Excess oversized loads are described as any load on a railcar exceeding 17 feet above the top of rail and/or 11 feet wide. Additionally, loads that overhang the end sills of the railcar are classified as oversized loads. Easy access to our weight restriction maps lets you know if your shipment is of excessive weight while on BNSF. Shipments exceeding provided parameters are subject to operating schedules and windows and therefore subject to delays not otherwise affecting normal carload shipments.
The process begins with the shipper following the step by step guide for shipping oversized loads. See oversized shipments to view this process.
The shipper must receive clearance, obtain rates and request cars from the originating railroad. In the case of a load originating on a shortline railroad, the first linehaul or roadhaul carrier should be contacted.
Complete the Oversized Clearance Request Form, by logging into our website. For instructions on how to register on our website or access the form, see oversized shipments.
The BNSF Clearance Department reviews the submitted information. Once a determination is made, the customer will be notified via e-mail.
Obtaining approval for physical clearance DOES NOT constitute operational clearance or authority for the shipment described in the clearance request to move on the BNSF network. Once physical clearance has been obtained, your shipment must be submitted for operational and risk management approval. Contact your marketing representative for more information prior to initiating loading or movement.
An idler is an empty car placed between your shipment and the next load. Idlers are required for shipments that overhang the end sills for the railcar and/or are of excessive weight as determined by BNSF's Engineering Department. Idlers can be requested when requesting the heavy-duty flatcar.
The Clearance Department will make this determination based on the characteristics of the load as submitted in the Oversized Clearance Request Form. This information will be included in the proposal response from BNSF's Clearance Department.
The shipper is responsible for loading, tie-down and securement of shipments to the railcar. BNSF Mechanical offices can provide requirements or a copy of the Open Top Loading Manual can be purchased from the Association of American Railroads (AAR). Please see the contact page for contact information.
All loaded oversize shipments must receive securement inspection and measurements prior to shipment from the originating rail carrier. Please see Step 5 - Receive Inspection (links to Shipping tab and to the “Get Inspected (2 days before shipment” section) for contact information.
