With my SD40-2 (Rio Grande) I kind of took the middle road and put 6 wheels
in the back and used the 4 wheel train motor in the front. I know it's not
exact, but we do have to work with in the limits of LEGO parts. I did try
match the fans and side vents the best I could. Orginally they were going to
be SD40Ts but a T unit (tunnel) has the side vents down low and the Rio
Grande decal wouldn't work if I did that....so I just made them into SD40s
