US railroad Union Pacific made money by charging fuel costs for the Iran war to cover its costs.

U.S. railroad Union Pacific collected more than $91.1 million in fuel surcharges during the second quarter compared to what it paid for fuel, a filing made with the Surface Transportation Board and first reported by.

These excess surcharges increased Union Pacific's profits, highlighting criticisms from some shippers who believe that surcharges intended to recoup the rising costs of petroleum due to U.S.-Israeli war against Iran can be excessive.

The only U.S. transport companies to report fuel costs as well as fuel surcharge revenues to regulators is railroads. This rare insight provides a unique look at how fuel surcharges improve company profits.

Union Pacific says its fuel surcharge increases are in line with industry standards. STB filings revealed that only Norfolk Southern, CSX, and BNSF had excesses of $3.6 and $8.4 millions respectively during the second quarter.

Union Pacific stated that fuel surcharges were a part of the total cost they negotiate with their customers. They also take this into consideration when choosing Union Pacific.

Union Pacific reported last month that fuel surcharges increased earnings by 14 cents per share during the second quarter. Based on the number of shares outstanding, this amounts to $83.2 millions in profit.

NORFOLK NORTHWEST MERGER

Union Pacific seeks regulatory approval for the $85 billion purchase of Norfolk Southern in order to create the first railroad operator that spans?the entire continental United States.

According to the company, the merger will result in a 36% market share on carloads. This estimate does not include the double count of interline shipments.

The Stop the Merger -Coalition includes six state attorneys general as well as rival railroads, unions, and groups representing agricultural and chemical industries. They claim that creating a railroad which has a 50% share of the domestic rail freight market would decrease competition and increase shipping costs, ultimately affecting consumers.

The coalition didn't immediately respond to an inquiry about the surcharges.

In a STB filing made this month, BNSF-owned by Berkshire Hathaway said that only Union Pacific would benefit from the proposed merger. The company noted that the resulting firm "will have all the incentives and opportunities to apply UP’s long-standing high-price strategy on a nationwide scale." BNSF declined comment.

U.S. transportation industry charges fuel surcharges based on benchmarks like the Department of Energy On-Highway Diesel Fuel Price and a proprietary formula known as a “trade factor.” Surcharges are a long-standing practice that has survived legal challenges and regulatory scrutiny for decades.

"Rail fuel charges have increased 43 cents per?mile overall since March, and are now above the previous record set in September 2008. This is not a mistake," said Kyle Henzel. He's the president and chief operating officer of shipping platform Ship.com.

There's usually a delay of up to 2 months between changes in fuel prices and surcharges on railroads. The March fuel surcharge for this year, for instance, was based off the January diesel prices, before the Iran War began.

Union Pacific's STB filing revealed that in the first quarter it collected fuel surcharges of $607.6 millions, which was $34.8 million more than what it had paid for fuel.

Union Pacific's fuel costs were $56.4 million higher than the surcharge revenue in both the first and second quarters.

Union Pacific is the only major railroad that reported fuel surcharges exceeding?fuel prices for the first half 2026.

Union Pacific and BNSF competed for dominance in the west of the United States. STB filings show that BNSF surcharges for the first half of this year were $658.1 million less than fuel costs.

The company's STB documents showed that Union Pacific generated $2.3 billion in fuel surcharges last year. This was $48 million more than it spent on fuel. (Reporting and editing by Timothy Gardner and Rod Nickel; Additional reporting and editing by Sabrina Valle and Lisa Baertlein)
