@RickM46, Sorry for the delay, had to get home from work to snap the pic. You're right, there are a lot of screws, but you only need to remove 4: two under the fire box behind the last driver and two inside the steam chests. Concerning the former, it's the two larger screws that sit on the frame, not the smaller screws that hold the smoke on/off toggle switch; about the latter, they're inside the steam chests in that square void, if you shine a light in there you'll see them. Remove those four and then the it just lifts out. There should be enough slack with the wires to clear the shell and lay it down. Attached pic with the screws indicated.
Regarding the "wobble", it is a slight up and down bobbing motion. I did try to film a video last night but it's not that obvious on camera. There doesn't seem to be much play with the wheels/frame, in either direction, so I don't think the cause is a mechanical issue. If I lay my fingers on the top as it runs I can feel the motion, but if I then take my other hand and apply some light pressure to say the smoke stack, then the wobbling virtually vanishes. I think I recall reading similar comments to the previous releases, in that this slight up/down movement isn't inherent to this release, but I haven't had a chance yet to search the forum.
