-- Canadian Pacific Kansas City (CP.TO and NYSE: CP) and Nasdaq's CSX Corporation have upgraded the Southeast Mexico Express (SMX) premium service, "featuring faster transit times with more origin and destination options for customers looking to reach new markets", CP said Wednesday.
The new SMX premium service schedule and routing options launched May 4, 2026, offer "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 CP statement said.
The service improvements have reduced transit times for every previously available SMX option, while these reductions range from approximately one-day-faster service between Atlanta and Dallas, and approximately 2.5 days faster between Atlanta and central Mexico, it added.
SMX improvements are the result of capital investments in track, bridges and signal infrastructure on the former Meridian & Bigbee Railroad (MNBR) and continued investments across the corridor in Georgia, Alabama, Mississippi, Louisiana, and Texas offering greater speeds and more efficiency, according to the statement.
Shares in CP were last seen up $1.98 or 1.7% at $115.75.
