"With STB approval, CPKC will work with our customers and invest in new infrastructure and train services to unlock the full potential of the combined network to offer unmatched supply chain alternatives and benefits compared to other rail options through congested ports and a real alternative to highway-clogging trucks." If the STB approves the combination, CPKC would offer regular Lázaro Cárdenas to Chicago service on a single-line basis. The service provides minimal on dock dwell, a smooth and seamless border crossing and an expedited rail service, the company said. A CP-KCS combination will enable a host of new train services providing enhanced competitive alternative to existing rail service providers. The single integrated rail system would connect premier ports on the US Gulf, Atlantic and Pacific coasts with overseas markets.
