Canadian National Railway (CN) reaches an agreement with Union Pacific that would end CN’s opposition to Union Pacific’s proposed U.S. merger involving Norfolk Southern, according to multiple reports. The arrangement is described as a trade-off: CN stops opposing the deal and, in return, receives additional network access in parts of the U.S. Midwest. One report characterizes the expected merger value as about US$85 billion. The details of the added access were not fully specified in the excerpts provided. The agreement is presented as a coordinated change in CN’s stance on the proposed transaction rather than as a separate corporate combination. Overall, the coverage aligns on the central points that CN and Union Pacific are negotiating terms linked to the U.S. mega-merger, CN’s previous opposition would be withdrawn, and CN would gain expanded operating or connectivity opportunities through the deal’s structure. The reports do not describe timing, regulatory outcomes, or specific operational terms in the provided text.
