In the NYC subway system electricity is delivered through three-conductor cables to transformers and converters in sub-stations suitably located along their track system (Broadway, 7th Ave, 6th Ave, Lexington. Ave etc.) I'm sure each station at least has a on/off switch that allows electricity to be supplies to the rails of that specific station.
