Union Pacific CEO Jim Vena and Norfolk Southern CEO Mark George made their first public remarks following Monday's supplemental merger filing with the Surface Transportation Board, telling the Trains Magazine Future of Rail Symposium that their proposals are shipper-friendly and that the combined railroad will deliver broad cost savings. The filing represents a pivotal moment in one of the most closely watched rail consolidation proceedings in years, with opponents including BNSF and CPKC arguing the deal would concentrate too much market power. The STB tightened its merger review standards in 2001 after a wave of 1990s consolidations reduced the Class I railroad count to its current seven, requiring applicants to demonstrate that a transaction enhances competition and serves the public interest — a bar that UP and NS must clear in the first major merger proceeding since Canadian Pacific acquired Kansas City Southern in 2023.

At the core of the UP-NS argument is single-line service. Bill Steeves, editor of Trains Magazine, who moderated discussions with both CEOs, noted that shippers are two to three times more likely to complete a rail move when it involves a single railroad versus an interchange. Single-line service also runs 25 to 35% less expensive than a joint-railroad move, according to figures cited in the merger application. The applicants project $3.5 billion in annual savings for shippers and the removal of 2 to 2.2 million truckloads from U.S. highways — a meaningful figure for an industry that moves roughly 28% of the nation's freight ton-miles and competes directly with trucking for long-haul cargo.

The supplemental filing proposes expanding committed gateway pricing to cover double the number of shipments currently eligible, opening unit train moves — typically bulk commodities like grain — to more shippers, and creating a mechanism for shippers to access a competing railroad if service deteriorates during merger implementation. Vena expressed confidence the deal will be approved, calling it better for consumers through improved service that would lower costs relative to trucking.

"Single-line service is 25 to 35% less expensive than a joint railroad move because those costs come out — and so that is their argument, that that will save shippers $3.5 billion a year in terms of bringing trucks off the highway to this new transcontinental railroad," Steeves said, summarizing the UP-NS case.

BNSF CEO Katie Farmer pushed back sharply, saying in a statement that the new filing "does nothing to change the impact of a railroad that would have 50% market share of US rail traffic," and that the interchange protections on offer are difficult to understand, come with caveats, and apply to very few customers for only a limited time. BNSF has argued that commercial alliances — such as its partnership with CSX — can be equally effective at pulling freight off trucks without the competitive harm of a full merger.

The applicants emphasized that market share gains would come from increased competition and customer choice for single-line service, not from diminished competition. Steeves noted that the central argument is straightforward: shippers prefer dealing with one railroad, one invoice, and a single point of contact for service issues.

As the merger review unfolds, the debate between these differing views is expected to feature prominently. Steeves pointed to the merger agreement UP reached with Canadian National last week as a meaningful development that addresses Midwest overlap concerns and expands CN's reach into Kansas City and Mexico — potentially strengthening the pro-competition argument before the STB.

Week 29 AAR Traffic Data

North American rail carloads rose 3.8% in week 29, ahead of the prior four-week pace of 2.7%. Intermodal decelerated to 2.6% from 6.5% over the same comparison period. Overall North American volume was up 3.1%, down from 4.7% over the prior four weeks.

In the U.S., carloads rose 1.2% for the week, matching the prior four-week pace. Intermodal grew 3.5% year over year but slowed sharply from the 9% pace of the prior four weeks. Overall U.S. volume was up 2.5% for the week, down from 5% over the prior four weeks — a decline entirely attributable to the intermodal slowdown.

Grain has been a standout commodity all year, up approximately 13% year to date, partly due to comparisons with last year's tariff impacts. Coal remained the only category down year to date.

Among individual commodities, petroleum and petroleum products rose 11.8% for the week. Lumber and wood posted a 16.8% gain, even as the broader forest products category declined 0.7%. Metallic ores and metals increased 6.8%, driven by coke used in steelmaking, finished metal shipments, and scrap for mini mills. Autos showed strength at 2.9% for the week, rebounding from a 2.2% decline over the prior four weeks.

Mexican rails, while small in overall shipment volume compared to North America as a whole, posted the most significant gains: 18% in total intermodal units and 11% in total traffic, led by auto parts. However, year-over-year comparisons remain complicated by the tariff disruptions of the prior year.

Union Pacific Outperforms

Union Pacific stood out, posting an 8.2% volume gain for the week — more than double any other Class 1 railroad — and an 8.3% gain over the prior four weeks. The performance was driven by record domestic intermodal results for a fourth consecutive quarter, with private-asset moves, rail-owned container moves, and parcel moves all increasing. UP also gained international business that had previously been moving on BNSF, adding a competitive dynamic to the volume picture.

Canadian Railroads and Trade Tensions

CPKC was set to report earnings later in the day. CN has already signaled on its earnings call that it believes U.S.-Canada-Mexico trade tensions will resolve rationally, though Steeves acknowledged both Canadian carriers have a strong incentive to project optimism given their dependence on cross-border traffic.

CPKC CEO Keith Creel has argued that North American supply chains across the three countries are so intertwined that unwinding them would be impractical, and that the economic logic of integrated trade benefits all parties. Creel leads the only railroad linking Canada, the U.S., and Mexico.

CN and CPKC are working to diversify trade flows by routing more cargo through West Coast ports and developing Canada-Mexico land-bridge corridors. The goal is to increase direct trade between Canada and Mexico, reducing reliance on the U.S. market. Aluminum serves as a notable example: despite high tariffs, traffic continues to cross the Canadian border into the U.S. because domestic production cannot meet demand.

The broader trade landscape remains complex, with the administration imposing new tariffs on Canada and signaling reluctance to renew the USMCA, which is subject to a joint review in July 2026. How railroads navigate these tensions while maintaining cross-border freight flows remains an open question.

Symposium Highlights

The Trains Magazine Future of Rail Symposium featured additional discussions beyond the merger debate. Patrick Fuchs, chairman of the Surface Transportation Board, participated in a conversation about the regulatory outlook.

Leaders of Intramotive and Parallel Systems discussed the development of autonomous railcars and the potential trajectory of that technology over the next five years. Tom Tisa, chief commercial officer of Patriot Rail, explored how short-line and regional railroads can grow by expanding beyond traditional freight movement into transloading, warehousing, and distribution services.

Analyst Rick Patterson addressed Wall Street's focus on operating ratios and how that emphasis can negatively affect service quality and volume growth. CanDo, a Canadian company represented by Chief Commercial Officer Mike Miller, presented its approach to helping Class 1 railroads improve first- and last-mile service through more frequent, reliable, and dependable car supply.

Officials from the Federal Railroad Administration and the Association of American Railroads discussed regulatory priorities for facilitating the adoption of new technologies, including automated track inspection, automated equipment inspection, and autonomous vehicles.
