The Effects of Accelerated Ballast Consolidation

The effects of accelerated ballast consolidation were tested on mainline tracks of the Boston and Maine, the Chessie, the Missouri Pacific, the Penn Central and the Saint Louis and Southwestern, and at three sites on the Southern. Tests were made before and after traffic, after surfacing and...

Test Train Program- Ninth Progress Report

This report describes progress on the Engineering and Test Support Services for Railroad Instrumentation, Data Acquisition, Processing and Evaluation Program from 1 July 1976 through 30 June 1977. The report covers operation of the FRA track geometry measurement and data acquisition fleet, track...

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...
