Despite safety concerns, a significant number of puncture-prone tank cars, like the DOT-111 type, remain in use across US railways. The attention to replace these car models emerged post the Lac-Mégantic tragedy, emphasizing their unsuitability for transporting hazardous liquids. A spotlight on the necessity for expedited removal of these unsafe tank cars coincided with the Norfolk Southern train derailment in East Palestine, Ohio. Federal investigators encounter industry opposition in advocating for the transition to safer tank car models, underscoring persistent safety risks and regulatory challenges in the railway sector.
