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...

SOAC State-of-the-Art Car Engineering Tests at DOT High Speed Ground Test Center Final Test Report Volume II: Performance Tests

This six-volume report presents the technical methodology, data samples, and results of tests conducted on the SOAC on the Rail Transit Test Track at the High Speed Ground Test Center in Pueblo, Colorado during the period April to July 1973. The UMTA-sponsored Urban Rail Supporting Technology...

SOAC State-of-the-Art Car Engineering Tests at Depatment of Transportation High Speed Ground Test Center Final Test Report - Volume 1 Program Description and Test Summary

Service Analysis of Tube Vehicle Systems

This report describes an analysis of the service characteristics, cost and performance of Tube Vehicle Systems operating within the Northeast Corridor of the United States in the 1975 to 1985 time frame. The basis of this study is the TRANSOP computer program which, as described herein, searches...

Rock Fracture Research- Surfactants

In order to reduce the resistance of hard rocks to excavation by available cutters, and in order to reduce wear on cutters and thus to increase the efficiency of conventional tunneling machines and thus improve their rate of advance in hard rocks, surface active agents have been studied in...

Resistance of a Freight Train to Forward Motion- Volume II, Implementation and Assessment

This interim report is a supplement to a previous report and documents the results of the second portion of an investigation of the train resistance phenomenon. This portion of the effort was specifically directed toward determination of possible fuel savings to be effected through certain design...

Report on the 5th International Wheelsets Congress

A summary is given for each of the thirty technical papers presented at the International Wheelsets Congress held in Tokyo, Japan, 20-23 October 1975. The papers were presented by international experts in rail research and covered a wide range of wheel/rail topics, including dynamic forces,...
