CPKC said its Mexico Midwest Express (MMX) trains offer third-day service to/from Laredo, fourth-day service to/from Monterrey, and 4.5-day service to/from San Luis Potosi. MMX provides total transit time of 98 hours from Chicago to San Luis Potosi. The railroad noted that a diverse group of shippers, moving a variety of products, will use the service.
Dedicated intermodal service between Lázaro Cardenas, Mexico and Chicago began operating as a proof of concept on an interline basis in March 2022, between then Canadian Pacific and Kansas City Southern, which merged April 14.
“The Mexico Midwest Express offers truly best-in-class service and represents the growth potential of providing truck-competitive service and reliable rail transportation options for shippers with the newly combined CPKC,” CPKC President and CEO Keith Creel said. “This is a game changer for this essential north-south trade corridor. Customers already are signing up for these new options as we compete hard to grow our business.”
The MMX announcement follows multi-year agreements with Schneider and with Knight-Swift that the Class I railroad announced last month.
