Why Trains Can’t Replace Trucks in the U.S. Supply Chain

ATA warned that rail cannot replace road transport and that favoring one mode over another is unrealistic for the needs of the U.S. economy.

The American Trucking Associations (ATA) explained why proposals to shift most of the country’s freight to rail are neither viable nor practical for the U.S. economy. According to the organization, “calls to shift freight transportation from trucks to trains are nothing new, but the idea that rail can replace road transport—or that policymakers should favor one mode over another—simply does not align with reality.”

Trucks and Trains: Distinct Roles in the Supply Chain

The ATA emphasized that rail directly competes with trucks in less than 10% of the nation’s freight volume. While trains have advantages in moving bulk commodities such as coal, gravel, or grain, their role is limited when the logistics chain demands precision, speed, and reliability.
“Trains don’t deliver to hospitals, supermarkets, schools, or homes. Trucks do,” the association stressed. In the context of booming e-commerce and growing demand for same-day delivery, trucking becomes indispensable.

Infrastructure and Costs: The Major Obstacle

The ATA noted that expanding the rail network to the point of significantly replacing road transport would require thousands of miles of new tracks, additional terminals, more labor, and connections to communities that currently lack rail access.
“The cost would be exorbitant, the disruption enormous, and the benefit minimal, because trucks would still be needed to finish the job,” the association warned. In this regard, the more realistic alternative is to invest in existing highways and bridges, where nearly 75% of the nation’s freight moves today.

Sustainability: Concrete Advances in Road Transport

The ATA also highlighted the trucking industry’s progress on environmental issues. Modern trucks produce 99% fewer nitrogen oxide and particulate emissions than those from decades ago. In addition, new vehicles emit over 40% less carbon than those manufactured in 2010.
Thanks to innovation in clean technologies, alternative fuels, and more efficient engines, it now takes 60 modern trucks to generate what a single vehicle emitted in 1988.

Complementarity, Not Replacement

The ATA underscored that the debate should not focus on choosing between trains and trucks, but on recognizing that both modes complement each other. However, it firmly argued that without road transport, “every link in the supply chain would break.”
“Rail will always have its place, but when it comes to keeping America moving, trucking is not optional—it is indispensable,” the statement concluded.
