Study to Establish Ride Comfort Criteria for High Speed Magnetically Levitated Transportation Systems

The ride motions of a Maglev system were simulated by performing specific vertical and roll maneuvers in a small executive jet aircraft. After each maneuver the passenger subjects recorded a comfort rating on a 7-point scale from very comfortable to very uncomfortable. The vertical accelerations of...

Verification Methodology for Fault-Tolerant, Fail-Safe Computers Applied to Maglev Control Computer System

The Maglev control computer system should be designed to verifiably possess high reliability and safety as well as high availability to make Maglev a dependable and attractive transportation alternative to the public. A Maglev computer system has been designed using a design-for-validation...

Final Report on Magnetic and Electric Field Testing of the French Train A Grande Vitesse-Atlantique (TGV-A) Rail Systems Volume I- Analysis

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...

Evaluation of Wheel/Rail Contact Mechanics: Concepts Report

A need exists for a new test rig design with advanced sensing technologies that will allow the railroad industry and regulatory agencies to better understand the wheel-rail contact dynamics and mechanics, especially as it pertains to high-speed rail. Both scaled and full-scale designs are being...

The Aerodynamic Effects of High-Speed Trains on People and Property at Stations in the Northeast Corridor

This report presents the results of a study to evaluate the aerodynamic (air velocity and pressure) effects of the new high-speed trains on the safety and comfort of people and the impacts on physical facilities in and around Northeast Corridor stations. This report focuses particularly on the...

Task Force Report on the M-2 Axle/Bearing Failure Investigation

This investigation of the tubular-axle/roller-bearing failures experienced with M-2 multiple-unit cars of New York's Metropolitan Transportation Authority was aimed at establishing failure mechanisms, assessing the effectiveness of interim and long-term countermeasures, and determining if the risk...
