Al, I'm sorry your engine arrived broken, and sorry for so many others having a similar problem. I have had the same problem trying to call Lionel. They haven't called back. I will have to call again and again. In my case it is a Western Maryland 2-6-6-2, the last one the dealer had. The rear coupler has never worked. Going to support on the Website, they tell me to go through a short reset procedure, but it didn't help. I'm going to keep calling. I can get by without the coupler working, but it should work.
