Evaluation of Two Prototype Devices for Non-Destructively Measuring Stresses in Railroad Wheels
Two devices designed to non-destructively determine the residual stress state of railroad wheels were evaluated. The first device was a magnetoacoustic design developed by the National Aeronautics and Space Administration, Langley Research Center in conjunction with the Association of American...
Evaluation of Concepts for Safe Speed Enforcement
This final report evaluates the suitability of existing and developmental safe speed enforcement concepts/systems for application to a high-speed maglev control system in the U.S.. Requirements, functions and needs are identified and discussed for two major aspects of safe speed enforcement: 1)...Effects of Disclosure Requirements on Railroad Grain Transportation Contracts
The Staggers Act of 1980 legalized confidential rail/shipper transportation contracts. Their acceptance by railroads and shippers is best demonstrated by the exponential growth of these contracts through the 1980s. In 1986, Congress mandated considerable disclosure in transportation contracts for...Effects of Disclosure Requirements on Railroad Grain Transportation Contracts (Appendices)
The Staggers Act of 1980 legalized confidential rail/shipper transportation contracts. Their acceptance by railroads and shippers is best demonstrated by the exponential growth of these contracts through the 1980s. In 1986, Congress mandated considerable disclosure in transportation contracts for...Conceptual Requirements of the Superconducting Linear Induction Motor
This study is a feasibility and conceptual design study of a superconducting linear induction motor for Maglev applications. Superconducting materials are maturing to the extent that a superconducting linear motor can be built with existing niobium titanium superconducting technology. Several...Conceptual Requirements of the Superconducting Linear Induction Motor
This study is a feasibility and conceptual design study of a superconducting linear induction motor for Maglev applications. Superconducting materials are maturing to the extent that a superconducting linear motor can be built with existing niobium titanium superconducting technology. Several...Comparison of Major Parameters in Electrodynamic and Electromagnetic Levitation Transport Systems
This study compiles quantitative design information that can be used in selecting a high-speed magnetic levitation system. Analytic models were developed for three configurations of electromagnetic (EMS) and three electrodynamie (EDS) systems, and for linear induction and synchronous motors. The...
Commuter-Intercity Rail Improvement Study (Boston-New York)
This study documents potential system improvements to benefit commuter and intercity rail passenger service in the Boston-New York corridor. The study was conducted by the Volpe National Transportation Systems Center (VNTSC) for the Department of Transportation under the direction of a Task...
