Digging Into Cause Codes for Track-Related Derailments
by Jeff Tuzik Derailments have many causes. Some are fairly simple and straightforward, others involve a complex combination of factors and circumstances. Determining the root causes is what keeps derailment investigators busy, and what helps railroads avoid such derailments in the future. Over the years, and over the course of …
Assessing the Findings of a Derailment Investigation: Was the Right Cause Found?
by Jeff Tuzik The Great Dismal Swamp. An ominous name. And in June of 2019, it was the site of a Norfolk Southern derailment. At NS, all derailments are investigated to determine the cause(s) and to provide data that could help prevent future incidents. Brad Kerchof, formerly Director of Research …
Examining the Role of Wheel/Rail Interaction in a Unit Train Derailment
George Fowler, a veteran investigator, analyzed the 2016 Grey derailment involving a Canadian National train, highlighting that derailments often stem from combined vehicle and track factors. His investigation revealed issues like track geometry, maintenance, and vehicle dynamics, emphasizing the importance of thorough evaluations to prevent such incidents in the future.
Using Digital Twin Simulations of Automated In-Train & Vehicle/Track Dynamics to Reduce Derailment Risks
Cory Hogan, Director of Vehicle Dynamics at Ensco Rail, highlights the use of digital twins in predicting rail system issues before they occur. Ensco employs advanced simulations and data collection to model vehicle dynamics, enhance safety, and streamline railroad operations, aiming to develop increasingly sophisticated and accurate digital twins for rail networks.
