Freight Car Fatigue Test on FAST

As a result of observed cracks in the fabricated center sills of many freight cars in the FAST consist, a special Fatigue Analysis Test (FAT) was conducted on the FAST Track during August and September of 1978. This report provides an analysis of the static and dynamic strain data from a base case...

Evaluation of the Costs and Benefits of Advanced Braking and Coupling Systems

This report presents an evaluation of the costs and benefits of sixteen advanced railroad braking and coupling systems. Most of the benefits result from improved classification yard efficiencies, with secondary benefits accruing through reduced accident rates, road delays, and maintenance related...

Evaluation of Signal/Control System Equipment and Technology: Task 5 - Economic Studies

Economics form an important aspect in the comparison of new technologies with those which are subject to possible replacement. This report presents an economic analysis of candidate state-of-the-art signal/control systems which were selected in preceding tasks of the project. The report focuses on...

Dynamic Hopper Car Test

This report describes a test designed to establish the relationship between ride performance and track degradation, vehicle component wear, and the combined effect of rail degradation and component wear. The test was also designed to quantify the dynamic response of freight vehicles to different...

Draft Gear/Cushioning Unit Optimization for Train Action - Volume II: Final Report

This report describes a series of impact tests that were conducted by W. H. Miner, Inc., Research and Development Division, for the Draft Gear/Cushioning Unit Optimization Task of Track-Train Dynamics - Phase II. Using a special test fixture car, modified for these tests, buff and draft impact...

Design of Dead-Wire Instrumentation Package for Use on Electrified Railroad Test Track at Transportation Test Center

This report describes an instrumentation package designed to perform geometry measurements on a catenary system and to identify areas requiring adjustment, to perform maintenance checks on the catenary, to determine long-range stability and to provide performance data on a variety of pantograph/...

Design Feasibility Study for Modifying an Existing Heavy Rapid Rail Truck to a Steerable Configuration

[From the Executive Summary] The objective of this program is to determine the feasibility of modifying an existing urban rail vehicle truck to a steerable configuration for the purpose of improved curving performance. The anticipated benefits from the use of steerable trucks on urban transit...

Concrete and Wood Tie Track Performance through 150 Million Gross Tons

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 presents an evaluation of concrete and wood tie track performance from test data taken at the. Facility for...

Comparisons Between Designs for Single-sided Linear Electric Motors: Homopolar Synchronous and Induction

A design study of two types of single-sided (with a passive rail) linear electric machine designs, namely homopolar linear synchronous machines (LSM's) and linear induction machines (LIM's), is described. It is assumed the machines provide tractive effort for several types of light rail vehicles...

Assessment of Locomotive Crew In-Cab Occupational Noise Exposure

The railroad industry, unlike most other U.S. industries, is not subject to the safety regulations of the Occupational Safety and Health Administration. Instead, railroad workers are covered by the safety regulations of the Federal Railroad Administration (FRA). This report documents an extensive...
