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.
Not all, just that which was put up on the cheap.
