I have wanted a model of a SD70MAC since the first time I saw one in Nebraska in 1994. I even went so far as to start to build one from a SD70M. Unfortunately, I started that right before Kato announced they were making one. Then Athearn made one. My converted one is still not finished. This started off as BN 9526 but when I was comparing photos I noticed 9526 is from BN's third order of SD70MACs but came with the newer squarer fuel tank. Even though 9568 is from a later order it has the earlier, rounder fuel tank, the same as Athearn's model. So changing the number makes the details more correct. I also added some pilot detail, MU hoses and lift bars. On the front a Details West plow and on the rear spare knuckle holders. I tinted the windows with Tamiya "Smoke". The weathering is a wash of Floquil, a little airbrushing and it is all sealed with a 50/50 mix of Dullcote and Glosscote.
Here is a shot of 9568 next to a fresh out of the box sibling.
Here is a photo of it on my Freemo module.
