[UK-CONTEST] OT- Railway electrification

[Clive Whelan]

Please forgive the OT subject, but I know what a wide expertise resides 
here. Off-list replies would be indicated.

You may have heard about the electrification of the Paddington/Swansea 
line in the recent news. Well I live within yards of that line in the 
old station master's house in the local village ( pre-Beeching!), so I 
will almost certainly have to move. I did consider this possibility when 
moving here about 9 years ago, but though it would never happen on 
economic grounds if no other- how wrong I was? Of course nobody chooses 
to live alongside a railway line , but being an impecuniously challenged 
person, I would not otherwise been able to afford the property! In 
reality the environment has not proved any problem at all.

Even though a move of QTH will almost certainly prove imperative, I 
don't have any direct personal experience of such things, and wonder if 
anyone here does? I don't even know what the voltage used is, but 
imagine it must be several kV to minimise I- squared-R losses? Is the 
QRM transient ( like the audio) or is it propagated along the cables. My 
best guess is that it must be?

Any info appreciated.
