Private and Foreign Marked Car Policies
The following information outline policies concerning private- and foreign-marked equipment used when UP is the originating carrier. These policies follow the Official Railway Equipment Register and AAR Interchange Rules. Information for ordering a copy is available from 1-888-215-6084 or firstname.lastname@example.org.
Requests to Supply Private or Foreign Marked Equipment
1. Private Equipment
Under AAR Circular OT-5, prior to loading private cars, approval must be obtained from the origin line haul carrier using the Railinc OT-5 registration system. After the application is approved by the carrier, cars can be used by the car controller for loads originating at specified stations and industries.
- Prior to entering into any arrangement to acquire private-marked equipment, customers must discuss the opportunity with their UP representative.
- The car controller must submit an OT-5 application to the originating carrier via the Railinc OT-5 registration system requesting approval for shipper-provided cars prior to the cars being moved online. Pre-approval can be obtained in the same manner.
- UP has the right to deny the OT-5 application for safety, mechanical factors or inadequate customer storage space. Please see step g of this section for full policy.
- UP may, at any time, require customers to store their private cars or move them offline at the customer's expense.
- If private marked cars have a load capacity of 286,000 pounds Gross Weight on Rail (GWR), they must be equipped with constant contact side bearings and up-to-date on scheduled maintance (see Mechanical and Engineering Requirements below).
- Termination of loading authority on UP may occur at any time under the following circumstances: guidance of the AAR Interchange Rules, expiration date of lease, age out, inadequate storage, mechanical or safety issues.
- See additional information on OT-5's.
2. Foreign Marked Equipment (i.e. equipment bearing reporting marks of a railroad that is not controlled by UP)
- Prior to entering into any arrangement to acquire foreign marked equipment, discuss the opportunity with your UP representative.
- UP is not required to use foreign marked cars. In the absence of an agreement with a customer to use foreign marked cars, UP may refuse to place foreign marked cars for loading and may return them to the railroad whose marks appear on the cars.
- If the cars have the railroad's marks, request for their assignment should be under the provisions of Car Service Rule 16. Make that request via your Union Pacific Equipment Distribution Representative.
- See additional information on Car Service Rule 16.
