Mega Rail Acquisition Will Impact Trucking Freight Volumes

Share this Article:

The U.S. transportation industry is bracing for a transformational shift as Union Pacific (UP) moves to acquire Norfolk Southern (NS) in one of the largest rail mergers in decades. The proposed acquisition would create a coast-to-coast rail giant connecting the West Coast, Midwest, and Eastern Seaboard—effectively redrawing the competitive map of North American freight.


While the deal is still pending regulatory approval, its implications are already rippling through the logistics sector. Chief among them is the expected impact on the trucking industry, especially in areas such as:

  • Freight volumes (in trucking tons)
  • Cost per mile for freight movement
  • Trucking profit margins
  • Trucking bankruptcies
  • Consolidation and mergers across transportation sectors

This article breaks down each of these impacts in detail and explains how industry players should prepare for the coming realignment.


Rail and Trucking: Interlinked but Competitive

For decades, rail and trucking have operated in a complementary yet competitive fashion. Rail moves about 28% of U.S. freight ton-miles, while trucking dominates the short-haul and last-mile segments with about 72% of freight by tonnage. The rise of intermodal freight, where goods are shipped via multiple modes (usually rail + truck), has intensified this relationship.


The Union Pacific–Norfolk Southern merger would create a truly transcontinental rail system, enabling uninterrupted rail service from Los Angeles to Atlanta, and from Seattle to the ports of Virginia. This significantly enhances rail's competitive position over long-haul trucking, especially for shippers looking to cut costs.


How the Merger Will Impact Trucking Freight Volumes


Shift to Intermodal Rail

One of the first and most visible consequences of the acquisition will be a significant shift of freight from trucks to rail, especially intermodal shipments.


The newly combined rail network will offer:

  • More direct intermodal corridors
  • Lower transit times between major ports and inland hubs
  • Economies of scale that reduce the cost per container


Major corridors likely to see freight diversion from truck to rail include:

  • Los Angeles ↔ Atlanta
  • Dallas ↔ Charlotte
  • Chicago ↔ Norfolk
  • Kansas City ↔ Savannah


According to industry estimates, this shift could pull as much as 5–8% of truckload freight volume off the highways over the next three to five years.


Estimated Trucking Tons Lost

The American Trucking Associations (ATA) reports that the U.S. trucking industry hauls about 11.5 billion tons of freight annually. If 4–5% of that moves to rail, the trucking industry could lose over 400 million tons per year in long-haul freight—a staggering blow concentrated on large national carriers and long-haul routes.


Short-haul and regional carriers will be less affected, but OTR (over-the-road) carriers will bear the brunt.


Cost Per Mile: Downward Pressure


How Rail Lowers Freight Costs

Railroads move freight more efficiently over long distances. According to the Association of American Railroads (AAR), trains can move a ton of freight over 470 miles on a single gallon of fuel. This efficiency translates to lower rates for shippers.


Whereas long-haul trucking averages $2.05 per mile, intermodal rail can offer rates closer to $0.85–$1.15 per mile, especially on lanes over 1,000 miles.


The combined UP-NS network will allow for more direct east-west intermodal services, cutting out handoffs and inefficiencies. As a result:

  • Rail rates may drop 5–10% in targeted lanes
  • Trucking rates will feel downward pressure, especially in contract negotiations
  • Brokers and shippers will have more leverage when choosing modes


Margin Squeeze on Trucking

At the same time, trucking costs continue to rise due to:

  • Fuel price volatility
  • Equipment and insurance inflation
  • Driver shortages and wage hikes
  • Regulatory compliance costs


This divergence between rising costs and declining pricing power could compress profit margins industry-wide—especially for carriers unable to pivot into regional, niche, or intermodal-support roles.


Impact on Trucking Profits


Profitability Trends

Public carriers like Knight-Swift and J.B. Hunt have already flagged lower operating ratios in recent quarters due to soft volumes and competitive pressure. This trend will likely deepen post-merger.


Mid-size carriers operating in high-volume corridors—particularly from the Midwest to the Southeast—will face:

  • Reduced revenue per truck
  • Higher empty mile ratios
  • Tougher rate negotiations


Forecasts suggest that average net profit margins in truckload freight could fall from 6.5% in 2023 to under 4% by 2026 for those heavily exposed to long-haul lanes now being targeted by rail.


Winners and Losers


Winners:

  • Trucking companies with intermodal partnerships
  • Regional LTL carriers
  • Drayage and first-mile/last-mile operators


Losers:

  • Long-haul OTR operators
  • Non-asset 3PLs with limited modal flexibility
  • Carriers with high fixed costs and low rate flexibility


A Surge in Trucking Bankruptcies?


Current Strains

Even before this rail acquisition, trucking bankruptcies had been on the rise. According to Broughton Capital and FreightWaves, over 1,600 carriers exited the market in 2024, largely due to:

  • Spot rate softness
  • Fuel cost volatility
  • Increasing debt loads from pandemic-era fleet expansions


Merger-Related Fallout

As the merged UP-NS entity pulls freight volume and pricing power away from trucks, expect a second wave of bankruptcies—especially among:

  • Small carriers dependent on spot freight
  • Mid-size fleets locked into uncompetitive contract terms
  • Operators with high leverage or limited cash flow


Estimates suggest 2,000–2,500 additional carrier exits by 2027. The fallout will hit some regions harder than others—particularly the Southeast, Ohio Valley, and Southern California.


Transportation Mergers: Domino Effect


Trucking Consolidation Will Accelerate

To survive and compete, many trucking firms will pursue:

  • Strategic M&A to gain scale and diversify offerings
  • Tech integration for load optimization and routing
  • Modal diversification into LTL, final mile, or warehousing


Recent examples:

  • Knight-Swift acquiring U.S. Xpress
  • TFI International expanding its LTL and dedicated divisions
  • Werner and ArcBest investing heavily in 3PL technology


Expect more roll-ups of regional players and increased activity in distressed asset sales.


Rail-Broker Collaboration Will Grow

This merger may also encourage tighter integration between rail carriers and logistics providers. Look for:

  • Rail–broker joint ventures
  • Co-branded intermodal offerings
  • Tech-driven visibility platforms to support rail-truck integration


Truckers who embrace these changes and reposition as logistics partners—not just asset providers—stand to benefit.


What This Means for Shippers, Brokers, and Drivers

Shippers

Pros:

  • Lower rates on long-haul freight
  • Better intermodal coverage from coast to coast
  • More carrier options in integrated supply chains


Cons:

  • Learning curve in managing intermodal freight
  • Risk of delays during rail network integration
  • Less redundancy in modes if trucking capacity contracts


Freight Brokers

Pros:

  • Opportunity to offer modal flexibility and optimization
  • Chance to grow intermodal brokerage offerings


Cons:

  • Margin pressure on traditional TL brokerage
  • Need to invest in rail rate knowledge and capacity access


Truck Drivers

Long-haul drivers will see the biggest impact:

  • Potential for reduced miles and earnings
  • Consolidation of routes and terminals


But growth may emerge in:

  • Regional driving
  • Port and terminal drayage
  • Dedicated, private fleet operations


Retraining and geographic flexibility will be key to long-term stability.


Regulatory and Infrastructure Outlook


Surface Transportation Board Scrutiny

The STB is reviewing the UP–NS deal carefully, focusing on:

  • Market power and competition
  • Service quality during integration
  • Access for short-line railroads


Expect some conditions imposed—like terminal access provisions or service guarantees—but the merger is likely to proceed, given the precedent set by recent CP–KC Southern consolidation.


Infrastructure Investment Boom

Post-merger, expect:

  • New intermodal terminals
  • Upgraded rail yards and drayage infrastructure
  • Greater emphasis on digital platforms for shipment visibility


Trucking companies with the capital to co-invest or co-locate near these hubs will benefit the most.


Conclusion: Disruption Is Opportunity for the Prepared

The Union Pacific–Norfolk Southern acquisition represents more than a business deal—it’s a strategic inflection point for the transportation industry.


While trucking volumes, profit margins, and company count may shrink in the near term, those who adapt will find new niches, new partners, and new ways to serve a rapidly evolving freight economy.

The winners will be:

  • Intermodal-savvy
  • Tech-forward
  • Financially disciplined
  • Strategically agile


Those who cling to the status quo? They may find themselves outmaneuvered—not just by railroads, but by the freight ecosystem of tomorrow.

The transportation industry runs on thin margins, constant movement, and relentless regulatory pressure. Trucking companies focus intensely on fuel costs, driver pay, equipment expenses, insurance premiums, and freight rates. Yet one of the most overlooked forces affecting profitability often sits quietly in the background: hidden tax matters . While taxes rarely dominate daily operational conversations, they significantly influence the true cost per mile, cash flow, and long-term financial stability of transportation companies. Many carriers unknowingly overpay taxes, misapply exemptions, or overlook compliance obligations that could trigger audits and penalties. In an industry already challenged by fluctuating freight demand, rising operating costs, and tightening credit markets, hidden tax issues can quietly erode profitability. Understanding these hidden tax matters is no longer optional—it is essential. Below are several of the most common yet frequently overlooked tax issues affecting the transportation industry today. The Complexity of Fuel Tax Compliance Fuel taxes represent one of the largest tax burdens for trucking companies, yet many fleets underestimate the complexity of managing them correctly. The International Fuel Tax Agreement (IFTA) requires interstate motor carriers to track fuel purchases and miles traveled in every jurisdiction. On the surface, IFTA appears straightforward. However, the reality is far more complex. Carriers must ensure: Accurate mileage tracking by jurisdiction Proper reporting of taxable vs. non-taxable miles Correct classification of equipment Accurate fuel purchase documentation Errors in any of these areas can create major tax liabilities. Audits frequently reveal inaccurate mileage reporting or missing fuel receipts, leading to assessed taxes, penalties, and interest . Even more concerning, many companies fail to optimize fuel tax credits. When carriers purchase fuel in high-tax states but drive in lower-tax states, they may unknowingly leave money on the table by failing to properly reconcile credits. For fleets operating nationwide, these small discrepancies can add up to hundreds of thousands of dollars annually . Sales and Use Tax on Equipment Purchases Purchasing tractors, trailers, and other equipment represents one of the largest capital investments for trucking companies. Yet sales and use tax rules related to these purchases vary widely by state. Many transportation companies assume equipment purchased in one state is taxed only in that state. However, multiple jurisdictions may claim tax authority depending on: Where the equipment is titled Where it is first used Where the company has nexus Where the equipment operates For example, a tractor purchased in one state but operated in another may trigger use tax obligations in the operating state. Failure to properly address these obligations can result in significant audit exposure. Conversely, many companies miss legitimate sales tax exemptions available to motor carriers. Some states provide exemptions for rolling stock used in interstate commerce, while others offer partial exemptions or special tax treatments. Companies that fail to structure equipment purchases correctly may pay taxes that could have been legally avoided. Property Taxes on Rolling Stock Another often-overlooked tax burden involves property taxes on tractors, trailers, and other equipment . Many jurisdictions assess property tax on rolling stock based on asset value. Because equipment values can be substantial, property taxes quickly become a major operating expense. However, many transportation companies fail to properly manage this tax category. Common issues include: Incorrect asset valuations Equipment still listed after disposal Improper asset classifications Failure to claim allowable deductions Without careful review, companies may pay property taxes on equipment that has already been sold or retired. In addition, some jurisdictions allow apportionment based on miles traveled , which can significantly reduce property tax liabilities for interstate fleets. Companies that fail to take advantage of these rules often overpay. Payroll Tax and Worker Classification Risks Driver classification continues to be one of the most heavily scrutinized areas of tax compliance in transportation. Many carriers rely on independent contractors to maintain flexibility and reduce payroll costs. However, federal and state regulators increasingly challenge these classifications. If regulators determine that drivers classified as contractors should have been treated as employees, companies may face substantial liabilities, including: Payroll tax assessments Unemployment insurance contributions Workers’ compensation obligations Penalties and interest Several states have adopted stricter worker classification tests, such as the ABC test , which makes it significantly harder to classify drivers as independent contractors. Misclassification issues often emerge during audits triggered by unemployment claims or labor disputes. By the time these issues surface, liabilities may have accumulated over several years. State Income Tax and Nexus Exposure As transportation companies operate across multiple jurisdictions, determining where they owe state income tax becomes increasingly complex. Traditionally, many carriers believed they only owed income tax in the state where their headquarters was located. However, economic nexus rules and evolving tax laws have expanded state tax authority. Today, a trucking company may create tax nexus in a state simply by: Driving through the state regularly Delivering freight to customers within the state Maintaining equipment or terminals there Although Public Law 86-272 offers limited protections for certain types of interstate commerce, it does not always apply to transportation companies in the way many believe. Failure to properly address state income tax obligations can expose companies to multi-state audits and retroactive tax assessments . Tolling, Road Use Taxes, and Infrastructure Fees In addition to traditional taxes, transportation companies increasingly face non-traditional tax burdens such as tolls, highway use taxes, and infrastructure funding mechanisms. Examples include: The Heavy Vehicle Use Tax (HVUT) State highway use taxes Mileage-based road usage charges Increasing toll infrastructure Many jurisdictions view trucking companies as key contributors to infrastructure funding, and new tax structures continue to emerge. Because these taxes often operate outside traditional tax systems, they can easily escape attention during financial planning. However, when combined, they significantly impact the true cost per mile to move freight . Tax Credits and Incentives That Carriers Miss While many transportation companies worry about tax liabilities, they often overlook valuable tax credits and incentives available to the industry. Examples include: Fuel efficiency incentives Alternative fuel credits Equipment modernization credits State economic development incentives Training and workforce development credits In some cases, carriers investing in new equipment or green technologies may qualify for significant tax benefits. However, many companies never claim these credits simply because they are unaware they exist. Tax credits can directly reduce tax liability dollar-for-dollar, making them one of the most powerful financial tools available to transportation companies. Audit Exposure in the Transportation Industry The transportation industry remains a frequent audit target due to its multi-state operations and complex tax obligations. Common audit triggers include: IFTA discrepancies Sales and use tax reporting inconsistencies Payroll classification disputes Equipment purchase reporting State income tax filings Audits rarely focus on a single tax category. Instead, they often expand into multiple areas once regulators begin reviewing company records. For companies without strong tax compliance processes, audits can quickly become expensive and time-consuming. However, companies that proactively review their tax exposure often discover refund opportunities and risk reduction strategies before regulators ever arrive. The Connection Between Hidden Taxes and Cost Per Mile Every tax obligation ultimately feeds into one critical metric in the transportation industry: cost per mile . Fuel taxes, equipment taxes, payroll taxes, and infrastructure fees all contribute to the total cost required to move freight. Yet many companies underestimate the role tax strategy plays in controlling that number. When tax issues remain hidden or unmanaged, they inflate operating costs in ways that may not immediately appear on financial statements. Over time, these hidden costs can affect: Freight pricing strategies Profit margins Equipment investment decisions Cash flow management Company valuation In a competitive freight market, even small improvements in tax efficiency can significantly impact overall profitability. Why Transportation Companies Must Take a Proactive Approach The most successful transportation companies no longer treat tax compliance as a year-end accounting task. Instead, they approach it as a strategic operational function . Proactive tax management includes: Regular tax exposure reviews Multi-state tax compliance analysis Equipment purchase planning Worker classification evaluations Fuel tax optimization By identifying hidden tax issues early, companies can avoid penalties, recover overpaid taxes, and strengthen financial performance. More importantly, proactive tax planning provides leadership teams with a clearer understanding of their true operating costs . The Industry Cannot Afford to Ignore Hidden Tax Issues The transportation industry continues to face major economic pressures, including fluctuating freight demand, rising insurance costs, equipment shortages, and driver challenges. Hidden tax matters only add to that pressure. Yet these issues often remain buried within accounting systems, compliance processes, or outdated operational practices. Companies that ignore them risk: Overpaying taxes Facing unexpected audits Losing competitive advantage Reducing profitability The good news is that many of these issues are correctable once identified . Call to Action: Take Control of Your Transportation Tax Exposure Hidden tax issues rarely fix themselves. They require intentional review and proactive management. Transportation companies should regularly ask themselves: Are we overpaying fuel taxes? Are our equipment purchases structured correctly for sales tax? Are we properly managing property taxes on rolling stock? Are driver classifications defensible under current regulations? Are we exposed to multi-state tax risks? If leadership teams cannot confidently answer these questions, it may be time for a comprehensive tax review. The transportation industry already operates in a challenging economic environment. Companies cannot afford to let hidden tax matters quietly erode profitability. Now is the time to uncover those hidden tax issues, strengthen compliance, and ensure your company keeps more of the revenue it earns moving freight across America. Because in trucking, every penny per mile matters.
