Good News. I figure out why the train is sagging. it has to do with the battery terminal design on Peter Sam. The wheel well for Peter is way deeper than the Plarail Nagasaki 2x series 3000. It forced one set of wheels in the middle carriage to sink in. Unfortunately i forgot to take a photo before replacing the motor. See photo below.

I tried to harvest a motor off several spare Spencer sadly none of them work
. So I harvested the motor off Neville. Voila it works perfectly. I believe Donald, Douglas, Bill and Ben uses the same battery terminal design.

While I dig for my spare Spencer, I found the other Plarail Nagasaki 2x series 3000 I had, they have the same coupling system.
