Environmental Risk Analysis of Chemicals Transported in Railroad Tank Cars

This study assesses the risk to soil and groundwater in the event of a spill of hazardous materials transported in railroad tank cars. Tank cars are designed to be resistant to damage in accidents to reduce the probability of a spill. For safety and economic reasons, the damage-resistant design of tank cars is commensurate with the degree of hazard posed by the product they are intended to tran...

Hazard Assessment for Pressure Tank Cars involved in Accidents

In the event of an accident or derailment involving a freight train, various personnel must respond to clear the rightof-way, repair the tracks, and remove the damaged rail cars. If the train contains pressure tank cars, the potential hazard needs to be assessed and safe handling procedures need to be followed. Since 1985, the Association of American Railroads, Transportation Technology Center ...

Evaluation of Acoustic Emission Inspection of Oil Tank Floor via Tank Bottom Plates Thickness Measurement

This paper deals with an inspection of defects including corrosion and leakage by Acoustic Emission (AE) in an oil tank floor. In contrast to intrusive methods such as magnetic flux leakage, eddy current or ultrasonic, there is no need to emptying and entering the tank in AE method in order to inspection. In this research AE investigation and AE source location is presented in detail. The resul...

Evaluation and Application of Super-Tough Steel for Use in Tank Cars Transporting Cryogenic Liquids

Finite Element Analysis of Fluid-Structure Interaction in Pressurized Tank Cars Subjected To Dynamic Impact Loading

This paper presents a computational study of the fluid-structure interaction (FSI) mechanism in pressurized commodity tank cars in railroad application. Within the Lagrangian framework of Abaqus/Explicit, finite element analysis (FEA) is conducted to predict the structural response of tank cars under dynamic impact loading. A three-phase approach is adopted that explicitly models pressurized ga...
