Loading Authority OT-57 replaces Loading Authority OT-5.  OT-5 is retired effective January 2, 2020.

The Loading Authority OT-57 system provides a centralized, paperless process for registering private freight rail equipment and access to controlling entity (shipper, owner, or lessee) contact information and storage information. It facilitates the potential placement of private freight rail equipment at specified storage locations on a railroad.

Refer to the following notifications for information about the Loading Authority (OT-57) system:

For private rail equipment to be entered into loaded revenue service, private rail cars should be registered in the Loading Authority OT-57 system, as specified in the Association of American Railroads' OT-57 Circular, effective since 2020.

The controlling entity (railcar owner or lessee) or its representative is responsible for registering cars within the Loading Authority OT-57 system.
