RAILROADS (U.S. STB RATE REGULATION & “CAPTIVE SHIPPERS”) / U.S. Surface Transportation Board orders BNSF Railway Co. to delay revaluation in its assets “to transition the revaluation over seven years to reduce the possible impact on captive shippers”. U.S. STB notes that Berkshire Hathaway, Inc. in its 2010 purchase of the railroad company had “failed to obtain agency authorization for its purchase of BNSF, as required under federal law.”
