A proposed $85 billion merger between two major U.S. railroads is drawing scrutiny in Montana, even though neither company dominates the state’s rail lines. The plan would combine Union Pacific and Norfolk Southern into the largest freight railroad in the country, spanning more than 50,000 miles across 43 states.
According to Daljoog News analysis, the concern in Montana is less about track ownership and more about market power. Even limited changes in rail competition can ripple across agricultural pricing, consumer goods distribution, and export access in a state heavily dependent on freight.
The merger application now sits before the Surface Transportation Board, the federal body that oversees railroad consolidation. Its decision will determine whether the first coast-to-coast single-line railroad in modern U.S. history becomes a reality.
What Happened?
On July 29, 2025, Union Pacific announced plans to acquire Norfolk Southern in an $85 billion transaction. If approved, the deal would create the largest railroad in the United States by route miles.
Union Pacific operates more than 32,000 miles of track in 23 states, primarily west of Chicago. Norfolk Southern runs roughly 19,400 miles in 22 eastern states. Together, they would form a transcontinental system linking East and West without requiring freight transfers between separate rail companies.
The six largest freight railroads in North America — known as Class I carriers — currently divide the continent into western, eastern, and Canadian spheres. Decades of consolidation reduced what was once a crowded industry to just six dominant players.
Union Pacific argues the merger would streamline operations. Company leadership says a single-line system could reduce shipping bottlenecks, cut costs for customers, and remove an estimated two million trucks from U.S. highways each year.
Federal regulators, however, rejected the railroads’ initial merger application in January, citing incomplete information. The companies have said they will resubmit with additional documentation. A full regulatory review, if accepted, could last more than a year.
Why This Matters
At first glance, Montana seems peripheral to the deal. More than 90% of the state’s rail mileage — about 3,400 miles — is controlled by BNSF Railway. Union Pacific operates only about 125 miles in Montana, mostly serving Butte. Norfolk Southern has no track in the state.
Yet Montana’s economy depends heavily on rail freight. Grain, energy products, timber, and consumer goods all rely on long-haul rail networks that extend beyond state lines.
If Union Pacific and Norfolk Southern merge, they would control more than 40% of U.S. freight rail traffic. That level of concentration could affect shipping rates nationwide, including for Montana producers sending grain to eastern export terminals.
Farmers near Great Falls, for example, might not see Norfolk Southern locomotives locally. But if their shipments move eastward over connecting rail lines, pricing structures could shift under a merged system.
Montana’s congressional delegation and Attorney General Austin Knudsen have signed letters urging federal regulators to conduct a thorough and rigorous review. Their concerns center on pricing, competition, and potential service disruptions.
History adds weight to those concerns. Rail mergers in the 1990s, including Union Pacific’s 1996 acquisition of Southern Pacific, triggered severe service breakdowns. Rail yards are clogged with stalled trains, and delays cost companies billions.
The disruption was so severe that federal regulators imposed a temporary moratorium on major mergers in 2000 and later introduced stricter review standards. No large railroad has successfully merged under those revised rules in the past quarter-century.
What Analysts or Officials Are Saying
Union Pacific leadership maintains that the merger would increase efficiency. Executives argue that a unified coast-to-coast railroad would reduce interchange delays and improve reliability, particularly in the Midwest.
BNSF Railway strongly opposes the deal. The company argues it would reduce competition and give the combined entity excessive leverage over shippers.
Montana officials appear cautious. Lawmakers emphasize the state’s dependence on agricultural exports and warn that even short-term service interruptions during harvest season could carry high economic costs.
A joint letter signed by U.S. senators from multiple states warned that disruptions on a merged network could delay shipments, spoil crops, and narrow access to global markets.
The debate has also reached Montana’s state legislature. Both Union Pacific and BNSF have engaged in direct outreach to policymakers, each presenting sharply different projections about pricing and reliability.
For Montana businesses, the concern is practical rather than ideological: Will freight costs rise, and will service remain stable?
Daljoog News Analysis
The merger debate underscores a central reality of modern railroading: geography matters less than network control.
Montana may not host Norfolk Southern track, but its producers rely on national freight corridors. When market concentration increases at the national level, peripheral states often feel the effects first.
BNSF’s dominance within Montana complicates the conversation. On one hand, a stronger Union Pacific could introduce competitive pressure in western markets. On the other hand, a transcontinental giant could negotiate from a position of unmatched scale.
Regulators will likely focus on whether the merger enhances efficiency without undermining competition. The bar for approval remains high under post-2000 rules.
Montana’s leaders appear to recognize that rail service disruptions during harvest or peak shipping seasons would strike directly at the state’s economic foundation.
The debate also reflects a broader national trend toward industrial consolidation. Railroads remain critical infrastructure. Unlike many industries, their networks cannot be easily duplicated or replaced.
What Happens Next
Union Pacific and Norfolk Southern are expected to resubmit their merger application with expanded documentation. The Surface Transportation Board must first determine whether the filing is complete before launching a formal review.
If regulators accept the revised application, the review process will likely extend well into next year. Public comment periods, economic modeling, and competitive impact studies will shape the final decision.
Montana officials are expected to continue pressing for safeguards protecting agricultural producers and rural shippers.
Even if approved, integration would pose logistical challenges. Rail industry observers will closely watch whether the companies can avoid the service disruptions that plagued past consolidations.
