So in theory, one 25kV power station could reach out 25 miles in both directions, or a total of 50 miles of track.Excellent point. Which is why USA electric utility companies' major backbone transmission systems are at 500,000 to 765,000 Volts nominal. Also, at the retail customer level, in significant part the reason for house wiring nominal Voltages changing from years ago 220/110 Volts to present day 240/120 Volt nominal.
