Canadian Pacific Kansas City Limited (CKPC) is a Class I railroad in North America that resulted from the merger of Canadian Pacific Railway (CP) and Kansas City Southern (KCS) on April 14, 2023. It is the first and currently the only single-line railway connecting Canada, Mexico, and the United States, operating approximately 32,000 kilometres (20,000 mi) of rail across the three countries. CPKC is headquartered in Calgary and led by Keith Creel as President and CEO.

In 2020, Canadian Pacific announced its plans to build on its sustainability initiatives and develop North America’s first hydrogen fuel cell (HFC)-powered linehaul freight locomotive.

CP’s Hydrogen Locomotive Program will retrofit an existing diesel-electric linehaul locomotive, replacing its diesel prime mover and traction alternator with HFC and battery technology to power its electric traction motors. Once operational, CP will conduct rail service trials and qualification testing to evaluate the technology’s readiness for the freight-rail sector.
