Summary of Accidents Investigated by the Federal Railroad Administration: Calendar Year 1990
The 1990 Summary of Accidents Investigated by the Federal Railroad Administration (FRA) includes 240 railroad accidents. This summary provides the following information: the railroad(s) involved, the location and the time of the accident o the type of railroad accident, the method of operation and...State-of-the-Art Assessment of Guideway Systems for Maglev Applications
The engineering, environmental, diagnostic, and economic feasibility of Maglev guideway systems are assessed with an emphasis on composite materials as directed by Congress. This study further examines the performance and the cost of existing and innovative guideway systems that are applicable to...Sensor Systems for Monitoring Maglev Guideway Structures
This report is an assessment of the technologies available for continuous monitoring of the physical condition and structural integrity of maglev guideways. The detection of obstructions on the guideway is not included. No particular guideway design is assumed, other than that the largest part of...Safety of High Speed Magnetic Levitation Transportation Systems: Final Report on Magnetic Field Testing of TR-07 Maglev Vehicle, Volume I - Analysis
The safety of various magnetically levitated (maglev) and high speed rail (HSR) trains proposed for application in the United States is of direct concern to the Federal Railroad Administration (FRA). The characterization of electric and magnetic fields (EMF) emissions, both steady (dc) and...
Recommendations for Acoustical Test Facility for Maglev Research
Noise from high speed operations of a maglev system is a source of concern. The German and Japanese prototype maglev systems generate high noise levels at very high speeds. Without mitigation, a maglev system may encounter public opposition if introduced to the existing transportation system in the...Preliminary Design Guidelines for Noise Control on High Speed Maglev Trains
This report builds on the first two reports of this series and provides preliminary guidelines on the prediction, assessment and mitigation of noise from maglev systems. The first report identifies noise sources from high speed maglev operations and recommends further research to help determine the...Power Transfer to High Speed Vehicles
This final report summarizes work performed in the assessment and analysis of power transfer techniques to high speed vehicles. The objectives of this research were to determine the optimum power transfer technique for two power levels at high speed and to prepare a preliminary design of the...Novel Cryogen-free Actively Shielded Superconducting Magnets for Maglev Vehicles
This report presents the results of a research effort into the design of a shielded superconducting magnet system for a maglev vehicle. The magnet design is based on a novel cryogen-free technology which allows operation without the use of any cryogenic fluids. This is accomplished by the use of...
