Annual Tank Car Facility Survey

OMB #: 2138-0047   Expiration Date: July 31, 2024

About us and why we are collecting this information

The Bureau of Transportation Statistics, a statistical agency within the U.S. Department of Transportation, is conducting a national survey of tank car facilities to monitor industry-wide progress in upgrading tank cars that transport Class 3 flammable liquids. This survey is authorized by Section 7308(c) of the Fixing America’s Surface Transportation Act (Pub. L. 114-94) signed into law on December 4, 2015. This legislation requires the Department of Transportation to provide estimates of the number of tank cars being built or retrofitted each year to meet the new DOT-117 or 117R specifications.

Who is included?

The 2024 Annual Tank Car Facility Survey includes businesses that are certified to build or modify tank cars. More specifically, the survey is interested in collecting information from all shops and facilities in the United States that are building or modifying tank cars to the newer DOT-117 or 117R specification. Even if your facility has not previously done this kind of work, you may still be contacted to participate. On average, the survey is estimated to take 30 minutes to complete. If you are not sure whether your facility should be included in the survey, please contact the U.S. Department of Transportation, Bureau of Transportation Statistics, at 1-800-853-1351 or by email at
