It has always seemed to me that the 750 volt 3rd rail is a bad
idea.
Too right! Massive amperages, high resistances, huge numbers of
substations in
relation to the length of a line. It's an idea that's really past its sell
by
date. If you want to electrify, do it properly with 25Kv at 50 Hertz in a
wire
up on some sticks. Tinkering about with 750v DC is about as much good as
rearranging the deckchairs on the deck of the "Titanic".
And as soon as we get some windy weather all the overhead lines come down
and the entire rail network is screwed.
