The proposed Union Pacific–Norfolk Southern rail merger is shaping up as one of the most consequential transportation deals in decades. And US agriculture is emerging as one the most worried – stakeholder groups. While the railroads pitch a coast‑to‑coast network that boosts efficiency and reliability, farm organizations warn it could tighten an already constrained rail landscape, raise shipping costs, and ultimately squeeze farm incomes and food consumers alike.
The deal, announced in July 2025, would see Union Pacific acquire Norfolk Southern in a stock‑and‑cash transaction valuing NS at about $85 billion. The merged railroad would operate under the Union Pacific name and span more than 50,000 route miles across 43 states, linking around 100 ports and forming the first coast‑to‑coast Class I network in U.S. history.
Shareholders of both companies approved the transaction in late 2025, but the merger is far from a done deal. The railroads filed their initial application with the Surface Transportation Board (STB) in December 2025, but it was rejected in January 2026 as incomplete due to documentation and impact‑analysis gaps. Union Pacific and Norfolk Southern have told regulators they intend to refile a revised, roughly 7,000‑page application by the end of April 2026, restarting what is expected to be a lengthy, high‑profile review process.
Union Pacific and Norfolk Southern frame the merger as a classic “end‑to‑end” combination that links largely complementary territories rather than overlapping mainlines. In their public messaging, the companies argue that a single integrated network will reduce handoffs between carriers, cut dwell times in interchange hubs, and make long‑haul freight more predictable for shippers. Executives emphasize that fewer interchanges should translate into fewer chances for delay, making the merged railroad a more reliable partner across the continental supply chain. The railroads also argue that a coast‑to‑coast system will enhance competition by allowing them to go head‑to‑head with other large carriers on key lanes, rather than splitting east‑west traffic through shared gateways.
US farm groups, however, seem to have a very different point of view. The American Farm Bureau Federation (AFBF) and other agricultural organizations are warning that the merger would “further exacerbate agricultural shippers’ already limited transportation options.” Rail is a critical artery for moving corn, soybeans, wheat, fertilizer, feed ingredients, and processed food products over long distances, and in many rural regions, it is the only practical option. AFBF argues that the UP–NS merger “does not create new competition for agriculture” and instead removes what little leverage shippers still have.
Several key factors heighten the ag sectors concerns about the proposed merger:
- Roughly 95% of grain elevators are already “captive” to a single railroad, with no competing carrier at the origin.
- Demand for rail service in agriculture is highly inelastic – when rates rise, farmers cannot simply stop shipping or quickly switch to trucks or barges.
- STB data show that farm‑product rail revenue above variable cost has more than doubled since 2004, suggesting agriculture is carrying a growing share of cost recovery as competitive pressures weaken.
For agricultural shippers, the most immediate fear is the loss of routing and bargaining options at key gateways such as Chicago, St. Louis, and New Orleans. Today, elevators, grain merchandisers, and processors can sometimes play Union Pacific and Norfolk Southern against each other at these interchange points, using alternate routings to negotiate better rates and service. A combined railroad would eliminate this leverage.
Analyses cited by farm groups estimate that a merged UP–NS could account for roughly 44% of total originated carloads across major commodity groups and more than one‑third of all grain rail movements nationwide. Farm Bureau warns that this concentration would make agricultural shippers more vulnerable to pricing and service decisions “they cannot control,” with cost increases rippling through the broader food supply chain. Transportation, marketing, and storage expenses for farmers are already projected to reach a record 14 billion dollars in 2026, and higher rail rates or degraded service could further tighten farm margins.
Ag stakeholders have also highlighted the risk that grain and fertilizer could be deprioritized in favor of higher‑margin or higher‑volume freight. During peak seasons, even modest delays in railcar placement or transit can translate into bottlenecks at country elevators, missed export windows, and localized basis collapses that depress prices received by farmers. As one Farm Bureau analysis puts it, when competitive pressure disappears, “farmers do not ship less – they get paid less.”
Personally, I’m rarely one to argue against free enterprise, capitalism, and mergers, but with several large farm groups making such strong arguments against this particular rail merger, it’s making me think much more deeply about the subject. It will be interesting to see how all of this plays out. (Sources: American Farm Bureau Federation, Supply Chain Dive, Southeast AgNET, Reuters)
