NTSB Urges Quicker Phase-Out of Hazardous Material Tank Cars Following North Dakota Derailment

The National Transportation Safety Board (NTSB) has intensified its call for the accelerated removal of DOT-111 tank cars from service, following an alarming incident involving a freight train derailment in Bordulac, North Dakota in 2024. In this incident, a total of 29 railcars derailed, out of which 17 were hazardous materials tank cars, leading to the release of methanol—a flammable substance—and anhydrous ammonia, a hazardous gas. This kind of event reiterates the long-standing concerns regarding the design and safety of older tank cars, which may no longer meet the stringent demands of modern transporting standards for hazardous materials. The NTSB's renewed recommendations highlight the critical necessity of transitioning away from outdated car models to enhance public safety and environmental protection.

The investigation revealed that the incident was precipitated by a broken rail, which was likely caused by a degraded culvert. The precarious integrity of the railroad infrastructure raises alarms regarding not just the cars themselves, but also the overall safety standards that govern rail lines that transport dangerous materials. The NTSB's emphasis on better inspection protocols for rail infrastructure indicates potential procurement opportunities for companies specializing in rail safety technologies, inspection services, and infrastructure improvements. There exists an increasing need for innovative solutions that can secure more rigorous oversight and compliance with safety standards, particularly following high-profile incidents.

Importantly, the NTSB has raised serious doubts around the retrofit design of DOT-117R tank cars, which are modified versions of the DOT-111 cars; the modifications have not shown significant safety improvements. The report indicates that while DOT-117R cars were expected to address some safety shortcomings associated with their predecessors, they still fall short of providing adequate protection against puncture during derailment incidents. This reinforces the NTSB's argument for a rapid phase-out of both models in favor of newly constructed DOT-117J tank cars, which adhere to stricter safety specifications. For contractors engaged in the design and manufacturing of rail tank cars, this presents an urgent market opportunity to innovate and produce compliant vehicles that align with the latest federal safety mandates.

Additionally, the implications for procurement professionals are substantial. As federal agencies such as the Pipeline and Hazardous Materials Safety Administration (PHMSA) and the Federal Railroad Administration (FRA) begin to raise their requirements for hazardous materials transportation safety, contractors must prepare for forthcoming solicitations that will focus on improved designs, materials, and inspection services. There will likely be increased demand for both advanced designs of tank cars and inspection technologies to ensure compliance with emerging safety benchmarks, especially in regions previously affected by incidents similar to the one in North Dakota.

As the regulatory landscape evolves, it will be essential for stakeholders in the rail transport sector to stay proactive and vigilant regarding these developments to secure contracts and partnerships that will support these necessary improvements in the transportation of hazardous materials. This also underscores the critical role that state and local governments, alongside industry partners, will play in enforcing and adhering to enhanced safety standards moving forward.
