively as Subsystem Technology Applications to Rail Systems (STARS). This study of electromagnetic interference (EMI) characteristics of advanced propulsion systems, directed toward resolving total systems problems with EMI, is a part of a larger STARS program. This report describes various track circuit signalling systems and identifies different modes of possible EMI from onboard electrical power subsystems for urban rail vehicles. Chopper controlled ac drives and inverter controlled ac drives are analyzed and characterized as electromagnetic noise sources. Waveforms of currents through various reactors in the drive circuity are presented. Finally, eleven different chopper circuit configurations are analyzed in detail Appendix A and the characteristics of multiple-car trains are reviewed in Appendix B.
