Hate to say it, but that's not how it works. The UP can scream all they want. The UP has the highest P/E ratio of any RR right now. In simpler terms, they can't afford a merger. Then there's the formality of the STB agreeing to it, because they have direct oversight for mergers. The government has to agree to the merger. Historically, the UP didn't do so hot on the last merger. Then there's the real time data that's shows the UP has a hard time handling the territory they already have. It would be nearly impossible for the government to agree to a UP merger with the CSX, when the current executive team is very fond of downsizing the operations. Oh yeah the government doesn't like monopolies either. The UP merging with the CSX would create a monopoly that the government would take exception to and stop the merger from ever happening. What sense does it make to downsize the company, then merge with another railroad to become bigger than before the downsizing. See the contradiction there?
