Clinchfield Alt Liveries
Clinchfield's F7A and SD40 in black and gray, respectively: the liveries DTG didn't include. Suitably grimy, for a railroad that famously never washed its locomotives.

Where is the F7B? Well, only one of those was ever painted black, and the game AI would spawn it over and over, so I thought it best to leave it out.
