We could use the railing to transmit power but nah we have to use it to house power source
That's already the standard in Switzerland. The overhead line is the phase and the rails are ground.
In what world is it reasonable to put a several kilovolt line on the ground? Even subways have safety problems with the third rail.
Damn you want kilovolt? I was thinking few hundred at most. Over a few miles it would be fine to power like lights and low powered devices
There is usually a current present in the rails already
Either traction current, signalling current for track circuits, or both
Depending on the way the signalling system has been engineered
Hmmm neat. I guess those are high voltage signals
Definitely not
Sometimes in the order of mere milivolts
