We could use the railing to transmit power but nah we have to use it to house power source

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

[–] FistingEnthusiast@lemmy.world 0 points 4 months ago

Definitely not

Sometimes in the order of mere milivolts

That's already the standard in Switzerland. The overhead line is the phase and the rails are ground.
