The primary purpose of, the tests documented herein was to demonstrate the principles and feasibility of an energy-storage-type propulsion system, and its adaptability to an existing car design. The test program comprised four phases of tests on two New York City Transit Authority R-32 cars where...

Engineering Tests for Energy Storage Cars at the Transportation Test Center: Volume I - Program Description and Test Summary

Development of a System to Display and Record Slack Action in Freight Trains

This report summarizes the development of a system which senses, displays and records the slack action or inter-car movement in freight trains. The system, called the Draft-Buff Indicator (DBI) , was developed to serve as a train-handling aid. It provides the user (railroad training officer,...

Calculated Performance of the ASEA RC4A and Alsthom CC14500 Locomotive Hauled Amfleet Consists - New York to Washington, D. C.

This report presents a description and the results of Train Performance Calculations performed to determine the performance of specific Swedish and French Locomotive Hauled Amfleet Consists on the existing Northeast Corridor track route between New York City and Washington, D. C., assuming a...

An Analytical and Experimental Evaluation of Concrete Cross Tie and Fastener Loads

This report has been prepared as part of the Improved Track Structures Research Program sponsored by the Office of Rail Safety Research of the Federal Railroad Administration. The report covers a review and evaluation of track analysis models for predicting tie and fastener loads. The principal...

A Study on Railroad Ballast Economics

This report presents the results of Phase V - Economic Evaluation of the Ballast and Foundation Materials Research Program. The present "State of the Art" in the ballast costing area is discussed. The individual ballast costs are quantified to the extent possible using the data base compiled...

A Bibliography on Rail Technology

This rail technology review provides assistance to a number of rail technology programs initiated by the Transportation Systems Center (TSC) for the Federal Railroad Administration (FRA). The results of a search and review in four specific areas in the field of rail technology are presented in...

Tank Car Head Puncture Mechanisms

In a number of railroad accidents the shell heads of hazardous material tank cars have been punctured. This report is concerned with the description and analysis of head puncture mechanisms. Three classification yard accidents and one main line accident were studied in detail, train-to-train...

Study of Friction and Creep Between Steel Wheels and Rails

A systematic experimental, parametric and similitude investigation of the friction and creep behavior of a steel wheel rolling on a steel rail is given. Laboratory investigation was performed on the l/5th scale experimental GM-IIT Wheel Rail Simulation Testing Facility reported on earlier....
