An Update of the Costs and Benefits of Railroad Electrification

This report contains material for use by the Federal Railroad Administration in reassessment of railroad electrification. The costs and benefits of electrification compared to continued diesel operation are established by calculating the rate of return on the differential cash flow. The rate of...

An Overview of Electricity Pricing Policies and Practices Applied to Railroad Electrification

This report contains material for use by the Federal Railroad Administration in its assessment of railroad electrification. An overview is provided of the current policies and practices of the electric utility industry in its pricing of electricity. The application of current practice to...

Accident/Incident Bulletin No. 148

This report documents all incidents/accidents during the 1979 calendar year.

A Prototype Maintenance-of-Way Planning System Volume I: Final Report Including Appendices A through E

The results of this study substantiate the concept of using automatic track inspection vehicles as a tool in Maintenance-of-Way planning. This study is based on data collected over a period of one year on 288 miles of CONRAIL mainline track. Track geometry was measured using an FRA Track Geometry...

A Description of the Tests Conducted and Data Obtained During the Perturbed Track Test

This report describes the Perturbed Track Test, Pilot Test and Freight Test conducted at the Transportation Test Center in Pueblo, Colorado, in November and December 1978, August 1978, and February 1979, respectively. The tests involved two typical AMTRAK six-axle locomotives and two typical...

WMATA Rapid Transit Vehicle Engineering Tests

This report presents the results of a series of engineering tests carried out on the Washington Metropolitan Area Transit Authority (WMATA) rapid transit cars from September 1976 to August 1977, at the Department of Transportation (DOT), Transportation Test Center (TTC), Pueblo, Colorado. The test...

VSS Demonstration Program: Part 2 - Model Development and Analysis

The Vertical Shaker System (VSS) was the initial test program conducted at the Rail Dynamics Laboratory. The objectives of this program were to demonstrate the performance and capabilities of the VSS and to accumulate test data to be used in checking the validity of analytical models. The...

Users' Manual for Program for Calculation of Kalker's Linear Creep Coeffecients

A program written in FORTRAN IV is described that uses the Hertz theory of rolling contact between two bodies and Kalker's linearized theory of creep to determine the geometry of the contact patch between railway vehicle wheel and rail and the creep coefficients that characterize the linearized...

User's Guide to Fatigue Life Analysis Program (FLAP)

This guide documents the use of the Fatigue Life Analysis Program which is intended for use in the implementation of the Interim AAR Guidelines for Fatigue Analysis of Freight Cars. This computer program is a tool by means of which the freight car design engineer can readily incorporate fatigue...

Use of Linear Motors for Conventional Railroad Applications

This paper discusses the various possible uses of linear electric motors in railroads under particular operating conditions found in the United States. Performance characteristics of some linear motor designs are presented first to provide an illustration of the range of performance that can be...
