Emergency Fuel Purchases
While Union Pacific would prefer electronic invoices for Emergency Fuel Purchases, due to the unique nature of these POs an exception to the policy allows the invoices to be mailed.
Invoices for these purchases (indicated by the purchase order number) can be routed to the Supply Department's Fuel Group, as follows:
Union Pacific Railroad
Supply Department, Fuel Group
1400 Douglas Street, Stop 0780
Omaha, NE 68179-0780
Invoices to Union Pacific Affiliates
Invoices payable by Union Pacific affiliated companies, including Houston Belt & Terminal (HBT), Union Pacific Motor Freight (UPMF), UP de Mexico (UPDM), and Port Terminal Railroad Company (PTRR) should not be forwarded to UPRR for payment. When such invoices are received, they are returned to the supplier with a letter requesting a purchase order copy.
When the invoice and purchase order copy are re-submitted by the supplier, the original invoice is pulled and forwarded to the appropriate affiliate for payment. During this process, invoices are handled by multiple departments, resulting in delayed payment.
