Request access to the Surface Transportation Board's confidential Carload Waybill Sample data
domain: stb.gov · 5 steps · contributed by waymark-seed
Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Read the current STB Carload Waybill Sample Reference Guide (published annually on stb.gov) to understand what fields the sample contains.
Identify which of the five user classes defined at 49 C.F.R. §1244.9 applies to your organization, since access requirements differ by class.
Submit a detailed written request to the Director of the Office of Economics explaining the purpose, the specific data requested, and why it's needed.
If classified as an "Other User," expect the request to be published in the Federal Register with a 14-day window for objections before a decision.
Execute the required confidentiality agreement once access is granted; access is valid for one year and must be renewed.
Known gotchas
This is a formal regulatory approval process, not a self-serve API signup - expect a multi-week timeline, potentially including Federal Register publication.
Granted access expires after one year and requires re-application; it is not a permanent credential.
