Union Pacific, Norfolk Southern Submit New Data to Regulators in $85 Billion Merger Bid

OMAHA, Neb. — Union Pacific and Norfolk Southern submitted the first portion of supplemental information requested by federal regulators on July 7, a key step in their pursuit of an $85 billion merger that would create the first single-line transcontinental railroad in the United States.

The filing addresses specific questions from the Surface Transportation Board (STB) regarding the railroads' influence over critical neutral rail terminals and equipment pools. This submission comes after the STB conditionally accepted the carriers' revised merger application on May 28, 2026, but put the formal review process on hold pending the receipt of this additional data.

The information provided this week focuses on the railroads' stakes in the Terminal Railroad Association of St. Louis (TRRA), the Kansas City Terminal Railway (KCT), and the freight car cooperative TTX. Both TRRA and KCT are crucial interchange points jointly owned by several major Class I carriers, facilitating the handoff of traffic between competing railroads. In their filing, Union Pacific and Norfolk Southern reiterated their position that they do not exercise control over these entities. To underscore their commitment to maintaining neutrality at these hubs, the companies offered to divest their ownership stakes if the merger is approved.

This filing is the first of two expected submissions. The STB has set a deadline of July 27, 2026, for the railroads to provide all requested supplemental information. The second filing is anticipated to address the enhanced competition aspects of the proposed combination, a central point of scrutiny for regulators.

The proposed merger, first formally submitted to the STB in December 2025, aims to connect Union Pacific’s extensive network across 23 western states with Norfolk Southern’s operations in the eastern U.S. The railroads argue that creating a seamless, end-to-end network will eliminate inefficient interchanges, which can add 24 to 48 hours to cross-country shipments. They project the merger will generate approximately $3.5 billion in annual savings for shippers by creating a more robust competitor to long-haul trucking and putting downward pressure on freight prices.

The path to regulatory approval has been methodical. After the railroads filed a notice of intent in July 2025, their initial application in December 2025 was rejected by the STB in January 2026 for being incomplete. The carriers submitted a revised and more detailed application on April 30, 2026, which the STB accepted for consideration on May 28, triggering the current request for more data before the official review clock starts.

In their amended application, the railroads stated they used comprehensive traffic data from all six North American Class I railroads—a first for a merger analysis—to identify new growth opportunities. This analysis led them to increase the number of planned premium intermodal lanes from six to seven, including a new route connecting Northern California with the Southeast. The companies assert they have sufficient equipment and infrastructure capacity to handle the projected growth without compromising service.

Union Pacific CEO Jim Vena stated in an April press release that the analysis confirms the merger “enhances competition and delivers real public benefits that make America’s supply chain stronger.” The railroads hope to secure final approval and complete the transaction by mid-2027.

In our experience, while large-scale mergers like this promise billions in shipper savings, the reality for small and mid-sized businesses can be more complex. The integration of two massive rail networks is a monumental task, and operational hiccups are almost inevitable. We've seen clients suffer from service disruptions, altered routes, and unpredictable pricing shifts during similar consolidations. Relying on a single, newly-merged carrier without a backup plan is a significant risk. Businesses should be actively modeling the potential impacts on their logistics costs and delivery times now, not after the deal closes. This is precisely the kind of strategic planning C&S Finance Group LLC assists with through our supply chain optimization services. We help companies build resilient, multi-modal logistics networks that can weather these industry shifts.

Once Union Pacific and Norfolk Southern submit their final round of information by the July 27 deadline, the next step will be for the STB to deem the application complete. This will officially commence the formal evaluation and environmental review process, setting the stage for a final decision on a deal that could fundamentally reshape North American freight transportation.
