ATLANTA, GEORGIA (By Chad Archey, Energy Analytics Institute, 6.May.2026, Words: 192) — Canadian Pacific Kansas City and CSX Corporation revealed upgrades to the Southeast Mexico Express premium service. These will feature faster transit times with more origin and destination options for customers looking to reach new markets.
The new SMX premium service schedule and routing options launched 4 May 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, Mexico.

The service improvements have reduced transit times for every previously available SMX option, CPKC said on 6 May 2026 in an official statement.
These reductions range from approximately one-day-faster service between Atlanta and Dallas, and approximately 2.5 days faster between Atlanta and central Mexico.
