Magnetic levitation (maglev) technology has the potential to provide very high speed travel with the capacity and convenient access of conventional passenger railways, while relieving U.S. highway and airport congestion. A need exists for the assessment of the safety implications of this new form...
This report documents the low frequency electric and magnetic fields associated with the operation of the Massachusetts Bay Transit Authority's (MBTA) mass transit system in the Boston area. With excellent cooperation and assistance of MBTA personnel, comprehensive measurements were made on and...
This report docunents the procedures, events, and results of vehicle dynamic tests carried out on the ASEA-Brown Boveri (ABB) X2000 tilt body trainset in the U.S. between October 1992 and May 1993. These tests, sponsored by Amtrak and supported by the FRA, were conducted to assess the suitability...
In many areas of the country, potential U.S. applications for high-speed rail and maglev technologies are being considered. The Federal Railroad Administration (FRA) of the U.S. Department of Transportation has statutory responsibility to assure the safe operations of intercity high-speed rail and...
[From the Introduction] One of the duties of the Office of Intermodalism, specified in Title V of the Intermodal Surface Transportation Efficiency Act (ISTEA), is the development of an intermodal transportation data base. Section 5001(c) of the ISTEA states: "(4) INTERMODAL TRANSPORTATION DATA BASE...
[From the Introduction] This report presents plastic and residual strains corresponding to residual stresses obtained for two one-dimensional test problems using a thick-walled cylinder. General formulation of the problems was the same as in the test of torsion of a cylinder, presented in the...
Noise levels from magnetically-levitated trains (maglev) at very high speed may be high enough to cause environmental noise impact in residential areas. Aeroacoustic sources dominate the sound at high speeds and guideway vibrations generate noticeable sound at low speed. In addition, to high noise...
The physical and operational characteristics of four existing and planned maglev systems were surveyed pertinent to the intermoda! interface for each system. The maglev systems investigated were: Grumman "New York State" (Configuration 002) Maglev; Transrapid Intercity (Transrapid 07) Maglev; HSST...
