Rail Market Update Podcast
Here’s a breakdown of the key topics and why they matter.
Section 232 Tariffs: A Major Shift for Tank Cars
One of the most impactful updates discussed in this episode is the Trump administration’s recent changes to Section 232 tariffs on metal products — specifically as they relate to rail equipment.
For the first time, tank cars imported into the U.S. from Canada and Mexico are now subject to a 25% tariff based on the finished value of the car. Previously, most freight cars were considered USMCA-compliant and entered tariff-free.
This change is significant for several reasons:
- It directly affects railcar pricing and leasing economics
- It may increase the value of the existing North American tank car fleet
- It alters how railcar components are evaluated, shifting from steel-content tariffs to finished-goods tariffs
More detailed analysis will be available in FTR’s upcoming subscription Q2 Rail Equipment Outlook.
Rail Traffic Trends: Growth Continues, with Some Divergence
Turning to recent rail traffic data, North American carload volumes have shown continued strength over the past four weeks, up 2.8% year over year, despite a slight pullback in the most recent week.

Key highlights include:
- Agriculture leading growth, up 8.9%, driven by gains across all major commodities
- Strong performance in automotive, chemicals, and petroleum products
- Improvement in previously weak areas such as forest products, including lumber and paper
On the downside, coal and the “all other” category remain the only major commodity groups posting year-over-year declines.
Intermodal Performance: Mixed Results by Geography
Intermodal traffic has also posted year-over-year gains, averaging 1.4% growth over the past four weeks, though performance varies by region:
- U.S. carriers remain relatively stable overall
- Canadian volumes have declined year over year for seven consecutive weeks
- Mexico continues to report strong growth, though initial weekly reports have been revised lower in several instances
Despite revisions, Mexico remains a clear bright spot in intermodal activity so far this year.

UPNS Merger: Revised Application Under Review
The episode concludes with an early, high-level look at the resubmitted UPNS merger application, which was filed just hours before recording.
One notable change from the original December submission is an increase in projected truck-to-rail diversions, now estimated at 2.136 million truckloads, up roughly 100,000 from the prior estimate. This adjustment stems from changes in data sources and methodology.
The revised filing also includes additional market share projections, as requested by the Surface Transportation Board (STB). While those projections are not yet clearly visible in publicly available materials, further insight is expected as supporting workpapers become available.
The STB has 30 days to accept or reject the application as complete, with industry comments on completeness due by May 8.
Final Thoughts
This episode underscores how quickly policy changes, market data, and regulatory decisions can reshape the rail landscape. From tariffs influencing equipment economics to evolving traffic trends and merger scrutiny, the implications for shippers and rail stakeholders are substantial.
