Validation of Track Geometry Input to the Vibration Test Unit (VTU) and the Endurance Capability of the VTU

This report describes a series of tests conducted at the Transportation Test Center, Pueblo, Colorado, to validate two forms of track geometry inputs to the Vibration Test Unit (VTU) in the Rail Dynamics Laboratory, capable of reproducing actual revenue track conditions. The first form consisted of...

Tank Car Damage Assessment Procedure Study

The study concerns the rupture of damaged tank cars which have been involved in railroad accidents. In this regard, a series of impact tests using the FRA/BRL Drop Hammer Facility was performed. The tests consisted of the creation of controlled damage to flat steel plates which had properties...

Strain-Life Fatigue Analysis

The strain-life approach to characterize the fatigue behavior of materials and its applications to railroad equipment design have been investigated. A logical means of accounting for local plastic strains, which are the cause of fatigue failures, has been given, and constitutive relations between...

Safety Margin Testing of a 70-Ton Boxcar with Shifting Plywood Lading: Test Results Data

Tests were performed at the Transportation Test Center, Pueblo, Colorado, in a joint Association of American Railroads (AAR) and Federal Railroad Administration (FRA) effort in the April-May-June period of 1982. AAR objectives were to perform a "pilot" test on the Vibration Test Unit (VTU) as a...

Safety Margin Testing of a 70-Ton Boxcar with Shifted Plywood Lading: Summary Results

High Performance, High Cube Covered Hopper Car Program, Base Car Dynamic Performance Tests: Volume 1 - Rock-and-Roll and Bounce

A series of dynamic performance tests were conducted on a 100-ton high cube (4750 cu. ft.) covered hopper car. This report describes the test program concerning the rock-and-roll and bounce tests, which were conducted on shimmed track sections at the Transportation Test Center in Pueblo Colorado....

Development of Hybrid Cost Functions From Engineering and Statistical Techniques: The Case of Rail - Phase II Final Report - Executive Summary

Cost analysis is important in every transportation industry, to the firms or agencies which provide service, to regulatory bodies, and to public policy makers. In the past, railroad cost analyses have been of two types: 1) statistical analyses of aggregate cross-section data from a variety of firms...
