The following section contains guidelines and information for the use of privately marked equipment in which BNSF is the origination line-haul carrier.
Private rail equipment must meet the Association of American Railroads' Circular OT-5 for Rules Governing the Assignment of Reporting Marks, Mechanical Designations, and Use. Privately marked equipment must obtain loading authority from the origin line-haul carrier and the equipment must be registered via the OT-5 process that is administered by Railinc. To register, you will need your CIF number, proper UMLER information and the car numbers to be registered. For more information, please visit Railinc's Loading Authority (OT-5) web site.
Managing evolving network and operating conditions requires BNSF to closely review all requests we receive to add new equipment to our system and determine, among other factors, what impact individual requests could have on network fluidity, capacity, service and velocity. We are also engaged in an effort to address existing non-compliance on BNSF and across the industry of the OT-5 registration process (unregistered cars).
BNSF considers multiple factors when reviewing OT-5 applications. Applications can be declined for reasons including: safety, mechanical, lack of verifiable track storage space, or a combination of resulting factors that these reasons may cause.
BNSF evaluates whether adequate storage exists by reference to the details and context of each individual OT-5 application. This includes, among other factors, the storage location(s) proposed by the applicant, the storage location entity's ability to confirm the storage capability represented on the application, the type of cars on the application and their anticipated use on the BNSF network.
BNSF will provide an explanation for all OT-5 application rejections. If an application has been declined, the application can be re-submitted after all details provided in the rejection notice have been resolved to BNSF's satisfaction. Any question concerning rejected applications should be directed to your BNSF Sales representative.
Under AAR Circular OT-5, approval MUST be obtained from the loaded origin line-haul carrier prior to loading private cars. BNSF reserves the right to address non-registered cars on an individual basis.
