This handbook includes chapters dealing with the technology of lime injection, surface and subsurface soil exploration and laboratory testing, environmental considerations and safety precautions. In addition, there are appendices which provide state-of-the-art specifications for lime slurry...

Evaluation of Signal/Control System Equipment and Technology: Task 3 - Standardization, Signal Types, Titles

This report analyzes and summarizes current signal types and associated aspects, titles and indications employed by U. S. Railroads over which Amtrak operates as well as by several foreign railroads. A review of the historical development of signal technology is presented. The report concludes...

Evaluation of Signal/Control System Equipment and Technology: Task 2 - Status of Present Signal/Control Equipment

[From the Preface] This report results from research supported by the Department of Transportation, Federal Railroad Administration, Office of Research and Development, for the following seven separate but interrelated tasks under Contract DOT-FR-773- 4236: "Evaluation and Assessment of Signal/...

Engineering Data on Selected High Speed Passenger Trucks (Reprint)

The purpose of this Project is to compile a list of high speed truck engineering parameters for characterization in dynamic performance modeling activities. Data tabulations are supplied for trucks from France, Germany, Italy, England, Japan, U.S.S.R., Canada and The United States.

Effects of Rail Vehicle Size: A Special Bibliography

This document contains abstracts of documents related to the size, weight, or length of rail vehicles. These abstracts are drawn from the magnetic tape files of the Railroad Research Information Service (RRIS). These files are comprised of abstracts of technical reports, journal articles, and...

Effect of Torsional Fastener Resistance on the Lateral Response of a Rail-Tie Structure

The use of the classical beam bending equations for the analysis of the track response in the lateral plane is of questionable validity; when the used fasteners exhibit a noticeable torsional resistance. To remedy this situation, recently a variety of other track equations were proposed and used....

Dynamic Loads on the Undercarriage of Freight Cars

A description is presented of the procedure and the equipment used to study the dynamic loads acting on the undercarriages of freight cars. The results are presented from testing the four axle and eight axle gondolas and tank cars on the primary routes of the railroad network as part of operating...

Braking and Coupling Systems Design Optimization

This program review details the methodology, existing equipment, and innovative concepts in braking and coupling system design.

Analysis of Data from the First Wheel Experiment at the Facility for Accelerated Service Testing: Final Report

The Facility for Accelerated Service Testing (FAST), located at the Transportation Test Center near Pueblo, Colorado, is a joint government/ industry program for accelerated life cycle testing of railroad track and mechanical components. The facility consists of a 4.8-mile loop around which a...

Aerodynamic Forces on Various Configurations of Railroad Cars and Carrying Trailers and Containers

Toward improving the energy efficiency of rail intermodal service, the aerodynamic characteristics of the rolling stock offer a significant opportunity for betterment. At speeds above 45 miles per hour more than half of the resistance of an intermodal train is caused by the aerodynamic drag of the...
