The latest news in the world of finance is the acquisition of Burlington Northern Santa Fe, the nation's second-largest railroad by none other than investment guru Warren Buffet. This has turned many heads because of the mammoth scale of the deal which is $34 billion and is the largest ever investment made by Warren Buffett's Berkshire Hathaway investment company. Berkshire Hathaway Inc. already owns a 22 percent stake in Burlington Northern and would buy up the rest under the deal, for a total value of $34 billion. It still needs approval from Burlington shareholders and antitrust regulators, both are expected early next year. Buffet feels that investment in railroad is wise one because of the escalating diesel prices that would make transport through trucks a costly one. Building a new railroad isn’t that easy as well. One has to wait and see if Buffet’s bet pays off or not.
