Terms and Conditions

We provide this page for easy customer access and presentation. For the most comprehensive rules information for many of the documents referenced on this page, see our Price & Transit Time Inquiry, under the "Search by Documents" option. If there are any discrepancies, the version in the Price & Transit Time Inquiry supercedes what's on this page.

Accessorial Charges

The Accessorial Charges are standard rates. Union Pacific Railroad endeavors to keep the information on its website up-to-date and correct. However, the information contained in Union Pacific Railroad's official documents (tariffs/circulars/contracts/quotes) supersedes the information shown here.

Allowable Gross Weight for Rail Shipments

To maintain safe and damage-free delivery of our customers' shipments, Union Pacific has established restrictions on the allowable weight of rail shipments moving across our rail lines. Customers that are shipping heavy-axle cars should send a clearance request prior to shipment to determine if the rail lines involved in the route can handle the gross weight. The request must include: shipper and origin, consignee and destination, commodity and routing (including a junction point if the load is traveling off-line), phone number and fax number for a response. Local UP shipments will be cleared within two (2) business days.

See our Allowable Gross Weight page for a map and additional details.

Anti-Bribery & Anti-Corruption Policy

Union Pacific's Values Statement emphasizes high ethical standards to ensure that the Company maintains and enhances its solid reputation as one of America's leading and most recognizable companies. As part of this commitment to values, Union Pacific, its employees and its business partners are bound to comply with the federal government's Anti-Bribery & Foreign Corruption Policy.

Demurrage (Chargeable Events)

See Accessorial Tariff UP 6004 for details on extra-services charges for most shipments. These include Demurrage (General), Demurrage (Chargeable Events), overloads and diversions.

Our top priority is to provide safe, reliable transportation for our customers. Part of that commitment is to maintain a fluid and adequate supply of rail cars and to ensure that all rail car assets, both railroad- and privately-owned, are utilized as optimally as possible.

To encourage efficient use of rail cars by all parties, the transportation industry utilizes a demurrage system that charges a fee for the extended use of a freight car. These charges help offset the costs of purchasing and maintaining these assets; they also ensure that equipment utilization is prioritized and encourage equipment users to release rail cars promptly for use by other customers.

Chargeable Events System (CES) is a Web-based tool that allows you to review demurrage on a daily basis. This system also improves the approach to demurrage calculations. You'll find the following helpful to provide background and get started. CES rules information is available from Section 9 of UP6004.

See our Claims and Disputes page for information on billing problems.
