KEYWORDS: Risk Assessment, Railroad Technology, Risk Mitigation
ABSTRACT: Transportation specialists have pointed to the inherent advantages of magnetic levitation (maglev) system architectures that include dedicated guideway which precludes many potential collision hazards. Use of a synchronous motor has been cited as contributing to reduced risk of two trains colliding. These observations and others have been shown to be oversimplifications through studies performed by Transrapid International; TUV Rhineland; and the U.S. Department of Transportation, Federal Railroad Administration, and is corroborated by this study. While some potential maglev architectures contain features of inherent safety and high reliability, risks associated with highspeed ground transportation have potentially serious consequences, and therefore require careful consideration, analysis, and effective mitigation. This report documents the risks accompanying the potential hazards encountered by a maglev system. Risk mitigation is not presented as part of these findings. The hazards identified, and their associated risk assessments, are useful as a foundation for risk mitigation strategy definition and will support analyses during the early phases of system development. The report can assist the development of system safety requirements and the preparation of performance and design specifications.
