Track Support Systems Parameter Study- Ballast and Foundation Materials Research Program

A finite element structural analysis model for conventional railway track support systems (CRTSS) has previously been developed. This study includes parameter studies and sensitivity analyses conducted using the structural model to establish the effects of various parameters on the "instantaneous-...

Track Structure Design Using Mathematical Models

The objective of the report is to demonstrate the use of mathematical track structure models in the development of design charts. The f110dels have been developed in Task 1, Mathematical Modeling, of the Track Structures Research Program, Contract DOT-FR-30038. The charts should enable the optimal...

The Kansas Test Track Part II- Appendices

This report presents data obtained from an experimental project to compare the performance of different track support systems. Also, it describes instruments used for data measurement, their location in track, and test procedures. Analysis and evaluation of test data are presented in Part I of...

The Kansas Test Track

The Federal Railroad Administration and the Atchison, Topeka, & Santa Fe Railway Company are jointly sponsoring the construction of a test track as part of the railroad's heavy tonnage main line in Kansas. The objective of the project is a determination of the levels of increased train...

The Energy and Environmental Impact of Railroad Electrification

This report describes the potential effects of railroad electrification for high traffic density lines in the United States. Two high traffic density groupings of routes are identified as candidates for electrification. The primary group consists of eleven highly utilized routes with traffic...

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...

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...
