U.S. rules require rail mergers to show that a deal would serve the public interest and enhance competition, a step beyond merger requirements applied to other industries.

Last year, Prime Minister Donald Tusk’s cabinet amended the $36 billion airport project, which was drawn up by his nationalist predecessors, scaling down rail investments.

On March 31, 2025, Mexico’s president, Claudia Sheinbaum gave the project a shout-out at a news conference. However, official information about the project has been scant. 

The deal announced on July 29 would put roughly 40% of the nation's rail freight in the hands of a single company.

BNSF says that the service will be 24 hours faster than its standard product, and 48 hours faster than its previous service offering for the route. 

The company will work with customers in sectors affected by tariffs to help them get access to other markets, the CEO said.

Real-time insights from border crossings allow companies to re-route shipments, renegotiate supplier terms, or rebalance inventory before the ripple effects settle in.

To keep operations and supply chains stable, companies today need a freight strategy that can flex under pressure. That means going multimodal.

Speculation has been growing about a large merger in the North American rail industry under the assumption that the government will be more amenable to consolidation under President Donald Trump.

The announcement comes after months of scrutiny, including a comprehensive compliance review, along with the failure of the California High-Speed Rail Authority to address serious project deficiencies.
