DYNALIST, a computer program that extracts complex eigenvalues and eigenvectors for dynamic systems described in terms of matrix equations of motion, has been acquired and made operational at TSC. In this report, simple dynamic systems are used to define the DYNALIST terminology. Input...
The information in this report covers the procurement, development and testing of instrumentation designed to measure the dynamic forces and temperatures which are created in the wheels of a loaded rail vehicle truck. The information contained herein is intended for use by scientific, research...
This report summarizes a comprehensive study of potential means of reducing the probability of train-train collisions through enhancement of the visual conspicuity of the trailing end of trains. The basic function requirements and constraints for such devices are set forth, followed by a review...
This annual report by the Secretary of Transportation serves as an information source for those having a technological interest in FRA's research, development and demonstration activities. It covers not only programs funded by the High Speed Ground Transportation Act of 1965, but also related...
This reference manual on lateral force characteristics of various types of draft gears and couplers under draft and buff loads during angling was developed as part of the Track-Train Dynamics Program. Data from these tests can be used in several TTD mathematical models, particularly the Lateral...
The development of techniques and criteria for track design is an important part of the Rail Supporting Technology Program that is being managed for the Urban Mass Transportation Administration by the Transportation Systems Center (TSC). This report presents the results of a critical review of...
