ABSTRACT: The safety of magenetically levitated (maglev) and high speed rail (HSR) trains proposed for application in the United States is the responsibility of the Federal Railroad Administraion (FRA). A franchise has been awarded to the Texas High Speed Rail Corporation to operate a 200 mph 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. II, Appendices) of representative electric and magentic field (EMF) profiles on TGV-A trains between Paris and Tours for two electro-technologies (1.5 KV DC near Paris, and 2x25 KV 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 moitoring 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 tocollect 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 Low Frequency (ELF) levels for the TGV system are comparable to thos produced by common home, work, and power lines. EMF field levels are for the TGV rail system components are within the ranges of other common environmental EMF sources, but have specific frequency signatures.
