Are there any dummy / non-powered Emd SD40 available anywhere? there seems to be several F4 type.
Yeah, look for the old Athearn Blue-Box Kits, they made tons of them. I'm just confused as to what you mean by F4 type, do you mean F3s??? They had 4 non-powered SD-40s at one of my Local Hobby shops. They had 2 Southern Pacific, 1 Conrail, and 1 B&O.
Ive seen a few on eBay and 1 at a train show but thats about it. So their might be some left. Do a little looking around.
