Canadian Pacific Kansas City - The 7th Class I Railroad

Here is one of the Trains forum threads, from 2021 when the CN offer looked like a ‘done deal’. This came up using the little ‘magnifying glass’ search tool (using CN KCS merger as the search terms). There were others.

Are we proposing a radical upset at the STB, and an equally radical upset in Congress to eliminate protections of the Sherman and Clayton acts on the already-overmerged North American Class Is?
