Canadian Pacific Kansas City (CPKC) and CSX Corporation 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.
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, 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.
Key advantages of SMX include:
- Direct connectivity: Links Mexico, Texas and U.S. Southeast.
- Market access: CPKC’s single-line network connects shippers to diverse origin points across North America.
- Faster transit times: Time and cost efficiencies supported by infrastructure upgrades.
- Secure transportation: Advanced technology expedites border crossings while enhancing shipment security.
- Environmental sustainability: Replaces up to 300 semi-trucks per train, reducing emissions.
