www.trainiax.net/ I found a site other that paintshop.railfan.net for railroad drawing the other night. It has more that P.R.N as well. Here are some drawings i did. 
What do you think? Colin
Did you do the actual diesel drawings, or just the color schemes on them? There is a difference.
I’d check those again if I werer you, I think that’s the same designer as the RR Paintshop. No harm done in a mistake, it;s not like your selling them.
The paint sceme is all i did. Im not sure if its the same guy, i just saw the website name. Colin
