General Models for Lateral Stability Analyses of Railway Freight Vehicles

This report presents the development of general analytical models for use in exploring the nature of freight car hunting and for finding means of controlling the hunting behavior. These models result from one aspect of the "Freight Car Dynamics" research project conducted by Clemson and Arizona...

FAST Ballast and Subgrade Materials Evaluation - Ballast and Foundation Materials Research Program

The ballast, subballast, and subgrade materials from the FAST Project at Pueblo, Colorado were evaluated. Conventional characterization testing and repeated load triaxial testing were conducted with the various materials. The data included in this report were developed for bulk material samples...

Engineering Tests for Energy Storage Cars at the Transportation Test Center: Volume IV - Ride Roughness Tests

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...
