Determinations of Dynamic Fracture Toughness Properties of Rail Steels

Motivated by the occurrence of a long-running rail web fracture in service, dynamic fracture mechanics research was undertaken to (1) quantify the crack driving force due to the residual stresses induced by roller straightening operations, (2) determine dynamic fracture toughness values for rail...

Classification of Hazardous Materials in Rail Transportation

The regulations pertaining to the classification of hazardous materials in rail transportation were examined for their robustness in identifying hazards, the classification of hazardous materials, and the utility of these classifications to those who must deal with rail accidents involving...

Characterization of Residual Stress and Texture in Cast Steel Railroad Wheels

Residual stress and texture were characterized in the rim of a cast steel railroad wheel, using both an electromagnetic-acoustic transducer (EMAT) and a piezoelectric transducer. Orthogonally polarized shear-horizontal waves were propagated through the thickness of the rim, and arrival times...

Certain Railroad Employee Fatalities Investigated by the Federal Railroad Administration: Calendar Year 1985

[From the Introduction] This report presents the Federal Railroad Administration's findings in its investigation of 36 railroad employee fatalities suffered during 1985. Not included are the employee fatalities that occurred as a result of train derailments, collisions, or rail-highway crossing...

Accident/Incident Bulletin No. 155: Calendar Year 1986

[From the Introduction] Railroads are required to file monthly accident/incident reports with the Federal Railroad Administration's (FRA) Office of Safety in accordance with 49 CFR 225. Bulletin 155 summarizes reportable accidents/incidents that occurred in the United States during 1986.

Ultrasonic Inspection of Railroad Rails by Electromagnetic Acoustic Transducers (EMATs)

EMATs offer unique characteristics that appear to be advantageous for inspection of railroad rails. These characteristics include the features that EMATs do not require a liquid couplant or physical contact with the object being tested, they can generate ultrasonic wave modes that cannot be...

The Feasibility of a Nationwide Network for Longer Combination Vehicles

The truck productivity improvements derived from the 1982 Surface Transportation Assistance Act (STAA'82) and the possible introduction of a Longer Combination Vehicle (LCV) network will have a negative impact on the U.S. railroad industry, trucking's primary competitor. This report presents the...

Report Number 13 - Examination of Failed Railroad Car Wheel/Axle Assembly from Derailed Passenger Car, McIntosh, Georgia

At the Request of the Federal Railroad Administration, the National Bureau of Standards conducted an examination of a failed wheel assembly from an Amtrak passenger car involved in a derailment at McIntosh, Georgia. The west lead wheel of the trailing truck of the car was found to have a radial...

Monitoring Devices for Railroad Emergency Response Team

This report examines new devices and technologies either commercially available or being developed which might have application to the railroad hazardous material spill response problem. Procedure and monitoring device information from Southern Railway, U.S. Coast Guard, Environmental Protection...
