Warren Buffet's Berkshire-Hathaway Group owns 99.99% of BNSF, and has cash to be paid to those 110 or so shares of old CB&Q stock that has never been turned in(even under BN). Warren Buffet looks for good companies with management he feels comfortable with. He like the BNSF management and is usually a 'hands off' investor because of that. Seeing the massive capital imprement projects BNSF has planned for this year, there appears to be no ownership throttling the spending at this company!
I doubt if he ever owned a model train, and looks at BNSF as just another good investment.
