Sorry for not writing sooner, thanks for the reply. I was thinking of using the overhead wire known as a cantenary system. Distance between stops is irrelavant as evidenced by europe's use of this system all over the continent. In europe's case their intercity trains top 200mph regularly. Even Russia announced that they had just completed electrification of the trans-siberian railroad recently. That's around ten thousand miles. One writer complained about the esthetics of the overhead wire. He said it would be an eyesore. Boston, New Orleans, San Francisco, Seattle, Portland to name some have this system. I have ridden on most of them on numerous occasions & never heard or read anything from the public in the way of complaint. Again, in the beginning the capital outlay would be big but I believe the financial savings down the line would be enormous.
