This 2024 report summarize progress made in upgrading North American rail tank cars transporting Class 3 flammable liquids to the DOT-117 standards. The new DOT-117 standards, finalized in 2015, specify the design characteristics of DOT-117 and DOT-117R (retrofitted) tank cars. These characteristics include a thicker, insulated/thermally protected tank;1 a full height head shield; and top and bottom valve fitting protections.
All tank cars in service in 2023 that were subject to FAST Act rules regarding the transport of Class 3 flammable liquids were compliant with the scheduled phase-out deadlines. Sixty-seven percent of all rail tank cars carrying Class 3 flammable liquids were built to the new DOT-117 specification or modified to meet the DOT-117R (retrofit) specification.
