Noise Characteristics of the Transrapid TR08 Maglev System
REPORT NUMBER: DOT VNTSC-FRA-02-13
KEYWORDS: magnetic levitation, Maglev, noise, environment, high-speed ground transportation
ABSTRACT: As part of the Federal Railroad Administration’s (FRA) Magnetic Levitation Transportation Technology Deployment Program, this technical report has been prepared to characterize the noise associated with the operation of the Transrapid International (TRI) TR08 Maglev System. The TRI TR08 Maglev System is an advanced transportation technology in which magnetic forces levitate, propel, and guide a vehicle over a specially-designed guideway. The TR08 Maglev System is the technology that is being considered for deployment in the U.S., and potential noise impacts of the technology were not known. This document presents noise data collected during measurements of the TRI TR08 Maglev System in August 2001, and May 2002, at the TRI Test Facility in the Emsland region of Germany. Noise data presented for the TR08 include single-microphone and array data for various guideway types, as well as speed- and distance-based noise relationships. Noise data are also compared with other transportation technologies.
