Thanks Pat, video was a great idea!
This first video is on straight and level track. Runs exactly how an engine with no speed regulation should.
In this video you can see the bucking I was talking about. Corners don't cause this problem by themselves, it's uneven track that causes this. But we don't have a permanent layout and we generally leave the trains set up in our basement living room. So the engines have to tolerate a little bit of track twist. All of our Legacy engines run beautifully, including a large AC-12 Cab forward. Track is freshly cleaned, the layout is powered multiple places. I'm at a loss!
