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
