BigJimSo...why is the writing backwards on the video???
Hi BigJim,
I don't see any backwards writing when I view the video. Can you describe what you are seeing in more detail?

I'm just a dude with a bad back having a lot of fun with model trains, and finally building a layout!
So...why is the writing backwards on the video???

I was about to say the same thing. Great info I never knew.

Living the dream.
I watched that video a couple nights ago. Drawings, paper cups, and computer animation looks good. In real life that flange plays a huge part. I've seen wheels pass inspection with a dished running surface. Also there is hundreds of miles of track that is not round on top and lots of track with a taper to the inside negating the wheel taper. Flange squeal, and sliding wheels is just what they have to deal with. Broad curves can't be everywhere.
Feynman and Wickens both handled this better.
I can't imagine why one of the resident camera mavens hasn't rigged up an appropriate combination of optics to actually watch what the wheels and truck frames actually do as they go around layout curves.
Hint.
I did some calculations, and it appears the differential action fails at an HO radius between 165" and 330".
That means that for HO trains, the flanges are needed in curves sharper than the above.

Well, kinda OT here,
but if model railroad wheels are shaped even close to correctly, the outer edge of the wheel should not come close to touching the opposing rail in a turnout frog. Since it doesn't even touch the outer edge of the rail its riding on.
Carry on with your regulary scheduled topic....
