CSX Corporation and Canadian Pacific Kansas City announced upgrades to the Southeast Mexico Express premium service featuring faster transit times with more origin and destination options for customers looking to reach new markets. The new Southeast Mexico Express premium service schedule and routing options launched May 4, 2026, offer industry-best, truck-competitive transit times between southeastern markets such as Atlanta, Charlotte or central Florida, and markets in Texas and Mexico, including Dallas and Monterrey. The service improvements have reduced transit times for every previously available Southeast Mexico Express option.
These reductions range from approximately one-day-faster service between Atlanta and Dallas, and approximately 2.5 days faster between Atlanta and central Mexico. Southeast Mexico Express improvements are the result of capital investments in track, bridges and signal infrastructure on the former Meridian & Bigbee Railroad and continued investments across the corridor in Georgia, Alabama, Mississippi, Louisiana, and Texas offering greater speeds and more efficiency. The new Southeast Mexico Express dedicated train service provides two-day service between Atlanta and Dallas, with three-day service from Monterrey and four-day service from central Mexico to Atlanta.
Customers can extend their reach with new Southeast Mexico Express origins and destinations in Charlotte, Jacksonville and Central Florida. Southeast Mexico Express gives intermodal, automotive and carload customers truck-competitive transit times, greater capacity, and environmentally sustainable rail solutions. Advantages of Southeast Mexico Express include: Direct connectivity: Links to Mexico, Texas and U.S. Southeast.
Market access: Expanded connectivity to diverse origin points across North America. Faster transit times: Improved time and cost efficiency 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. The combined strength of CSX Corporation and Canadian Pacific Kansas City through Southeast Mexico Express continues to meet evolving customer demands and set new standards in North American freight.
