- Union Pacific and Norfolk Southern propose an $85B merger to form the first transcontinental U.S. railroad controlling over 40% of freight volume.
- The Surface Transportation Board unanimously rejected the initial filing as incomplete under 49 CFR Part 1180, requiring a corrected refiling.
- Major rail unions oppose the deal over safety and enforceable job protections, while shippers and lawmakers warn of higher rates, weaker service, and reduced competition.
- UP/NS tout roughly $2.75B in annual efficiencies and strong shareholder support, but the transaction faces intense antitrust and public-interest scrutiny.

Regulatory Status and Hurdle
On January 16, 2026, the STB unanimously rejected the merger application filed by UP and NS on December 19, declaring it incomplete because essential information required under 49 CFR Part 1180 was missing. This rejection is without prejudice, meaning the applicants may refile a corrected application.
Stakeholder Positions
Unions: The Brotherhood of Locomotive Engineers and Trainmen (BLET) and the Brotherhood of Maintenance of Way Employes Division are strongly opposed. Their concerns include safety—including risks resurfacing in the wake of the East Palestine derailment—unclear job guarantees, and the possibility that less profitable branch lines will be offloaded to short lines, reducing service quality.
Shippers & Industry Groups: Agricultural, chemical, and fuel industry groups warn that the merger could increase freight rates, reduce service competition, and damage businesses dependent on reliable rail logistics. They demand the STB enforce rigorous safeguards.
Corporate and Supporters: UP and NS argue the merger would yield efficiencies worth about $2.75 billion annually, reduce delays by eliminating interchanges, and strengthen service for large-scale freight operations. Supporters also cite shareholder approval (99% in favor) and endorsements from certain stakeholders.
Strategic Implications
The merger would deeply reshape rail infrastructure in North America. With UP–NS controlling over 40% of freight volumes and spanning roughly 50,000 route miles across 43 states, the combined carrier would approach dominance, raising competitive concerns.
Labor relations may become strained if commitments on job security, relocation, and seniority aren’t enforceable. Job protections promised by UP are high-level; however, unions criticize them as lacking sufficient detail or enforceability.
Supply chains reliant on sensitive, time-critical goods (agricultural, fuel, chemical) face elevated risk from service disruption or rate hikes. Captive shippers (those with few alternative carriers) would be especially vulnerable under reduced competitive pressure.
Open Questions & Risks Ahead
- Refiling Timeline & STB Standards: Can UP and NS supply the missing information (system-wide impact, market share projections, effects on non-interline traffic) to satisfy STB rules? An intended refile letter was expected by February 17, 2026.
- Enforceable Labor Protections: Will UP provide detailed, binding terms for seniority, job location, relocation costs, and attrition? Without strong provisions, unions’ opposition may persist.
- Competitive Safeguards: How will STB ensure that competition among railroads and between rail and trucking remains fair? Will remedies be imposed for captive shippers?
- Operational Impact: What will changes to yards, terminals, and facility usage (including idling) look like in practice, especially in gateway cities? How much overlap exists, and how much real cost can be saved without service losses?
- Political & Antitrust Pressure: With bipartisan senators, shipper associations, and public interest coalitions pushing back, political dynamics may drive stricter conditions or even block approval despite revised filings.
Supporting Notes
- The merger would create a railroad handling over 40% of U.S. freight volumes, spanning about 50,000 route miles across 43 states.
- The STB found the UP-NS application filed on December 19, 2025 incomplete, requiring resubmission to satisfy regulatory requirements under 49 CFR part 1180.
- Unions representing more than half of UP/NS workers publicly opposed the merger citing safety risks, job losses, and higher costs.
- UP’s CEOs claim potential annual synergy savings of approximately $2.75 billion and describe the merger as improving efficiency by eliminating rail interchanges.
- Shareholder votes for both companies showed ~99% support for the deal.
- Shipper groups and industry coalitions (e.g., Agricultural Retailers Association, American Fuel & Petrochemical Manufacturers) have urged rigorous competition protections and raised concerns about service and rate increases.
