I've mentioned before that I picked the corporate identity of the Inverness & Richmond Railway based on it's historic ownership by CNR, and the many subsidiaries CN owned. This choice allowed me to integrate my model into the CN family next to Central Vermont, and Grand Trunk Western.
I'm not the first one to do this however. See Marty McGuirk's awesome HO scale Southern New England Boxcars as an example.
So where does that leave me? Well, I'm currently collaborating with a gentleman on The Rail Wire who has experience with creating artwork and custom decals for model railroads. I may even have a sample JPEG by next weekend. I can only hope they look as good as Marty's.
