Roger,
They did and I had one. The flywheel was powered by a rubberband to a plastic drum pulley mounted on one of the axles. It performed much like a rubberband. Most of my cars have Interrmountain standard or semi fine scale wheelsets and they mimic the momentum better than the flywheel gimic. If you pre-pposition your Kadees so that they will not couple, you can with practice, switch on the fly.
Real brakemen don't use uncoupling magnets,

Did not NWSL offer a flywheel chassis that could be used with an Athern
box car to simulate train momentum?

about cheaper. It would provide a sort of brake when stopped, but it
certainly would push the train along when moving!

Re: Scale Weights - Doubt It

(snip)

Then after accomplishing this you run into the problem of how our
layouts

aren't actual scale

models, in fact most don't even approach being scale. Most are so

drastically foreshortened that a

1:1 freight car's dynamics when scaled down acting under the forces of

momentum would roll much

farther than most of our sidings and yards are long. A freight taking
a

mile to stop would take how

many dozen laps of most of our layouts to achieve that? That's if you

don't have a point to point,

in that case it just goes over the edge because the world is flat.
Here

there be dragons and they

find model railroad equipment to be tasty. That's why it keeps

disappearing off the edge of the

layout, never to be seen again. :-)

The more you try to mimic the prototype the more you end up
demonstrating

the reality that our

models are basically toys, well, expensive toys.
