INFORMATION TO BE INCLUDED IN THE REPORT

Item 7.01 Regulation FD Disclosure

The operations of BNSF Railway Company, the principal operating subsidiary of Burlington Northern Santa Fe Corporation (“BNSF” or “Company”), have been adversely impacted by recent severe weather in the Midwest.  The flooding that has occurred in this region continues to cause network outages and disruptions to BNSF’s operations. BNSF will also need to conduct repairs to its infrastructure once the flooding recedes.

In addition to weather issues, fuel prices have continued to rise and are now significantly above the level assumed when BNSF provided second quarter earnings guidance. Therefore, while the final impact of the flooding is not currently known, BNSF currently estimates its second quarter earnings per share to approximate $1.30, excluding the effect of a recent jury verdict in Minnesota arising from a 2003 quadruple fatality grade crossing accident which BNSF anticipates will reduce earnings by $0.03 per share and the environmental costs discussed in a May 6, 2008 Form 8-K filed with the SEC relating to costs of environmental matters in Montana.
