Advanced Power Conditioning for Maglev Systems

The final report contains parametric scaling data and computer models of power conditioning equipment applicable to the design of an advanced maglev system. The power conditioning topologies were selected based on data from a literature search, on characteristics of present power semiconductor...

Advanced Low-Cost, High-Performance Guideway Concepts

This report presents the results of a program to develop a high-performance, low -cost guideway configuration to meet the requirements of a United States Maglev system. This work initially involved research to identify and quantify the guideway design requirements specific to such a U.S. system...

A Comparison of U.S. and Foreign Safety Regulations for Potential Application to Maglev Systems

Under current legislation, the FRA has the responsibility for safety assurance of any maglev or high-speed rail system operated in public service in the United States. As part of its work to exercise this responsibility, the FRA, supported by Volpe National Transportation Systems Center (VNTSC...

Wheel/Truck Tolerance Experiment at FAST

The test program described in this report covers the investigation of the performance of trucks in freight cars influenced by various mechanical factors. The primary issue was the effect of axle misalignment on the behavior of three-piece trucks. Secondary tests were carried out to investigate the...

Safety Relevant Observations on the X2000 Tilting Train

[From the Background section] This report describes the background leading up to the development of the X2000, the potential U.S. applications, and the technology in some detail and finally reviews FRA regulations that may be applicable to the design of this train relative to any potential U.S....

Safety Relevant Observations on the TGV High Speed Train

This report describes the background leading up to the development of the train grande vitesse (TGV) system, the French high-speed technology; the technology itself in some detail; and the potential U.S. applications. This document also reviews Federal Railroad Administration (FRA) regulations that...

Safety of High Speed Magnetic Levitation Transportation Systems: Preliminary Safety Review of the Transrapid Maglev System

[From the Introduction] This Executive Summary of the first interim report, Safety of High Speed Magnetic Levitation Transportation Systems, presents a preliminary safety review of the Transrapid Maglev System intended for use in Orlando, Florida and between Anaheim, California and Las Vegas,...

Rail vs. Truck Fuel Efficiency: The Relative Fuel Efficiency of Truck Competitive Rail Freight and Truck Operations Compared in a Range of Corridors - Summary of Findings

This report summarizes the findings of a study to evaluate the fuel efficiency of rail freight operations relative to competing truckload service. The objective of the study was to identify the circumstances in which rail freight service offers a fuel efficiency advantage over alternative truckload...

Rail vs. Truck Fuel Efficiency: The Relative Fuel Efficiency of Truck Competitive Rail Freight and Truck Operations Compared in a Range of Corridors

Peacekeeper Rail Garrison Vehicle Characterization Test of Triplet Cars, ATSF 90004 and 90006

Vehicle Characterization tests were performed on two of three commercial span bolsters cars (Triplet Cars) to gather data in support of the Train Dynamics Model (TDM) prediction of coupled span bolster car performance. The three vehicle characterization tests were: (1) static suspension...
