well, it couldn't pull ALL the cars I have
I need to figure out the traction issues on the other F9 so I can doublehead
I also have 2 ten wheelers (plus one awaiting delivery) that I am guessing I need to do some analysis on, as they alway derail, at the exact same spot within the inch after they go thru 2 turnouts without issue(thanks scsshaggy for the tips, they helped) and I do not see anything obvious not caused by swollen traction tires, I removed one and tested, still failed if the third engine does it too, (but neither F9 or chuggy boi does), then I am assuming a design flaw that I might need to fix
burned out a powerpack by using an atlas twin switch wrong. the nice one that didn't have a reversing switch

more detail
exact same spot, the last inch of a 18r curve before the 6 wheel set hits the end of track rails are flat and smooth no bumps or obstructions under the section train acts like it pops the wheels off, almost as under force. like the flanged wheels arecockeyed or the rails are not the right width(they are)
like I said, needs more testing, the track was full of rolling stock so I couldnt putz easily enough and only two blocks wired so far

I can think of a couple of things to check on the 10 wheelers.
One would be if the blind drivers are on the rails. I once had an engine on which the blind drivers did not always reach the outside rail of a curve, and they could drop down and catch an edge on the inside edge of the rail. I ended up fixing that by shimming up some slack between the axles and the frame cover plate.
The other would be whether the pilot truck is running smoothly through the curve. There can be cases when the wheel is hitting against a cylinder or when it can't swing far enough to the side and starts lifting up the wheels on the inside of the curve. That could cause some sideways pressure like you describe.
Carpe Manana!

Nice video!
As far as your other Tyco F9 that has traction issues, that is probably due to the fact that the traction tires need to be replaced/are dry-rotted, or there are no tires left at all.

I did replace the tire
yeah, tire, one of the driven wheels does NOT have a tire groove
3 pole motor, the good working one is 5 pole :)
now that I have replaced the axle(thanks chops), I might do some measurements on it and try to build a gear for the stripped one, and then use that to replace the tireless driver wheel
which means designing/building a wheel gear puller, turning down a bolt to appropriate axle size, and all sorts of other fun stuff to do

GUess what I learned today
the pilot trucks have a front and a back. the front is 2mm longer than the back. putting them on backwards after cleaning causes them to do as I described
so tonight is time to finish stage one and two wiring of turnouts, then running of a number of engines to get them better assessed at to repairs needed, or just run in.
I know one of the ten wheelers has a badly connected wire (just twisted) and I have another ten wheeler on it's way. I only wanted one but I expected more issues so I bought the others for parts
