Before scheduling an oversized shipment, please read the following guidelines:

Clear It

For shipments that are oversized, your clearance request lets us officially initiate the process to confirm that our infrastructure can handle your load. To submit your clearance request, log in to BNSF.com, go to the PLAN tab, and select Oversized Clearance Request. We evaluate primary and secondary routes and let you know your best shipping option. You'll also receive a proposal number that you'll need through the rest of the process. Each request includes a $1,000 fee (to be increased to $2000 on January 1, 2025), which is refundable on all proposals that become actual loads on BNSF, within one year. Read more about the Pay-for-Proposal fee refund.

Note: Clearance requests must be submitted to the originating rail carrier. To submit your clearance request, you will need to establish your loading and unloading sites, then log in to BNSF.com.

Request Cars (4 weeks before shipment)

The next step is to request the railcars you'll need. Log in to BNSF.com and select the PLAN tab. To request a heavy-duty railcar, select Oversized Equipment Request Form. You'll need your proposal number and the railcar series or equipment car initial and number. To request a standard machinery flatcar, select the Railcar Equipment Request Form.

Note: Availability of railcars is subject to current supply conditions, so please allow 4 weeks for delivery.

Load It (5 days before shipment)

Next, you'll need to load and secure your railcar according to the Association of American Railroads (AAR) Open Top Loading Rules. Contained within the AAR rules are specific diagrams for loading configurations, as well as the general rules that you must follow. To obtain a copy of the AAR Open Top Loading Rules Manual, visit the Transportation Technology Center, Inc. website, call 800-544-RAIL or e-mail [email protected].

Note: It is the shipper's responsibility to correctly load and secure the load.

Submit Instructions (2 days before shipment)

Proper shipping instructions are essential for BNSF to provide the correct transportation services and invoice at the appropriate rate. To submit your shipping instructions, log in to BNSF.com and select the SHIP tab. You'll need the appropriate rate authority. For oversized loads, you'll also need your proposal number, and you'll need to select a special handling condition of "Extreme Dimension."

Note: You can also submit shipping instructions via EDI, through voice activation by calling 1-888-428-2673, or through the rail industry website www.steelroads.com.

Get Inspected (2 days before shipment)

All loaded oversized shipments must be approved before the shipment can receive final clearance and be moved. For shipments with an eight or more axle railcar, contact BNSF Inspections; for shipments with less than an eight-axle railcar, contact a BNSF mechanical foreman.

Not Rail Served?

• If you are not directly served by a railroad and need delivery by truck, consider using a transloader or a BNSF team track.
• You can also work with our Economic Development team to establish or expand your next site. Talk to us today!

Private Equipment Guidelines

The following section contains guidelines and information for the use of privately marked equipment where BNSF is the origination line-haul carrier.

1. Private rail equipment must meet the Association of American Railroads' (AAR's) Circular OT-5 for Rules Governing the Assignment of Reporting Marks and Mechanical Designations. Privately marked equipment must also be registered via the OT-57 process that is administered by Railinc. For more information, please visit Railinc's Loading Authority (OT-57) web site.
2. Private equipment controlling entities are required to manage the flow (pipeline) of empty equipment moving to BNSF origin line haul locations or connecting carrier serving locations to preserve network fluidity.
   
3. BNSF may require private equipment controlling entities to move equipment off-line at their expense to preserve network fluidity.
   
4. Private equipment is subject to charges for both equipment held for loading and unloading and equipment held for purposes other than loading or unloading.
   
5. BNSF's Mechanical Requirements for Private Equipment listed below.
   

SAFETY IS BNSF'S MAIN PRIORITY

The following is not all inclusive. However, equipment must comply with all of the following key mechanical requirements:

1. All interchange freight car owners must subscribe to the AAR Interchange Rules and be listed in FindUs.Rail.
2. Cars must comply with and be maintained, by the owner, per the AAR Office and Field Manual Rules.
3. All AAR Field Manual Rules (Sections A.1 and A.2 defects along with any component obsolete or prohibited in interchange) must be complied with and equipment must be repaired or replaced prior to placement of the cars on BNSF.
4. All cars must have yellow Federal Railroad Administration (FRA) 224 compliant reflectorization with the application date registered in Umler (no grandfathered material allowed).
5. Angle cocks located below the coupler as shown in AAR Field Manual Rule 5 Figure 14 are prohibited.
6. Greater than 268,000 Pound Gross Rail Load Freight Cars of any car type must meet one of the following criteria:

1. Cars are approved by the AAR per Specification S-286 or
2. Cars are approved by the AAR per Specification S-259 and the following is met: Cars must be equipped with constant contact side bearings, preferably long travel.
3. Cars must be registered with the proper Star Code.

7. 286,000 Pound Gross Rail Load Freight Cars of any car type less than 44 feet 11 inches in overall length must have route specifically approved by BNSF due to bridge loading concerns. The following link can assist in route selections: Rail Network Maps.
8. Flat Cars of any type and capacity must be equipped with constant contact side bearings. Long travel constant contact side bearings are preferred.
9. Covered Hoppers must have outlet gates that seal completely. The sealing member must be maintained in good condition and not allow product to bypass the gaskets/seals and leak onto the ground. All gates must be of a positive lock design with security seal capability.
10. Cars equipped with one or more rotary couplers must be equipped with anti-gravity locks on both ends.
11. All Cars must meet AAR and FRA Safety Appliance Standards.
12. Gondolas and bulkhead flat cars must be equipped with crossover platform and associated safety appliances on both ends.
13. Bottom dump coal hopper cars equipped with door line air hose must have this hose in the "low" configuration as to not block the crossover platform.
14. Tank cars must be equipped with a Group R "weather resistant" slack adjuster.

Foreign Marked Equipment Guidelines

Foreign marked equipment is defined as equipment having reporting marks of a non-BNSF controlled railroad or equipment that contains non-private marks. Private marks are defined as equipment initials ending with an X, with the exception of TTX owned/controlled equipment.

• Request for assignment of foreign marked equipment should be in accordance with Car Service Rule 16. Requests should be made through your BNSF representative.
• BNSF reserves the right not to use foreign marked equipment when BNSF-controlled equipment is available. If no agreement exists with customers/controlling entities to utilize foreign marked cars, BNSF may refuse to place non-BNSF marked equipment for loading and may return them to the railroad whose marks are stenciled on the cars.
• Prior to securing foreign marked equipment to be loaded at a location where BNSF is the origin line haul carrier, customers/controlling entities must discuss equipment options with their BNSF sales representative.

Loading Origin Guarantees

Shippers have the ability to guarantee equipment supply through BNSF's Loading Origins Guarantee (LOGs) program. Log in to our Customer Portal to find more information.

Heavy Duty Car

To reserve a heavy duty car, contact TTX or Kasgro prior to making arrangements for shipment of freight.
