Special rail routing of spent fuel shipments from commercial nuclear power plants away-From-Reactor (AFR) storage and disposal sites has been proposed as one means of reducing the consequences and severity of radioactive materials accidents in areas of high population density. Whether or not...
This report contains engineering parameter descriptions of major and distinctive freight vehicle configurations covering approximately 96% of the U.S. freight vehicle fleet. This data has been developed primarily for use in analytical simulation modeling of rail vehicles to analyses of vehicle/...
The National Bureau of Standards correlated the mechanical properties and metallurgical
characteristics of two steel head plate samples taken from tank cars subjected
to switchyard impact tests. This metallurgical evaluation included determining
whether the samples conformed with the appropriate...
The sample was taken from the A-head plate of tank car SOEX 3033 involved in an accident
near Winder, Georgia. The A-head plate was reportedly produced to specification ASTM
A212-65, Grade B steel. The results of laboratory check chemical analyses indicated that
the plate sample met the chemical...
The FRA's Research and Development program has as its
goals near-term improvements in products and processes which
would enhance safety, improvements in the economic viability
and efficiency of the Nation's railroad operations, and reduction
of adverse environmental effects of railroad...
This report presents the results and findings from a study titled “Needs Assessment—Railroad Test Track (RTT) Siding Options for High Speed Testing.” This study was conducted to (1) determine potential capabilities that the proposed siding test track for the Transportation Technology Center, Inc. (...
The Computer Vision Laboratory at the University of Maryland has completed a two-year research project in which it developed a library of tools and algorithms that are used to inspect railway tracks with machine vision technology. This technology has been integrated into a distributed computing...
A procedure for the selection of rail passenger truck design
parameters to meet dynamic performance indices has been developed. The
procedure is based upon partitioning the design task into three trade-off studies: (1) a vertical ride quality-secondary stroke trade-off,
(2) a lateral ride...
This report discusses the venting of vapors from rail tank cars. Two particular
problem areas are addressed, namely the non-steady character of the flow in
the final blow-down stage and the influence of real gas effects on flow predictions.
Equations are developed with which the non-steady mass...
This volume contains some of the more detailed data and analyses to support the
results and conclusions reached in Volume I of this report. It is divided into
appendixes lettered A through J.
Appendix A defines a procedure for evaluating the statistical parameters from
field-collected track-...
