Steel Alloys with Lower Bainite Microstructures for Use in Railroad Cars and Track

In-line hardening of railroad rails to produce a very fine pearlite microstructure has become a commercial reality. A question that this report seeks to answer is whether or not it is possible to find an alloy composition that will permit the development of lower bainite microstructures by in-line...

Evaluation of Semi-Empirical Analyses for Railroad Tank Car Puncture Velocity, Part II: Correlations with Engineering Analyses

This report is the second in a series focusing on methods to determine the puncture velocity of railroad tank car shells. In this context, puncture velocity refers to the impact velocity at which a coupler will completely pierce the shell and puncture the tank. In the first report in this series...

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...
