Berkshire Hathaway’s BNSF railroad is “forever better” after a capital program last year boosted capacity following complaints about congestion, BNSF chief executive told Reuters on Saturday. We think we’ve got opportunities going forward,” said Carl Ice, BNSF’s president and chief executive officer, speaking on the sidelines at Berkshire Hathaway’s annual meeting. Profits at the railroad rose 44 percent from a year earlier, when bad weather and congestion led to what Berkshire called “substandard” service that left many customers unhappy.
