CSX Corporation (CSX) and Canadian Pacific Kansas City (CPKC) have created a new rail transportation routing option for customers across the southern U.S. with the Southeast Mexico Express (SMX), the new east-west Class 1 corridor that connects shippers in Mexico, Texas and U.S. southeast.

Officially launched on Dec. 1, 2024, the SMX is already providing automotive, intermodal and carload customers with faster transit times, greater capacity, and environmentally sustainable rail 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 & 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.”

“The launch of the SMX is a testament to our dedication to enhancing connectivity and efficiency while deepening our reach into cross-border markets,” said Joe Hinrichs, President and CEO of CSX. “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.”

This innovative service expands capacity while creating seamless, highly-reliable shipping options across three key markets. The SMX collaboration between CPKC and CSX is addressing evolving customer demands.

Schneider National, Inc., a premier multimodal provider of transportation, intermodal and logistic services, has been providing its customers with this service where they are enjoying unparalleled efficiency and reliability in their supply chains.
