Iron Fish Plates adjoin the rails together.
Low current on standard rails supply electricity to function, switches.
Question becomes...
Could one utilize
standard rail tracks - transport electricity to mining projects,
saving considerble monies -
averting the costs to build new pole power lines ?
Low current is known to exist in standard rails.
Existing rails act the part of, electrical pole lines.
Could additional current be added / rail amplified in which to transport distant electricity
from other regions whereby ( miner ) stores in battery banks ?
