Test Results Report Metroliner Truck Improvement Program in Support of Test Request RR-254 : Volume 1

This report is divided into three volumes. Vol. I summarizes the testing procedures, describes the data reduction techniques and gives the results and conclusions. Vol. II describes Metroliner characteristics, modifications to Metroliner trucks, instrumentation, ride quality software and includes...

Techniques for Improving the Railroad Maintenance-of-Way Equipment Evaluation Process

This report presents the results of a study of techniques for improving the railroad maintenance-of-way equipment evaluation process. The approach involved a review of existing methods, interviews with equipment manufacturers and railroads, discussions with industry representatives, and an...

Technical Feasibility Study of Railroad Electrification with High Voltage (10-50kV) Direct Current

High-voltage (10-50 kV), direct-current (HVDC) power distribution may prove to be an economically and technically attractive option for railroad electrification. There may be potential economic advantages in both wayside installation and operation, and in the propulsion equipment aboard the rolling...

Technical Feasibility of Magnetic Levitation as a Suspension System for High-Speed Ground Transportation Vehicles- Volume II: Appendix

This report examines the technical feasibility of magnetic levitation as a suspension system for high-speed ground transportation vehicles in the 300 mph cruise speed range. Of the various magnetic suspensions which have been proposed only one appears to provide all of the desired features: good...

Summary Report-Ballast and Foundation Materials Research Program

This report constitutes a summary of the results of the various phases of the Ballast and Foundation Materials Research Program. Data and information obtained from the technical literature and that developed in the project are summarized. Implications of the research data and findings are discussed...

Study of New Track Structure Design Phase II

Phase I of this research investigation was undertaken in September, 1966, for the Office of High Speed Ground Transportation (OHSGT) of the Department of Commerce by Battelle Memorial Institute for the purpose of conceiving new and improved track structures for high-speed trains. As a result of...

Study of New Track Structure Design Phase I

Conventional (tie-type) and non-conventional rail vehicle track structures were studied with the constraint that standard gage and rail head contour not be varied from current practices. Computer programs were developed and used to analyze track response to both static and dynamic vehicle...

Study of Liability, Insurance and Indemnification Problems for FRA Programs

This report presents the findings, conclusions and recommendations of an extensive six-month study of liability, insurance and indemnification problems in certain FRA programs. To assemble this information, interviews were conducted, extensive legal research was performed, and relevant literature...

Studies for Rail Vehicle Track Structures

Conventional (tie-type) and non-conventional rail vehicle track structures were studied, with the restriction that standard gage and rail-head contour be used. Computer programs were developed and used to analyze track response to both static and dynamic vehicle loading. The models of...

Development of a Structural Model and Materials Evaluation Procedures- Ballast and Foundation Materials Research Program

An adequate engineering analysis of conventional railway track support system (CRTSS) requires the consideration of all the major components of the track support system. Past efforts in this area have not been satisfactory because of lack of proper material characterization and very simplified...
