"BNSF was the major contributor adding $US 885
million to net earnings since our acquisition, including $603 million
during the second quarter," the company said in an earnings statement
this week.

Berkshire paid $26.5 billion in February for the share of BNSF it did not already own.

BNSF says second quarter revenues rose 23.5% year-on-year to $US 4.09
billion, with intermodal volumes growing 9.7% and bulk and wagonload
traffic up 11.6%.
