Enhancements to Southeast Mexico Express

On May 6, 2026, Canadian Pacific Kansas City (CPKC) and CSX Corporation announced notable upgrades for the Southeast Mexico Express (SMX), a premium rail service designed to link southeastern U.S. markets with Texas and Mexico. This joint venture promises significantly faster transit times, improved origin and destination options, and increased efficiency for freight shippers seeking to enter new markets.

The SMX service improvements, which launched on May 4, showcase reduced transit durations for a range of journeys. For instance, shipments from Atlanta to Dallas will now be completed about a day sooner than before, and transit times from Atlanta to central Mexico have been cut down by approximately 2.5 days. These enhancements are made possible through substantial investments into the underlying infrastructure of the Meridan Bigbee Railroad and ongoing upgrades across the corridor, spanning areas such as Georgia, Alabama, Mississippi, Louisiana, and Texas.

“By implementing these improvements, we aim to deliver a 20 to 45 percent acceleration in SMX transit times,” said Keith Creel, CPKC’s President and CEO, illustrating the commitment to providing tailored transportation solutions. The intent behind the SMX is to offer an unmatched rail option for shippers looking to connect with a growing number of markets within the U.S. Southeast, Texas, and Mexico.

Key Benefits of the Upgraded SMX

Among the most significant attributes of the upgraded service are:

• - Direct Connectivity: Establishing straightforward links between Mexico and the U.S. Southeast, enabling seamless freight movement.
• - Market Accessibility: Enhancing connectivity with diverse origins throughout North America, making the service appealing for a wider customer base.
• - Faster Transit Times: Boosting time and cost efficiency due to infrastructure advancements, which allow for rapid shipments.
• - Secure Transportation: Employing advanced technologies to speed up border crossings while also ensuring high levels of shipment security.
• - Environmental Sustainability: The service promotes sustainability by replacing up to 300 semi-trucks per train, contributing to a decrease in emissions.

Furthermore, the SMX offers more than just rapid transport; it provides versatile shipping options for intermodal, automotive, and bulk freight, helping industries shift goods with the speed that rivals trucking services.

CSX’s President and CEO Steve Angel echoed support for the partnership, clarifying that these upgrades exemplify CSX’s long-term commitment to bolstering the corridor's service reliability and consistency. The new dedicated train service will enable favorable shipping timelines, including two-day transit from Atlanta to Dallas, three-day services from Monterrey, and four-day services from central Mexico to Atlanta.

One of the notable early adopters of this enhanced service, Schneider National, Inc., acknowledged the benefits of this partnership. Schneider’s President and CEO Mark Rourke commented on the value of collaborative ventures in delivering innovative intermodal solutions that align with the demands of today’s logistics environment.

As CPKC and CSX integrate their resources further, they continue to reshape the North American freight landscape by meeting the evolving needs of shippers while maintaining their focus on sustainability, reliability, and market growth.

This upgraded service is expected to set new standards in freight transportation connecting customers from Texas to southeastern U.S. markets, showcasing the continued advancements in rail logistics that can fulfill modern demands for speed and efficiency.
