Thanks and yes, the wheels move by two gears, one on the first wheel set and the other on the third wheel set  just like the HO version.

Here's my remake of  "Toby and the Flood"  using Large Scale Toby

I talked with a guy who opened Duck up and he said,

"In the front half of Duck, the motor goes all the way up in there, sort of causing the front end to lean downward.

Bachmann needs to add some small block up in the body shell near the front. That's what I did to mine and now he's level."

I've completed two remakes with him already!
