Shielding 750 volt 3rd rail ?
"Acrosticus" wrote in message ... From: Michael Bell Date: 08/08/2003 23:43 GMT Daylight Time 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. |
