Force Environment Evaluation of Stub Sills on Tank Cars Using Autonomous Over-the-Road Testing of the Instrumented Tank Car
Keywords: Tank cars, stub sills, ENSCO, track geometry, measurement, load environment, operating conditions, instrumented tank cars, data collection, vertical coupler force, longitudinal coupler force
Abstract: Fractures have been observed on stub sill tank cars for many years. Undetected and unattended, these fractures can develop into a variety of tank car failures. While tank car...
Keywords: Risk Evaluation Framework and Selected Metrics for Tank Cars Carrying Hazardous Materials; Risk evaluation; tank car; toxic by inhalation; poisonous by inhalation; hazardous materials
Abstract: This report presents an analysis of train accident and hazmat release data to quantify the likelihood of a hazmat release. The harm caused by a hazmat release is characterized as...
