Crude-by-Rail Still Uses Puncture-Prone Legacy Tank Cars

The United States moves roughly 300,000 carloads of crude oil by rail each year, and a significant fraction still travels in legacy DOT-111 and CPC-1232 tank cars that the National Transportation Safety Board has warned about for over two decades. These older cars have thin steel shells, no thermal protection jackets, and outlet valves that can rip open on impact. When a train carrying these cars derails, the tanks rupture, crude oil sprays across the crash site, and fireballs erupt. The industry calls them 'bomb trains' for a reason: the 2013 Lac-Megantic disaster killed 47 people when 60 DOT-111 cars released 1.6 million gallons of Bakken crude into a Quebec town center. The human and economic toll extends far beyond the immediate explosion zone. Derailments contaminate soil and waterways along rail corridors that run through hundreds of small towns with volunteer fire departments completely unequipped to handle a crude oil inferno. Property values plummet. Evacuations displace families for weeks. The East Palestine, Ohio derailment in February 2023 (which involved hazardous chemicals, not crude, but the same car design flaws) killed 43,000 fish and animals and forced a controlled burn that released hydrogen chloride and phosgene into the air over a residential area. The retrofit timeline is the structural root cause. The DOT-117 standard, which adds a steel jacket, thermal protection, and improved valves, was finalized in 2015 with a phase-out deadline for legacy cars. But the retrofit and replacement schedule has been repeatedly extended. Tank car owners and railroads lobbied for longer timelines, arguing the fleet could not be replaced fast enough. Meanwhile, PHMSA issued a safety advisory in 2023 acknowledging that legacy DOT-111 and CPC-1232 cars remain in flammable liquid service. The newer DOT-117 cars have a perfect safety record, with zero deaths, zero serious injuries, and zero fireball events in any derailment, yet the transition remains incomplete.
