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?
I can't imagine them running at 650V would be very healthy for the track
maintenance staff!
