The only ex-ATSF Dash 9 to receive BNSF lettering on the side. I only call the relettered ones Fakebonnets. Any Warbonnets with BNSF lettering that aren't ex-ATSF I just call them BNSF Warbonnets. Note that 681's BNSF lettering is bold for some reason. Only Warbonnet with bold lettering on the roster.
