U. S. energy supply issues for the next few decades are summarized with a view toward their impact on high speed ground transportation (HSGT) modes. As background, the energy characteristics of intercity passenger modes, including 300 mph tracked levitated vehicle (TLV) systems, are presented...
This report reviews proposed specifications and shipper regulations for 113 series tank cars for transporting liquid ethylene at cryogenic temperatures. The study was limited in scope and was to be directed primarily at the holding time requirements necessary for safe shipment of the commodity....
This publication contains 1,647 abstracts of journal articles and research reports selected by RRIS from current railroad literature and 160 summaries of ongoing research activities in the railroad field. The material covers the entire range of railroading from technology to operations,...
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...
