Blue & White BNSF??

[Cannonball]

I was going past the railyard the other day and noticed a blue loco with white trim sitting there. At first I figured it was a rental but as I went by I noticed the BNSF logo on the side in big, white letters. So are they buying the rentals now and just spraying BNSF to save painting costs or is this a new paint scheme that I haven't heard about?? Sorry I didn't get a pic. I was sans camera at the time.
