QUOTE: Originally posted by CSSHEGEWISCH Any breakup of Union Pacific as it is currently constituted would be difficult to impossible to process. While I agree that the UP/SP merger was handled badly by the STB, a reversal of their decision several years after the fact is not realistic. Also, the STB or the Department of Justice would need a solid legal reason to initiate a breakup or divestiture, presumably under antitrust law. UPS has a well-deserved reputation for being a demanding shipper, and with their volume, it isn't too hard for them to get their way. The real question is whether the additional expenses attached to operating a "Bullet" train for UPS are worth the additional business for the railroad in question.
