OMAHA — Legendary investor Warren Buffett said he will offer $34 billion to buy Burlington Northern Santa Fe Railroad. BNSF, which runs through Ottawa, is the nation’s second-largest railroad. It would be the biggest acquisition ever for Buffett’s holding company Berkshire Hathaway. Berkshire Hathaway already owns about one-fifth of the railroad’s shares and will pay $100 a share in cash and stock for the rest. In a press release, Buffett said the offer represents a huge bet on the company and the economic future of the United States – the kind of bets he likes.
