The objective of this research project was to develop a predictive risk model for the release of hazardous material transported in unit trains using data science techniques for available rail accident and traffic data. This work builds upon previous research (Bing, et al., 2015) which examined...
Fractures in the stub sills of tank cars pose a significant problem for the rail industry due to the potential for damage to the tank structure and possible release of the contents. Previous FRA research revealed that high magnitude coupling forces that occur in yard operations have the...
The Federal Railroad Administration sponsored a team from Transportation Technology Center, Inc. to conduct two investigations to improve the safety of roller bearing operations on railcars. The team conducted the research between September 2018 and April 2022 in collaboration with Burlington...
The primary objective of this research was to validate the finite element (FE) stress levels obtained during previous research through physical testing of a selected knuckle design. The validated FE model was used to investigate potential improvements in knuckle fatigue life, such as higher...
The Federal Railroad Administration contracted Transportation Technology Center, Inc. to define Interface Requirement Specification (IRS) documents for an Interoperable Train Control Automated Train Operation Support System Back Office (ITC-ATOSS BO). This project forms part of a larger...
