Trying my hand at Weathering

Tried my hand at weathering tonight and dirtied up the BNSF ES44DC a little bit. So many different textures to repaint, in total I think I had to do 12 separate textures to get it this far. It's not a super heavy weathering but I think gets rid of that 'clean' look that all the engines come with.
