Loading Authority (OT-5)

The Loading Authority (OT-5) system provides a centralized, paperless process for submitting and approving OT-5 applications. It facilitates the potential placement of private freight equipment at specified loading locations on a railroad.

For rail equipment to be approved for potential loading, submit an OT-5 application to the linehaul carrier for the loading location, as specified in the Association of American Railroads' OT-5 Circular, effective since 2009. Railroads must approve OT-5 applications before private railcars can be placed in service on the North American rail network. 

The controlling entity (railcar owner or lessee) or its representative is responsible for submitting an OT-5 application. The application is submitted to the relevant Class I railroad, which reviews and approves or rejects the application within 45 days.
