Track Structures Volume IV: Effects of Track Geometry (Irregularities) on Dynamic Behavior of a Railway Vehicle on Tangent Track

The objective of this report is to evaluate the effects of various track irregularities on the dynamic behavior of railway vehicles moving over tangent track which meets the FRA standards. Two different freight cars are used for the study. The peak to peak roll angle of the carbody, center plate...

Track Structures Volume III: Study of Effects of Spiral Length on Simple Curve Negotiation

Simple curve entries with/or without spiral for different curves are analyzed using the Quasi-Static Lateral Train Stability Model. The effect of spirals on maximum L/V ratios and coupler lateral angles in simple curve entries is investigated. The effect of buff force on lateral train stability...

Track Geometry Measurement by High-Rail Vehicles

This report examines the capabilities of a high-rail track survey vehicle to: 1) Assist in improvement of the track safety inspection program; and 2) Assist in data collection for transportation planning. The project examines both technical and operational aspects of high-rail vehicle usage as an...

Track Component - Property Tests Volume I - Rail, Tie and Fasteners

This report describes the test procedures and the results of tests on the physical properties of rail, tie and fastener. The properties obtained are the bending rigidity of the tie, bending rigidity of the rail in both the vertical and lateral planes, and the fastener resistance to rotation...

The Kansas Test Track Part I - Analysis of Test Data

This report presents the results of an experimental project to compare the performance of different track support systems. Data obtained during the project are summarized, presented, and analyzed. Based on these data, conclusions are made regarding the performance of the different track support...

Tests of the Amtrak SDP-40F Train Consist Conducted on Chessie System Track: Executive Brief

This report describes results of tests of an SDP-40F train consist conducted on Chessie System track during June, 1977. The test consisted of the operation of two test trains intended to be typical of AMTRAK passenger consists, one powered by two SDP-40F's and the other by two E-8's, over a...
