A recent thread on putting a power supply into one passenger car and tethering the power to the rest of the cars has me thinking.
It would really be neat if LIONEL would provide for a tether between a driven engine and a dummy engine. A small jack on each end of engines where the MU connector would normally go would be so neat. I was thinking about using an Electric RR Mini Commander EX in dummy engines and the lack of rollers on them is a really "expensive to solve" problem. It pretty much negates the idea of saving money buying a dummy engine.
The same connector jack on passenger cars...hey...maybe all the cars. Lets get into the 21st Century.
I don't think I would like a wire dangling from the engine or car, a jack of with some prototypical look would be best.
