Buffett's BNSF Open to Bid for Norfolk to Challenge CP's Offer

BNSF right now can interchange with NS in multiple places between Chicago, Kansas City to New Orleans.  If one key city gets blocked or snowed in, it can more the traffic.  

That said, what would happen to the KCS line NS invested in if either BNSF or CP buys NS?

Any of the mergers in this discussion will make a monopoly. Warren Buffet's BNSF already has a monopoly on the petroleum products shipping to the US from Canada. I also suspect that Buffet is a major reason the pipeline from Canada has been a no go because it will adversely affect the BNSF's monopoly. Buffet is a Democrat who pulls strings with the Obama Administration, so I am skeptical with any of his public discussions.

I could be wrong.  But I thought Sherman was, as written, is that you can have a monopoly, but could not act like one.  That is, you could be one, but not shoot prices sky high, buy out or squash competition  which may crop up.......

But to keep a monopoly from acting like one is to not have one in the first place.
