Why Bill Gates And Warren Buffett Are Railroad Rivals

But as Bloomberg's Frederic Tomesco and Thomas Black report, even though both billionaires are philanthropically entwined, when it comes to the old-school realm of investing in North America's railroads, Gates and Buffett part ways.

Tomesco and Black write:

It seems perfectly logical for Buffett to own a railroad company. His much-lauded investment philosophy hinges on putting money only into businesses he can understand - in terms of operations, products, and, crucially, opportunites.

For Gates, on the other hand, being a latter-day railway tycoon seems far less in-character. A tech titan owning a big chunk of a business that runs on mid-20th century technology? Well, maybe Gates and his advisors just asked themselves "What Would Warren Do?"

But Buffett, because Berkshire Hathaway owns BNSF, is effectively running the railroad. He's also responsible for promoting its story, which since he took over the company, has been an uplifting and compelling one - a tale of American comeback, cast in terms that excite the little kid in everyone.

Trains! Who doesn't get a thrill witnessing a long freight train, loaded with America goods bound for American markets and ultimately American customers, rolling through the America landscape?
