Section 7308(c) of the Fixing America’s Surface Transportation Act (Pub. L. 114-94; the “FAST Act”) requires the Department of Transportation (DOT) to conduct a survey of tank car facilities to obtain an estimate of tank cars projected to be modified or built to the new safer DOT Specification 117 or 117R.  This data collection informs DOT, Congress and other interested stakeholders on the progress of upgrading the nation’s fleet of rail cars that carry hazardous materials Class 3 flammable liquids.  BTS conducted its first Annual Tank Car Facility Survey in 2018.
