I purchased recently 2 Spectrum DCC ready Dash 8-40c diesels. A CSX and a Norfolk Southerns.They have rapido couplers.  It seams the couplers on the new engines do not line up with any of the rolling stock.They are body mounted, not truck mounted. They are too high. I thinks it is a flaw in the design. Is there a fix for this. Please HELP!
I will try to post photos later.
