Ok im noob at this hobby here and i need help. In my layout i want to run a SD40 or a SD40-2 by athearn or bachmann. My question is what is the min radius i can run with these loco's. All my layouts ive done using RTS 7.0 have 18" ers. Do i need to do another one that has a 22" radius? If it helps the layout size it goin to be 4x10. If by some god alfull reason i cant do 22" ill stick to my orginal plan and get a few GP35's.

18" would be ok, but it would not look realistic. 22" is the best choice. If you are going to be running long cars (73",86",89",65" possibly) you would want 24".

The bachmann might handle the 18" but all my Athearn's skip a wheel off the track in 18" radius turns, they're more suited to the 22".

ok change of plans. Im going with some GP35's. I like the look plus they seem to fit the "power" need for my layout. If your wondering about the layout its a made up oil company. Ill have more for you later in the year about it.
