Kansas City (CPKC), the newest rail freight company in the United States, added 1,000 53-foot reefer containers for its Mexico Midwest Express (MMX) intermodal service. This means the company’s fleet is more than doubling.
CPKC was founded in March after Canadian Pacific (CP) and Kansas City Southern (KCS) merged to form one company. Both CP and KCS were Class I Railroads, the group including the largest US rail freight companies. The MMX service, the only intermodal service operating daily between Mexico and the US Midwest, was launched by CPKC in mid-May.
The MMX service connects Chicago with Kansas City, Kansas City (Missouri), Laredo (Texas), and Monterrey (Mexico), before reaching San Luis Potosi. Total transit time from Chicago to San Luis Potosi revolves around 98 hours.
The new reefer containers will move fresh and frozen produce, and food products from Mexico to the US Midwest.
