Evaluation of Semi-Empirical Analyses for Railroad Tank Car Puncture Velocity, Part I: Correlations with Experimental Data
This report is the first in a two-part series that focuses on methodologies to determine the puncture velocity of tank car shells. In this context, puncture velocity refers to the impact velocity at which a coupler will puncture the tank. In this report, the methodology to calculate puncture...Damage Assessment of Tank Cars Involved in Accidents: Phase II - Modeling and Validation
The Accident Damage Assessment Guidelines used to make decisions on the safety of damage pressure tank cars were formulated in the 1970s by the Association of American Railroads (AAR) under the auspices of the Federal Railroad Administration. Although these Guidelines have served their purpose,...Tank Car Relief Valve Requirement for Liquid Posison Inhalation Hazard (PIH) Lading
Analyses were performed for the Federal Railroad Administration (FRA) by Transportation Technology Center, Inc., a subsidiary of the Association of American Railroads, to determine if the changes made to Chapter 49 of the Code of Federal Regulations under docket HM-181 for the selection pressure...Driver Behavior Analysis at Highway-Rail Grade Crossings using Field Operational Test Data – Heavy Trucks
Researchers examined behaviors of heavy vehicle drivers at grade crossings, such as engaging in non-driving tasks and failing to look both ways before crossing.
Due to our recent website upgrade some of the links in legacy documents might point to the decommissioned site location....
