ABSTRACT: The safety of magnetically Levitated (maglev) end high speed rail (HSR) trains proposed for application in the United States is the responsibility of the Federal Railroad Administration (FRA). A franchise has been awarded to the Texas High Speed Rail Corporation to operate a 200 French Train a Grande Vitesse (TGV) in the Texas Triangle (Dallas-Fort Worth, Houston, San Antonio), with construction to begin in 1995. This report provides the Analysis (Vol. I) of results, and detailed data and statistical summaries (Vol. 11, Appendices) of representative electric and magnetic field (EMF) profiles on TGV-A trains between Paris and Tours for two electro- technologies (1.5 KV DC near Paris, and 2x25 KI at 50 Hz AC). EMF data represent a range of train operating conditions and Locations (in vehicles, stations and wayside), as well as in traffic control and electrical facilities. A portable magnetic field monitoring system (augmented to include an electric fields probe) was used to sample, record and store 3 axis static and AC magnetic fields waveforms simultaneously, at multiple Locations. A real time Digital Audio Tape (DAT) recorder able to capture EMF transients, and two personal power-frequency magnetic field monitors were used to collect complementary data. The statistical and Fourier analysis of results in Volume I-Analysis enable a comparative characterization of EMF intensities, and spatial and temporal variability, by frequency band, and by distance from the source. EMF Extra Lou Frequency (ELF) Levels for the TGV system are comparable to those produces by common home, work, and power Lines. EMF field Levels for the TGV rail system components are within the ranges of other common environmental EMF sources, but have specific frequency signatures. Volume 11-Amendices catalogs and documents detailed data files by electro- technology, source and Location.
