Berkshire Hathaway News
Warren Buffett, the chairman of Berkshire Hathaway (BRK-A), said on Wednesday the company's BNSF railroad unit probably will not need to expand its rail car purchases as a result of delays in the Keystone pipeline construction. In addition, he said that the rail industry as a whole remains concerned about safety after a recent string of accidents. "It's true that the world is going to need an improved tank car," the iconic investor said in an interview with Reuters. Among the worries he cited was the potential for cyber attacks at Berkshire companies, particularly those with large physical facilities such as BNSF and utility operations.
