Objective Evaluation of Risk Reduction from Tank Car Design and Operations Improvements – Extended Study
This report describes a novel and objective methodology for quantifying and characterizing how changes to tank car designs or the tank car operating environment lead to reductions in risk (or reductions in puncture probabilities). The methodology captures several parameters that are relevant to...Rail Tank Car Total Containment Fire Testing
A series of seven fully-engulfing fire tests were conducted by Bundesanstalt für Materialforschung und –prüfung (BAM) personnel on one-third scale test tanks to evaluate the capacity of rail tank cars carrying hazardous caustic materials, such as sodium hydroxide (NaOH) or potassium hydroxide (KOH...Railroad Energy Intensity and Criteria Pollutant Emissions
A tiered emission factors table was developed by Argonne National Laboratory to populate its Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation (GREET®) model for pollutants emissions, as well as to calculate energy intensities for passenger and freight rail applications. The...Special Bibliography Railroad Safety Reserach
This Special Bibliography prepared from the magnetic-tape files of the Railroad Research Information Service, contains selections which were accessioned between 1973 and 1976. Although the literature which is referenced does in a few cases date back three decades, all listings are considered...Ballast Fouling Measurement Tool: Phase 1
A prototype man-portable ballast inspection instrument was developed by Earth Science Systems, LLC (ESS) at their facility for use by track inspectors based on ground penetrating radar (GPR) called the RAdar Ballast Inspection Tool (RABIT). During this study, it was determined that the RABIT...Material and Manufacturing Requirements for Freeze-Thaw Durable Concrete Railroad Ties, Appendices A Through C
