CPKC and CSX launch Southeast Mexico Express rail corridor

Canadian Pacific Kansas City (CPKC) and CSX Corporation have launched the Southeast Mexico Express (SMX), a new east-west Class 1 rail corridor connecting shippers in Mexico, Texas and the U.S. Southeast.

Officially operational since December, the SMX offers automotive, intermodal and carload customers faster transit times, increased capacity and more sustainable freight solutions.

“The Southeast Mexico Express has created new opportunities for our customers across all of our lines of business, including intermodal, carload and bulk, through a unique collaboration that is already proving itself in the market,” said Keith Creel, CPKC president and CEO. “With this corridor, we are leveraging the strengths of both CPKC and CSX, delivering faster transit times, greater efficiency and enhanced reliability. Together, we are providing shippers with a competitive, sustainable alternative for freight transportation.”

Joe Hinrichs, president and CEO of CSX, said, “The launch of the SMX is a testament to our dedication to enhancing connectivity and efficiency while deepening our reach into cross-border markets. This new corridor highlights how we are taking concrete, measurable actions to expand our network, enhance service, and unlock long-term growth for our customers.”

The service enables direct connectivity between the three regions, allowing for secure, efficient transportation and reducing environmental impacts by replacing up to 300 semi-trucks per train.

Schneider National, Inc., one of the early adopters of the SMX, said it is already seeing results.

“Our collaboration with CPKC and CSX on the Southeast Mexico Express represents a meaningful improvement in cross-border logistics for our customers,” said Schneider president and CEO Mark Rourke. “This new service delivers greater efficiency and reliability across the supply chain, reinforcing our commitment to seamless, flexible transportation solutions that meet the evolving needs of shippers throughout North America.”
