Reminder: Complying with AAR Loading Rules

Jul 18, 2019

With BNSF's commitment to keeping shipments fluid and safe, customers are required to comply with the AAR loading figures contained in the AAR Open Top Loading Rules Manual. Shippers may view these requirements at the following links:

BNSF can provide contact information for load adjustment contractors who have been instructed in the AAR Open Top Loading Rules and who carry the mandatory insurance to work on BNSF property.

As a reminder, any incident caused by shipper failure to follow these rules will result in the shipper being responsible for making the necessary arrangements to correct the loading deficiencies. The shipper will also be financially responsible for the incident's associated costs.

We encourage customers to review The Association of American Railroads (AAR) Open Top Loading Rules Manual to ensure compliance with BNSF's loading rules. AAR now offers a free online library to select and download various sections of the manual as well as individual rule documents and implemented circular letters: Click here to access.
