04:36 PM EDT, 07/21/2025 (MT Newswires) -- Canadian Pacific Kansas City ( CP ) (CP.TO, CP) and CSX Corp. ( CSX ) said at the close of trade Monday they created a new rail-transportation routing option for customers across the southern United States, with the Southeast Mexico Express (SMX), the new east-west Class 1 corridor that connects shippers in Mexico, Texas and U.S. southeast.

Although officially launched on Dec. 1, the companies said today the SMX is "already providing automotive, intermodal and carload customers with faster transit times, greater capacity, and environmentally sustainable rail solutions".

Monday's statement noted the Direct Class I connection brings new competition, linking the U.S Southeast to Texas and Mexico markets.

CP, which closed down $0.32 or 0.3% to $106.03 on the Toronto Stock Exchange, will release its second quarter financial and operating results after markets close on July 30.
