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, Rob Manley
