Just received MTH 20-20745-1 Norfolk Southern SD70M-2. Inside the box they sent me a white plow instead of black. Not a big deal as I had spare parts to accommodate. A little bit funny and had to share. I'll give it a shot of flat black and see how it'll match up.
Out of all of the engines I own this one has my favorite horn, almost has a quilling effect to it. Overall probably has my most favorite soundset; startup effects, idle, shutdown effects.
