The Surface Transportation Board's announcement refers to the new railroad as follows:
Competition – The combination of the two railroads,
to be known as Canadian Pacific Kansas City (CPKC), will create the first railroad providing single-line service spanning Canada, the United States, and Mexico. Yet, CPKC will continue to be the smallest Class I railroad, with a network that is a few thousand route miles shorter than the next smallest Class I and half the size of the Western railroads.
