Electricity is "felt" down a line more as a wave than electrons traveling the distance.
The speed of the wave is determined by the capacitance and inductance of the line (paired wires). Insulation has a different dielectric constant than air and the capacitance of the line will be different. If Wiki really had "slows the electrons down", the author does not know what he is talking about.

It sounds like this could be an issue for anyone with over 1000 meters of wire from the power station to the train. Any of you that have a half mile long layout can comment if you have seen this problem. Meanwhile, I think I'll try to finish the under-body on a Flyer gondola conversion. -Michael Eldridge -at O/S West today: got paid last night, this could be bad --- In [email protected]<mailto:S-Scale%40yahoogroups.com>, "dhultay" <HULTAY@...> wrote: > > Michael, > Not too sure if you meant to say "unshielded" wire instead of "uninsulated" > wire, > > > > BTW: according to Wiki, the signal propagates faster in uninsulated wire. > > > > -Michael > > [Non-text portions of this message have been removed] ------------------------------------ Yahoo!
