A new coalition launched in the United States is seeking to block the merger between Union Pacific and Norfolk Southern, one of the largest railroad deals in the country’s recent history. The group, called the Stop the Rail Merger Coalition, brings together rival rail companies, customer organizations, and unions, and argues that the mega-merger would reduce competition, increase costs for the industry and consumers, and add new risks to supply chains.
The coalition includes, among others, BNSF Railway, CPKC Railway, American Chemistry Council, American Farm Bureau Federation, and Teamsters Rail Conference. The opposition comes at a sensitive time, just before Union Pacific and Norfolk Southern submit a revised version of their merger filing to the federal regulatory authority.
What the merger’s opponents are challenging
The new coalition argues that the merger would create the first major U.S. rail operator with full coverage from west to east and would concentrate a massive portion of U.S. freight traffic within a single company.
Critics say such a move would directly undermine competition among operators, put pressure on rates, and affect the reliability of the network.
Opposition comes from a wide range of stakeholders, from industry groups and agricultural organizations to labor unions and direct rivals, and the dispute is being played out not only on economic grounds but also on political and regulatory ones.
How this opposition arose
The merger was announced by Union Pacific and Norfolk Southern in July 2025, in a deal valued at USD 85 billion, which would create the first major coast-to-coast U.S. rail operator.
The companies presented the project at the time as a historic step toward streamlining freight transport, reducing interchange delays, and increasing network efficiency.
In the meantime, the deal has received approval from the shareholders of both companies, but still needs the green light from the Surface Transportation Board, and the review is being conducted under stricter rules than in the past, precisely because the authority must be convinced that the merger brings clear public benefits and does not weaken competition.
BNSF was already making moves on another front
Interestingly, BNSF, now part of the anti-merger coalition, had already strengthened its own commercial ties in the eastern U.S. In August 2025, BNSF and CSX announced new coast-to-coast intermodal services, presented at the time as fast and seamless solutions between markets in the West and East.
In the same context, speculation had also emerged regarding a potential BNSF–CSX strategic move, although this was publicly denied. This shows that the major U.S. rail companies were already trying to strengthen their commercial positions even before the battle over the UP–NS merger entered its current phase.
What’s Next
Union Pacific continues to argue that the merger will improve services, reduce costs, and strengthen rail’s competitiveness against road transport.
But as opposition mounts, it is becoming increasingly clear that this is no longer just a corporate transaction, but a battle over the future shape of the U.S. rail freight market. The stakes are high, in part because the regulatory decision will reshape the industry for decades to come.
