BNSF stock owndership

Can anyone tell me where to find a listing of the pension/mutual funds that own major blocks of BNSF stock?

Thanks.

Fidelity has a Transportation Sector Mutual Fund that invests heavily in BNSF. Its symbol is FSRFX.

Fidelity's fund invests 36% in Railroads. 5% of the fund is in BNSF, their largest investment in the plan. They also invest heavily in NS, CSX and UP (4 or 5% each).

Can anyone tell me where to find a listing of the pension/mutual funds that own major blocks of BNSF stock?
