CNI Q2 2025: 8% Labor Productivity Gain Offsets Tariff-Driven Volume Drag
Canadian National Railway (CNI) delivered margin expansion and operational efficiency gains despite a macro and tariff-driven volume headwind. The quarter demonstrated the network’s resilience, with proactive cost management and strong bulk franchise performance counterbalancing merchandise and intermodal softness. Management’s reset to low single-digit RTM growth reflects a pragmatic stance amid persistent trade uncertainty, with a disciplined focus on cost control and targeted capital allocation for the balance of 2025.
Summary
- Tariff and Trade Uncertainty Shifts Volume Mix: Merchandise and intermodal softness offset bulk strength, driving a more cautious outlook.
- Operational Discipline Drives Margin Gains: Labor productivity and asset optimization protected profitability despite flat carloads.
- Strategic Cost Control Remains Central: CapEx and headcount flexibility position CNI for both near-term uncertainty and future rebound.
Performance Analysis
CNI’s Q2 performance was defined by resilience in the face of external headwinds. Revenues declined slightly on flat carloads and a modest reduction in revenue ton-miles (RTMs), as strong bulk volumes—notably grain and fertilizers—were offset by weakness in merchandise and intermodal segments. The quarter was further pressured by a repealed Canadian carbon tax surcharge, which reduced revenues but was a complete pass-through to customers, and by lower fuel prices, which provided a cost tailwind.
Operationally, the company executed decisive cost actions: mainline manifest train starts were reduced in line with a 7% merchandise workload drop, while bulk workloads rose and were handled with minimal incremental resources. Labor productivity improved 8% year-over-year, primarily through targeted furloughs and tight hiring controls. The network maintained high fluidity, with car velocity above 200 miles per day and improved dwell, supporting a 50 basis point year-over-year improvement in operating ratio. Free cash flow grew as capital expenditures were trimmed and resource deployment was tightly managed.
- Bulk Franchise Outperformance: Grain and fertilizer revenues rose 12%, with record shipments in Western Canada and strong U.S. corn exports.
- Merchandise and Intermodal Drag: Tariff impacts and a weaker industrial economy drove mix headwinds, especially in forest products, metals, and refined petroleum.
- Asset and Cost Efficiency: Locomotive availability reached 92.5%, with an 8% reduction in unit costs; 8,000 system cars and 200 locomotives were placed in storage to match demand.
Despite these pressures, proactive cost management and a nimble operating model allowed CNI to defend margins and protect cash conversion, even as the macro environment turned more volatile.
Executive Commentary
"We delivered a solid Q2 in this environment, but there is ongoing uncertainty as we look forward. As a result, we believe it is appropriate to soften our expectations for the remainder of the year, and we're adjusting to low single-digit RTM growth. Now, make no mistake about it. This is a great network. It has tri-coastal access. It serves the resource and energy-rich regions of northern Canada. It uniquely bypasses Chicago congestion and has a well-diversified book of business."
Tracey Robinson, President and CEO
"Volumes were lower due to macro and tariff overhang. We also had unfavorable mixed shift and a fuel price headwind of 4 cents. On the plus side, we're very pleased with our solid cost takeout, and same store pricing above rail inflation... We are revising our guidance to mid to high single-digit EPS growth in 2025. We're also looking at reducing our CapEx envelope for the year by about $50 million."

Strategic Positioning
1. Network Advantage and Bulk Strength
CNI’s tri-coastal network—with direct access to the Atlantic, Pacific, and Gulf—remains a core differentiator. The bulk franchise, particularly grain and fertilizers, continues to outperform, benefiting from record Canadian grain shipments and new ethanol and potash export projects. This segment anchors CNI’s resilience against cyclical softness elsewhere.
2. Proactive Cost and Resource Management
Asset-light adjustments—including furloughing over 500 train and engine employees, storing 8,000 cars, and optimizing locomotive deployment—enabled rapid cost realignment. Labor productivity gains and a focus on in-house engineering work drove efficiency, while the company maintained readiness to scale up if volumes rebound.
3. Navigating Tariff and Trade Volatility
Tariff escalation—notably U.S. duties on Canadian steel, aluminum, and softwood—has forced CNI and its customers to adapt supply chains, shifting flows intra-Canada and intra-U.S. and exploring alternative export markets. Leadership is working closely with customers and government stakeholders to mitigate impacts and capture new opportunities as trade patterns evolve.
4. Capital Allocation Discipline
With muted volume growth and ongoing macro uncertainty, CNI is tightening its capital envelope, pulling $50 million from this year’s budget and focusing growth CapEx on western corridor energy and bulk opportunities. Maintenance CapEx is being executed with higher productivity, and all growth projects are tied to contractual volume visibility and targeted returns.
5. Commercial Agility and Customer Focus
With a new interim Chief Commercial Officer, the focus is on increasing agility to capture spot market opportunities and adapt to shifting customer needs. This includes leveraging superior service to gain domestic intermodal share and intensifying execution on CN-specific growth initiatives.
Key Considerations
This quarter highlighted how CNI’s business model and operational discipline buffer against external shocks, but also revealed limits to growth under persistent macro and policy volatility.
Key Considerations:
- Tariff-Driven Mix Headwinds: Ongoing U.S. tariffs on Canadian metals, lumber, and industrial goods are reshaping volume flows and pressuring merchandise revenues.
- Bulk Segment Insulation: Grain, fertilizer, and potash strength provide a counterbalance to cyclical and trade-exposed segments, anchoring the network’s stability.
- Operational Flexibility as a Margin Lever: Proactive labor and asset management enable swift cost takeout and preserve margin in a volatile demand environment.
- CapEx Rationalization: Capital deployment is increasingly tied to visible, contracted growth, with an emphasis on capital efficiency and ROI discipline.
- Leadership Transition and Execution Focus: The interim CCO is prioritizing commercial agility and spot market responsiveness to offset structural headwinds.
Risks
CNI faces material risk from continued tariff escalation and unresolved trade negotiations, which could further dampen merchandise and intermodal volumes. Macro softness in the industrial economy, volatile currency and fuel prices, and the potential for regulatory or competitive disruption (including rail industry M&A) add to uncertainty. While operational agility mitigates some risk, persistent volume pressure could challenge margin gains if bulk outperformance fades.
Forward Outlook
For Q3 2025, CNI guided to:
- Low single-digit RTM growth versus 2024
- Margin improvement supported by continued cost discipline and mix management
For full-year 2025, management revised guidance:
- Mid to high single-digit EPS growth (down from prior outlook)
- Reduced CapEx envelope by $50 million, with further tightening possible
Management highlighted several factors that will shape results:
- Tariff and trade policy volatility could further impact volumes and mix, especially in merchandise and intermodal
- Bulk segment strength and operational flexibility are expected to support margins, but volume recovery timing remains uncertain
Takeaways
CNI’s quarter underscores the value of operational discipline and a diversified network in a volatile macro and policy environment.
- Margin Protection Through Flexibility: Proactive labor and asset management offset volume and mix headwinds, supporting profitability even as top-line growth stalls.
- Bulk Franchise as Strategic Anchor: Record grain and fertilizer shipments demonstrate the defensive value of CNI’s bulk book amid cyclical and policy-driven weakness elsewhere.
- Watch for Trade Policy Resolution: Sustained EPS and margin gains will depend on stabilization in tariff and trade dynamics, as well as continued execution on cost and capital discipline.
Conclusion
CNI delivered a disciplined quarter, with operational and financial levers cushioning tariff and macro headwinds. The reset to more modest growth expectations and CapEx discipline signals a pragmatic response to persistent uncertainty, while the network’s bulk strength and operational flexibility position the company to capitalize when trade flows normalize.
Industry Read-Through
CNI’s results offer a clear signal for North American railroads: operational flexibility and a diversified commodity mix are essential for navigating trade policy volatility and macro softness. Tariff-driven supply chain shifts are forcing both rails and shippers to adapt, with intra-national flows and alternative export routes gaining prominence. For peers, the focus on cost control, capital discipline, and commercial agility will be critical as trade and industrial headwinds persist. The quarter also highlights the growing importance of bulk franchises as defensive anchors in an uncertain environment, a dynamic likely to shape capital allocation and strategy across the sector in the coming quarters.
