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 customerservice@cbizmedia.com.

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.

  1. Prior to entering into any arrangement to acquire private-marked equipment, customers must discuss the opportunity with their UP representative.
  2. 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.
  3. 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.
  4. UP may, at any time, require customers to store their private cars or move them offline at the customer's expense.
  5. 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).
  6. 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.
  7. 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)

  1. Prior to entering into any arrangement to acquire foreign marked equipment, discuss the opportunity with your UP representative.
  2. 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.
  3. If the cars have the railroad's marketings, request for their assignment should be under the provisions of Car Service Rule 16. Make that request via your UP Car Management Representative.
  4. See additional information on Car Service Rule 16.

3. OT-5 Registration

Mechanical Requirements

  1. Cars must comply with and be maintained, by the owner, per the AAR Office Manual and all AAR Field Manual Rules.  All AAR Field Manual Rules, Sections A.1 and A.2 defects and obsolete/prohibited components, must be repaired or replaced prior to placement of the cars on the Railroad.
  2. Greater than 268,000 Pound Gross Rail Load Freight Cars of any Car Type must meet the following:

The sealing member must be maintained in good condition and not allow product to bypass the seals and leak onto the ground.  All gates must be of a positive lock design, with security seal capability. 
  5. Union Pacific Mechanical Department Contacts

Engineering Requirements

System guidelines for car length and allowable GWR (gross weight on rail) that Union Pacific will use for traffic on lines that are rated at 134 tons (268K) (including all or portions of the Springfield, Joliet, Hiawatha, Angleton, Brownsville, and Nogales Subs, plus myriad minor subdivisions and industrial leads).
    1. 48'-8" or longer: maximum 134 ton (268K) GWR and as governed by Mechanical standards
    2. 44'-11½" or longer but less than 48'-8": maximum 123 ton (246K) GWR
