I just received my Southern Railway SD40s. Both have coupler issues. As you see in the photo the command control coupler is lying loose in the box. This is on the short high hood end. This is the second engine I opened. I did not even remove it from the foam cradle. I did not notice it right away on the first engine. On the first engine the coupler was lying loose on the long hood end. I found with the first engine four small screws that were loose and the coupler bracket lying loose in the box. I don't want to turn this into another manufacturer bashing thread but I guess from now on I am going to have to ask my hobby shop to take them out of the box and test them before they ship them to me.
