Upgrading sub surface tube lines to 750V
"Mortimer" wrote
Would signalling or GSM use such high voltages? I'd expect low voltages
for anything that didn't require large amounts of power and would
therefore incur I-squared-R losses. I thought that the proposed GW
electrification would be OHLE, so why would it need 650V supplies?
What voltage do point motors run at?
