Along those lines, I recall some of the Dash 9-44CWs delivered in the late 90s faded very quickly and very badly to basically yellow. From a distance these could look like a UP engine in the consist. I recall railfan talk that GE even agreed to repaint units from one order in which the finish degraded so quickly, though I don't know if that's true. We are talking really bad fading. Even with paint jobs that hold up better, its very common to see the kinds of shading variations on the same BNSF model locomotive models. Perhaps because of that, I have yet to see a model from MTH or Lionel that didn't plausibly represent BNSF orange.
BNSF settled on orange and black as its colors in 2006 when it changed its name from "Burlington Northern & Santa Fe Railway" to just "BNSF Railway" (maybe the corporate motto is "We don't stand for anything...). As mentioned above that's the "Heritage III" scheme with the "swoosh" style logo. I think all the SD70ACes were delivered in that paint, and all ES44s were delivered that way after about 2006. I think pretty much everything on the roster now is repainted in that scheme when the time comes.
"Heritage II" is the orange and green scheme with the Santa-Fe cigar band logo across the nose and broad yellow and black stripes. That's the scheme on the SD70MACs in the original poster's pictures. That came into use about 1997 or 1998. Starting then all newly-delivered Dash 9s and SD70MACs were delivered in that scheme. A few older wide-cab models, including Dash 8s, GP60Ms, SD60Ms and SD75Ms were repainted in that scheme. I don't think any of the older standard cab locomotives were repainted in that scheme.
Heritage I is the original, Great Northern-inspired orange/green scheme with circle cross nose logos and dark green BNSF lettering. The 960 and 1000 series Dash 9s were delivered in that scheme and were the first engines to wear it. Older standard cab models also were repainted in Heritage 1, with a variation: green, rather than silver trucks. I always thought this one maybe the best of the "orange" schemes. It also seems to me at least to look the best even as the paint ages.
